4 Introduction Veneta Isolatori is a leader company specialised in the production of MV epoxy resin insulators for electrical and electromechanical industry. The company was established in 1974, in 1990 it became a subsidiary of COMEM S.p.A, leader in oil transformer component and solution. In 2009 all the activities were moved to a new factory located in Ceggia close to Venice. The long experience achieved by Veneta Isolatori gave the possibility to develop a wide range of products, having suitable and tested electrical and mechanical technical characteristics. Recently the company has also developed insulators in silicon rubber for outdoor installation. Nowadays Veneta Isolatori represents a reference point for many of electrical companies, that use Veneta Isolatori partnership for the development and realisation of insulators according to their own basic design. The export, almost 50% of the total production, cover a winde range of countries and MV application. 2

5 Certification The Quality System conforms to the ISO 9001 Standards, the Environmental Management System conforms to the ISO Standards and the Health and Safety Management System conforms to the OHSAS Standards, also regarding application in building site activities. All the systems are certified by an external independent organisation. Laboratories The Unit has internal laboratories equipped with state-of-theart apparatus for carrying out tests on materials, experimental, climatic, mechanical life, dielectric and partial discharge. Operation Each design parameter is known, measured and recorded for each piece of insulator produced, so that their functional suitability can be declared in accordance with what is prescribed in the Standards. Production is also supported by lines which operate using the fabrication system with functional blocks. Thanks to this innovative system, the production lines can outfit each typical unit with maximum efficiency and speed. 3

36 Type PGS kv SF6 - Air silicon rubber bushing General characteristics A The PGS bushings can be used as a fixed part for medium input on SF6 gas or oil insulated machines. It is provided with a coupling interface according to DIN standard that allows a connection with the relevant movable connectors. It is forbidden to use the bushing in outdoor applications without the relevant movable connectors or without the silicon rubber protection (B). A+B The PGS bushing with the silicon rubber protection can be utilized outdoor for connections with bare electrical wire. The PGS can be assembled in any position except for the situation where the sheds of silicon rubber protection are turned upside down, even if slightly.

37 Assembling instruction PGS bushing (Fig. 1 and 2): Drill the holes on the body of the tank as indicated (9). Remove the paint, or insulating coat, in the area of the fixing fastener holes in order to guarantee a correct earth connection of the bushing. Moreover make sure that the surface where the bushing holds is without any type of roughness, or unevenness and it must be perfectly clean in order to guarantee a perfect tightness of the flat gaskets. Place the bushing (7) on the metal structure after having positioned the gasket (8). Place the aluminium flange (10) inside the tank and tighten the six fixing screws (11) together with the relevant washers with a tightening force value of 9 11 Nm. The tighting of the screws must be done crosswise. The lower connection to the M10 threaded hole must be fixed with a tightening force value of Nm. Fig. 1 Fig. 2 H mm - Mod kv H mm - Mod kv Silicon rubber protection (Fig. 3 and 4): Remove the plastic protective cover (4) from the bushing. The plastic protective cover must be fitted and pressed right down on the bushing always when: the bushing is not connected to the movable connector; the bushing does not have silicon rubber protection. This prevents faults caused by dirty or incidental scratching of the interface (6). Clean with alcohol the interface (6) and the area of contact with the silicon rubber protection (3). After the complete evaporation of the solvent, spread evenly over the connection interface (6) the grease contained in the enclosed pocket (5). Pull the silicon rubber protection (3) on the bushing (7) and screw down tightly until maximum torque is obtained ( Nm). This can be done with the aid of a 20 mm spanner used on the top cap (2). The silicon rubber protection is correctly clamped if the bushing is totally covered with it. Turn the silicon rubber protection slightly to the left and to the right to distribuite grease evenly over the connection interface (6). Fig. 3 Fig. 4 L - 68,5 mm - Mod kv L - 108,5 mm - Mod kv 35

38 Type BSL Composite insulators for line switches General characteristics The composite insulators type BSL are suitable to be used in MV line switches. These insulators are realized with a fiberglass and epoxy resin core and aluminium end fittings and covered by silicon rubber. This material gives best performances for an outdoor use: abrasion resistance against UV rays, in environements with very high pollution level and with high salinity concentration. Silicon is unbreakable and hidrophobic. It is not necessary to plan any maintenance operation, even in particularly difficult environement conditions. Application Outdoor line switches.
