SF6 insulated load switch underground substation Reclaim factory-sell-directly

Program for Tuesday, May 24th· ABSTRACT. 1. INTORODUCTION Recently, room load is on the decline caused by reduction of internal heat gain and improvements of thermal performance of building fabric. At the same time, it could be expected that outdoor air load become invariable. As a result, the proportion of outdoor air load for air conditioning would be greater.

SF6 (GIS) gas insulated substation Manufacturer in China ... SF6 gas insulated substation (GIS) is assembled by several SF6 gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of SF6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could operate in stable condition for more than 30 years.
