XGTD7-(12/24)40.5 Indoor Gas Insulation Mental-clad Switchgear

General introduction

XGN (XGTD7)-(12/24) 40.5 series indoor gas-insulated metal-clad switchgear (hereinafter called "C-GIS cabinet") is a switchgear which uses a spring-operated vacuum circuit breaker, electrically operated three station isolation / earthing switch,CT/PT lightning arrester as the main components, and completely seals all HV conductors in the metal-clad enclosure with gas as the insulating medium.

The product has features of flexible combinations, great safety, complete interlocking logic as well as extensibility, miniaturization and free for maintenance. So that it was commonly used in infrastructure construction for power station, power substation, movable transformer pack, 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.GB3906 3.6 ~ 40.5 kVAC metal-enclosed switchgear and control equipment
