XGTD5-(12,24)40.5 Indoor Gas Insulation Metal-Clad High Voltage Switchgear
General introduction
(XGTD5)-(12/24)40.5 series indoor gas-insulated metal-clad switchgear (hereinafter called "C-GIS panel") is a switchgear which uses a spring-operated vacuum circuit breaker, electrically operated three station isolation / grounding switch, transformer, lightning arrester as the main components, and completely seals all HV conductors in the metal-clad enclosure with SF6 gas as the insulating medium.
The product has features of flexible combinations, great safety, complete interlocking logic as well as extendibility, miniaturization and free for maintenance. So that it was commonly used in infrastructure construction for power station, power substation, movable transformer pack, rail traffic, buildings that have the 35kV or below nominal voltage. Especially for some sever environment like high altitude, heavy pollution and high humidity.
The product quality assurance is based on researching, developing designing and producing required by quality system and continues to improve. So it is completely complying with the newest version or revised version of following standard, but not limited to them.
