4 Complete coverage of the market worldwide in all standards Local market leader with global competence Eaton s product series are distinguished by their strong presence in all regions of the world. In markets that adhere to IEC standards, Eaton s Moeller line is very well established, and in the world of UL/CSA, Eaton is a key player, for example with its Cutler-Hammer line. Now all customers are benefiting from first-rate engineering and the combined know-how in research and development no matter which standards they use. South Africa Eaton acquired the CHI Control business through the acquisition of Actom Low Voltage, South Africa in July In terms of organisation, product and production techniques, CHI Control is being fully integrated into Eaton, adopting the Eaton Business System, a single system covering work processes, tools and tooling. The CHI Control logo is now being replaced by the Eaton logo on product rating and carton labels and associated marketing materials with a phased completion date of 1 July The CHI Control name and logo remain registered trademarks of Eaton Corporation.

6 1.1 Standard millbank resistors 1 Features Standard NEMA dimensions Standard NEMA end-plates Taps on every second grid Stainless steel grids Double insulation Argon gas welded seams Eaton s Type MG double insulated standard resistor millbanks are employed in every conceivable type of resistor application. A standard millbank is one in which each grid in the bank is identical with a continuous current path throughout the unit. In addition, a standard millbank is equipped with a tapping point on every alternate grid. There is a maximum of 21 standard banks only. With this quantity in stock as spare units, any breakdown can be corrected immediately by simply removing the defective bank, replacing it with a similar unit from stock, and reconnecting on the same tapping points. The illustration on the right shows that the standard MG range of millbanks is fully double insulated from grid to tie rod and then from tie rod to mounting end-plate. The substantial insulators have a 100% South African design and manufacturing content. They are manufactured from highly resilient glass polyester. Similar insulators separate the grid stack from the resistor tie rods. The complete range of MG millbanks are made from quality Carpenter chrome steel, which defies rust and corrosion. They are preferred units to every large crane user, as well as to the mining industry for rotor circuit control and, as listed on page 10, for neutral earthing duties.

They differ only in that they contain three electrically separate sections. Typical applications will be 3 phase rotor resistors; 3 phase primary resistor for squirrel cage motors; 3 phase resistor starting of a closed transition Star-delta starter. 3 PG banks are also double insulated to withstand the severest of crane and industrial motor control requirements.

9 Type WL custom built resistor banks 1.3 Type WL Custom Built Resistor Bank 1 Features and Construction Standard NEMA dimensions Standard NEMA end-plates Stainless steel grids Double insulation Argon gas welded seams The type WL resistor banks are assembled on a grid to suit basis, ie. different sizes to suit ohmic and current values per section of starting resistance. Separate phases in a single bank are insulated from each other by means of glass polyester insulators. The type WL banks are physically identical to the MG bank dimension wise and use the same grids but in different configuration. They can be less costly than millbanks but as they are purpose-built it is not feasible to carry spare units.

10 1.4 Neutral earthing resistors 1 Typical Neutral Earthing Resistor Unit Covers Removed Features Eaton manufactures a large range of neutral earthing resistors for the South African market. The units are free standing, natural air cooled and enclosed in heavy duty sheet steel enclosures. They can be insulated for voltages up to 11kV as standard and have short time ratings of 10, 20, 30 and 60 seconds. The resistor is made up of standard millbank units. External connections Two connection points are provided on the enclosure. One is ceramic 3,3kV/11kV insulated through-bushing, for external connection to the transformer star point. The earth connection will be to a heavy brass stud mounted on the side of the enclosure 300mm from the base. Enclosure This is fabricated from 1,6mm sheet steel, suitably braced and welded to form a rugged free-standing unit. Its design is such that it affords complete electrical clearance and mechanical protection for the internal units, plus full protection from the environment. It is designed for outdoor use. The four side covers around the enclosure are held in position with Hex-head bolts. The front and rear covers are fitted with handles to facilitate removal and handling. All metalwork is pickled and epoxied to a high grade finish. Colour - Cutler-Hammer grey. Short time ratings Ampere rating at 500ºC temperature rise Bank Ohms 10 sec. 20 sec. 30 sec. 60 sec.

13 Spool resistor units Type L 1.5 Features Continuous element Robust construction Uniform size Light in weight and compact Wide range of capacity and resistance values Spool resistor units are made of spiral grooved porcelain bases wound with advance or nichrome wire; the wire is wound on a mandrel and then wound on the spiral base which results in well ventilated and high wattage capacity units. The ratings specified are maximum for units mounted in free air. If units are mounted where ventilation is restricted or mounted close together the maximum wattage rating is reduced. For such conditions, resistors in well ventilated enclosures can be rated at 80% and in unventilated enclosures at 65% of maximum wattage. 1 Type L - Spool Resistor Unit Ordering information Ampere ratings per NEMA class numbers Ohms Cont Cat.
