Overview
DRM6 series gas insulated compact type metal enclosed switchgear (hereinafter GIS ), its cabinet with armored structure, between the bus room and switch room, switch room and cable compartment has metal clapboard, primary protection grade of full insulation structure can reach IP67.
Load break switch with three position welding in sealed stainless steel tank filled with SF6 gas , gas tightness is very good, with less gas, which can guarantee 30 years without leakage, and meet the requirements of environmental protection, It is suitable for indoor and outdoor configuration equipped with metal or non metal shell, or put the underground, semi-underground substation using.
The operating mechanism adopts corrosion resistant metal, rotating part of the bearing for lubrication design , the products is not affected by the environment from regular maintenance, and convenient connection with the outside world, so that the operation power small, high reliability and long service life.
The extended bus is made of a plug — in silicone rubber connector, which is fully insulated and shielded to ensure the reliability of the transmission and is not affected by the surrounding environment.
The combined connection and expansion is convenient, which is convenient for the capacity expansion of the user or the substation in the future.
