Disconnecting Switches

Technologie Ruscan Inc. supplies electrical contacts and contact subassemblies for most of the types of disconnecting switches for power production and power transmission; among others are vertical break, telescopic, central break, side break, pantograph and semi-pantograph disconnecting switches. The voltages vary between 14 kV for production equipment up to 735 kV in the field of transmission. The electrical contacts must be able to conduct currents as high as 18,000 A in production and 4,000 A in transport. Depending on the application and specifications, we supply solid silver electrical contacts with copper or aluminum base materials, as well as electroplated electrical contacts. Reverse engineering is used for the electrical components whenever production drawings are no longer available.
