ZGS20-G.F-40.5/0.8-3150
Hua-style box-type substation
The ZGS20-G.F-40.5/0.8-3150 series Hua-style compact substation (hereinafter referred to as compact substation) is a special device that increases the voltage of wind turbines from 0.6~0.8kV to 35kV before grid connection. The compact substation is a new product developed by our company based on user needs and combining the advantages of European and American-style substations. This product reduces the cost of European-style substations and solves the problems of insufficient protection in American-style substations and poor ventilation and heat dissipation of the main transformer in European-style substations. This product is applied to various wind power generation sites and is the best supporting product for wind power generation systems.
