GIS Gas Insulation Metal Clad Switchgear Indoor Type XGTD8-12

1. General introduction

XGTD8-12 indoor environmental gas insulated metal-clad switchgear (hereinafter called "the panel") is a switchgear that filled with environmental gas with features of green and environmental friendly, reliable operation, reasonable design, small volume, free maintenance, long life and strong adaptability to environment.

The panel and its primary live parts are enclosed in stainless steel shell which free from the influence of outside. It adopts modular design to achieve the combination of same panel type and extended unit according to different schemes and arrangements. It can meet the demand of compact switchgear for secondary transmission and distribution substation. Also, I can be widely applied in secondary small distribution substation, industrial and mining enterprises, airport, railway, commercial district, high-rise building, expressway, subway, tunnel and other places with sever condition.

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.
