Product Detail
Transportation:by sea;PaymentType:FOB Ningbo;Trademark:Tianan;
DXG-40.5(z) Indoor Gas Insulation Metal-clad Switchgear ( hereafter referred to as "GIS") is high tech products, which are researched, developed and manufactured by introduction of technology from Long Yuan Electric Power Research Institute, affiliated with China Electric power Federation. Besides it is up to GB/T11022and GB3906 [3-35KV AC Metal-clad Switchgear] standard. It is featured by high reliability, free of maintenance, less occupied area; The main technical parameter has reached an international advanced level.
Product feature :
The DXG-40.5(Z) GIS is suitable for power plant, substation, combined substation and electric power system, which is three phase indoor AC single busbar and sectioning single busbar with 50HZ, 35kV rated voltage, used to control, accept and distribute electric power.
