2 B8/8 Introduction Metalfree (ADSS cables) and metal-armored (OPGW, OPPW) aerial cables with integrated optical fibres (called optical fibre aerial cables) are used to transmit information. The information is transmitted by means of modulated light pulses in the interior of the thin optical fibres. These fibres have a total diameter of approx. 300 µm. The optical fibre aerial cables can be stressed upto <!--[if!supportemptyparas]-->a limited tensile force without any increase of the optical signal damping in the fibres. However, in the case of a radial force, the optical damping will increase by bounds. This increase can lead to a reduction of the information flow through the fibres. The fibres with an additional length are beded in one or several relatively rigid coaxial tubes to avoid inadmissible stress. In the case of metalfree optical cables the tubes are beded in a supporting structure of aramid fibres. The optical fibre cable is finally covered with an extruded PE-mantle. The core of the metall-armored aerial cable is covered with one or more layers of Aluminium wires, Aluminium alloy wires or Aluminium-clad steel wires. As the optical fibres have to be protected against inadmissible radial forces during and after the installation of optical fibre aerial cables the fittings at the tension-, suspension- and fixing points have to meet special requirements. For common conductors and ground wire we use fittings for tension and suspension points which provoke the necessary grippage force by effecting of a high radial force (for example wedge type tension clamp, suspension clamp). Due to the high pressure sensitivity of optical fibres beded in the aerial cable these types of fittings are not suitable for optical fibre aerial cables. The fittings of the RIBE-Optofit-program are designed regarding this high pressure sensitivity. The fittings are especially adapted to this purpose. The induced radial forces are spread over a larger contact surface (for example dead end) in such a way that the fibres are not inadmissibly stressed and the necessary grippage forces are achieved. It is impossible to determine standardized accessories for optical fibre aerial cables as the structure of the different cables is very manifold. Fittings for optical fibre aerial cables mainly consist of the following group of fittings: - Helically formed fittings for tension and suspension points - Earth connections - Tower down-lead accessories - Vibration dampers Helically formed fittings form the major part of accessories for optical fibre aerial cables. They are composed of helically formed rods which - according to the respective application - are separate or preassembled, straight or bended on delivery. Helically formed accessories can be used to tension, to suspend or to connect conductors, optical fibre aerial cables, glass fibre rods and solid rods such as guys. In addition, helically formed accessories are used for protection or repair of conductors or optical fibre aerial cables, for attachment to post insulators and for tensioning of street lighting. Helically formed accessories have been used very succesfully since The application of helically formed accessories is not at all limited to overhead lines. Helically formed accessories are also used to a large extent for the construction of antennae, radar stations etc. The principle of operation of helically formed accessories is based on the principle of the development of a low pressure over a large area. The inside diameter of the unloaded helical rods is slightly smaller than the outside diameter of the conductor, optical fibre aerial cable or solid rod. By wrapping the helical rods on a conductor or optical fibre aerial cable, a spring tension is created, producing the necessary frictional contact. This spring tension is elastic and ensures a constant grip. To ensure the full performance, helically formed accessories must exactly be adapted to the outside diameter of conductor, optical fibre aerial cable or solid rod. In general, helically formed accessories are made of a material similar to that of conductor, optical fibre aerial cable or solid rod. Usually this garanties a similar corrosion resitivity. Installation of helically formed accessories can be done without any tools. Installation faults are nearly impossible. Mounting instructions are available on demand. Helically formed accessories are largely protected by patents or registration of designs. If helically formed accessories are required for applications other than those included in this catalogue, a specific inquiry is requested. The RIBE numbers of helically formed accessories start with a combination of letters that is followed by six figures and possibly letters added at the end. for example: AG The respective letters or figures have the following meaning: 1) Starting letters The first capital letter and in some cases the first and the second letter designate the respective type.

10 B800/0 Introduction to armour grip suspensions Design and performance: The armour grip suspension is used for the movable suspension of conductors and optical fibre aerial cables on suspension towers. The armour grip suspension is composed of a certain number of helically formed rods, a concave Neoprene insert consisting of two halfs and a clamp body. The helical rods are placed on the Neoprene insert at the suspension point. This centre assembly is fixed by the clamp body which due to positive locking prevents axial displacement of the conductor. The armour grip suspension - like the application of suspension clamps along with armour rods - does not impede asymmetric vibration and thus avoids local alternating bending stress. This is no static compression force existing in standard suspension clamps with and without armour rods due to the keeper with bolts. This is the principle difference of the armour grip suspension compared to suspension equipments commonly used up to now. The reinforcement of the cross-section by armor rods improves the lifetime of the vibrating conductor/ optical fibre aerial cable. However, it is no damping device to cope with conductor vibrations. The electrical connection of the helical rods and the suspension equipment is resistant to short-circuit current, i.e. it is capable to conduct the short circuit current of a conductor/ optical fibre aerial cable without damage. Helical rods and clamp bodies are made of high-tensile, corrosion-resistant aluminium alloy, inserts of Neoprene, straps and threaded bolts of hot-dip galvanized steel. Installation: The Neoprene composed of two concave halves is placed on the conductor/ optical fibre aerial cable at the suspension point and attached by the helical rods which are wrapped on the conductor/ optical fibre aerial cable with insert. The clamp body of the suspension equipment is placed on either side of the centre assembly thus that is embraced by the clamp body. The clamp body is attached by application of a bolt. Apart from a tubular hexagon box spanner, no special tooling is required for assembly. The assembly has to be performed in accordance with RIBE-Mounting Instruction No. 10. Stand: 10.

