The outlet voltage of wind/photovoltaic power generation units commonly used in China is 690V, which must be boosted to achieve the purpose of long-distance power transmission.In the wind/photovoltaic field general cable to connect the generator to use special box step-up voltage rises to 40.5 or 12 kv to wind/photovoltaic field center substation, and then by the center to the power grid, after further step-up substation photovoltaic wind motor/generator with the box-type pressure change the combination of using just one unit connection.The 40.5 and 12kv wind power booster and photovoltaic booster designed and developed by our company are designed and developed in order to meet this demand.
1.35KV wind power generation combined type transformer substation (high voltage oil immersed type switch)
2.Dodge gate applies the technology of cold-rolled sheet and aluminum zinc coated steel plate, stainless steel metal double sandwiches.
3.Roof is blown, and cabinet color is grey
