GW-12 Series 1250A Outdoor Rated Voltage 6--12kV High Voltage Disconnector Switch
The GW-12 series isolation switch, locking and operating principle are the same. The double-column structure, simple, strong, double-silver-plated copper bar, forging terminal board, base and trip and other spare parts are manufactured with precision grinding tool, and the matching is accurate and reliable. As a product specially used for outdoor use, the design and materials take fully into account the special requirements of operating environment, acid and alkali resistance and aging resistance. The post insulator may be of a ceramic type, a silicone rubber or a resin type.