28 B810/0 Introduction to helical dead ends 1... Helical dead end 2... Thimble 3... Black crossing mark Design and performance: Helical dead ends are ideally suited for the full tensioning of self supporting optical fibre aerial cables. Dead ends are composed of five or more preassembled helical rods which are covered with a small-grained sand on the inside to improve the frictional contact. The loop of the dead end is protected from abrasion by means of a thimble. The deformation of the cable is omitted as the radial compression is distributed over a large contact area. The helical rods are made of a high-tensile, corrosion-resistant aluminium alloy, of high-tensile hot-dip galvanized steel, or Aluminium-clad steel; thimbles of hot-dip galvanized malleable cast iron and cotter pins or threaded bolts of hot-dip galvanized steel with tensile strength class 8.8. Installation: The legs of the dead end are wrapped on the cable starting at the marked crossing point. Special tooling is not required. For installation follow RIBE-Mounting Instruction No. 9.

They are mounted beneath the helical dead end and spread the radial forces on the cable uniformly along the zone of contact. Especially on the cable at the loop-side of the helical dead end radial forces (depending on the tension force) can stress the optical part of the cable inadmissibly. This will cause high damping which results in a reduced data transmission or in the worst case an interruption. The length of the cable guard is determined in such a way that two vibration dampers can be mounted on the rods at the span-side avoiding that the damper clamp is stressing the optical part of the cable. For optical fibre aerial cables with right-hand outer layer, cableguards with left-hand layer are always used in order to avoid a torsion of the cable by the helical dead end with right-hand layer. A torsion of the aerial cable is causing an enlenghtening leading to a destruction of the optical part of the cable. Installation: The helical rods can be wrapped on by hand in bundles. Tools are not required for the assembly. Prior to installation the cable must be cleaned along the overall lenght of Stand: 12.

Thimble: Steel, h.d.g.; malleable cast iron, h.d.g. These dead ends are particulary designed for the full tensioning of ADSS cable in short, medium and long spans. Three ways of application are possible: for short spans (up to approx. 70m) and small forces: : The dead end is mounted on the cable starting at the black crossing mark. This leads to a long cable loop and a large bending radius of the cable. A thimble can be used in the loop of the dead end. for medium spans (approx m) and high forces: Stand: 10.

37 The dead end is mounted on the cable starting at the red crossing mark. This leads to a short cable loop. Additional intermediate fittings for installation at the tower and a thimble are necessary. for long spans and high forces: The use of protection rods (URA: see data-sheet B814/1) is recommended. When selecting the helical dead ends the total diameter resulting out of the cable diameter plus two times the rod diameter of protection rods has to be taken into account. Remarks: For installation follow RIBE-Mounting Instruction No. 9. Furthermore the rated forces of thimbles are observed (see data-sheet B821).

These dead ends are designed for the full tensioning of the separate support cable (left-hand outer layer). The advantage of dead ends compared with tensioning devices commonly used is that there is no bending of the relatively stiff supporting cable. It is recommended to protect the dead end loop from abrasion by means of a thimble. These dead ends can be used to suspend self supporting figure-8-cables too. Two dead ends per suspension point are required for any such application (see figure below). Fig.: Mounting example for suspending self supporting cables Installation: Dead ends can be installed and removed quickly and without application of any tools. Wrapping of dead ends starts at the crossing mark. For installation follow RIBE-Mounting Instruction No. 9. Remarks: These dead end designs are only suitable for left-hand layer steel support cables. When placing an order please state if dead ends for righthand layer support cables are required. Thimbles: see data-sheet B822 Stand: 10.

They are mounted under the helical dead end and reduce the radial forces in the cable - especially at the loopside of the dead end. Radial forces (depending on the tension force) can stress the optical part of the cable inadmissibly. This can cause high damping in the optical fibre. This results in a high signal damping in the optical fibre up to an interruption of the optical transmission. Installation: The helical rods can be wrapped on by hand in bundles.

Protection rods are preferably made of steel, h.d.g. and shall protect the self supporting fibre optical aerial cables at tension sets. They are mounted beneath the helical dead end and spread the radial forces on the cable uniformly along the zone of contact. Especially on the cable at the loop-side of the helical dead end radial forces (depending on the tension force) can stress the optical part of the cable inadmissibly. This will cause high damping which results in a reduced data transmission or in the worst case an interruption. The length of the cable guard is determined in such a way that two vibration dampers can be mounted on the rods at the span-side avoiding that the damper clamp is stressing the optical part of the cable. For optical fibre aerial cables with right-hand outer layer, cableguards with left-hand layer are always used in order to avoid a torsion of the cable by the helical dead end with right-hand layer. A torsion of the aerial cable is causing an enlenghtening leading to a destruction of the optical part of the cable. Installation: The helical rods can be wrapped on by hand in bundles. Tools are not required for the assembly. Prior to installation the cable must be cleaned along the overall lenght of protection rods. Fig.: Mounting example Stand: 10.

88 B850/0 Introducing to vibration dampers Aeolian vibrations: Under certain conditions phase conductors, ground wires and optical fibre aerial cables in transmission lines are excited to mechanical vibrations by wind. These are causing alternating bending stresses which superpose to the static tensile bending stress. Suspension- and tension points are especially endangered. As shown in practice for an undamped aerial cable these stresses cause fatigue breakages of single strands with the possible result of a complete breakage of the optical fibre aerial cable and subsequent breakdown. Efficient protection against aeolian vibration is given by the installation of suitable vibrations dampers. Purpose of vibration damper: Vibration dampers are combined frictional resonance dampers. Purpose of vibration dampers is to dissipate partly the wind power input on the conductor or optical fibre aerial cable to prevent critical cable stresses. Function of vibration damper: The vibration damper consists of a messenger wire with specially formed weights fixed on both ends. The clamp, to mount the damper on the conductor is fixed between the weights on the messenger wire and transfers the vibrations from the conductor or aerial cable to the messenger wire. The mechanical vibration energy is transformed within the messenger wire to heat caused by friction. High power dissipation within the small range of natural frequencies is a characteristic feature of most vibration dampers. Under field conditions, however, a wide band of natural conductor frequencies has to be expected. Therefore, the dampers must be effective within a wide frequency band and allow only small residual conductor/ aerial cable amplitudes. Selection of vibration damper: The vibration damper, i.e. it s mechanical properties (impedance), must fit for the conductor or optical fibre aerial cable. If not, either the damper can cause damages at its clamp on the conductor or aerial cable, or the damper itself can be destroyed. Location of vibration damper: To ensure the optimum efficiency of the vibration dampers, it is necessary to adapt the optimum damper design to the given conditions. This adaptation requires the determination of the exact damper placement and the number of dampers required. The most suitable vibration damper is ineffective if it is located in the vibration node, because the conductor or aerial cable is nearly not moving at this point and thus no vibration energy is transformed into heat. This case must be avoided by determination of a suitable location. If tension points are concernd this is often only possible with big efforts. In this case two dampers must be located on the conductor or optical fibre aerial cable nearby the tension point. Thus, it is for sure, that at least on damper is working. Damping concept: Every damper is capable to transform a certain amount of vibration energy into heat, without being overloaded. As the vibration energy is increasing with the length of the span, for longer spans several vibration dampers have to be installed. In special cases, as for example river crossings, additional damping has to be provided inside the span. The damping concept gives information about the damper location, the necessary quantity of dampers considering the length of the span and the type of damper (for example messenger wire made of stainless steel, clamping range etc.) The damping concept is developed with a computer vibration study. Given the conductor and damper properties, for every installationarrangement and span-length it is proven that the strain of conductors or optical fibre aerial cable (admissible bending strain = 150 µm/m) and vibration dampers remains uncritical and will not cause fatique breakages. Selection of vibration damper clamp: The selection of a suitable vibration damper clamp occurs after selection of the vibration damper type. The suitable clamp prevents excessive strain of optical fibres in a cable. For aerial cables additional protection rods are necessary. When determining the vibration damper clamp the total diameter resulting out of the aerial cable diameter plus two times the rod diameter of the protection rods has to be considered. By means of clamping tests the optimal clamp size and recommended tightening torque of the bolt are determined.

The Avibra vibration damper is composed of a helically formed plastic rod. About one fifth of the overall length of the helix is of smaller diameter. This section is used to attach the damper and provides a completely reliable grip on the ADSS cable so that the damper will not slip even on slopes. The remaining length of the helix has no close contact to the cable. Due to differential motions between ADSS cable and Avibra damper, the ADSS cable vibrations are eliminated. Installation: Avibra vibration dampers are installed by first wrapping the gripping section (smaller helix) and afterwards the damping section on the optical fibre aerial cable. The damper must be installed in such a way that the gripping section is placed towards the tower and the damping section towards the free span. No special tools are required for installation. Avibra vibration dampers can be installed without problems on any existing cable - even subsequently. For installtion follow RIBE-Mounting Instruction No. 17. Stand: 25.
