Photovoltaic power generation has pure green, no pollution, and can be seamlessly connected with existing power transmission and transformation grids. Therefore, Balic Electric has given sufficient attention to the grounding network of emerging energy photovoltaic power plants. Photovoltaic power generation is mostly in the remote suburbs of the wilderness. It covers a huge area and is extremely vulnerable to lightning hazards. The grounding network maintenance work of the supporting booster substation is huge.

The grounding grid made of traditional hot-dip galvanized steel is difficult to guarantee the service life of more than 10 years. The copper and copper-clad steel grounding material can make the grounding net life reach 30 to 50 years. The price of pure copper material is high and the strength is less than that of copper-clad steel. From the comprehensive comparison of performance and price, the copper-clad steel material produced by the Balic is the best material choice for the photovoltaic field grounding system.

The photovoltaic power grid grounding network is mainly composed of the photovoltaic power generation area grounding, the inverter room grounding and the lightning protection belt, the boosting station grounding, etc., and is connected to each other. Generally, a centralized grounding device is arranged at the grounding down conductor line of the inverter room for discharging. Thunder current. The grounding arrangement is buried depth of 0.6-0.8m and below the permanent frozen soil layer. They are all composed of horizontal grounding wire + vertical grounding pole + grounding lead wire, etc. The materials are made of copper-clad steel grounding material, and the welding method is Balic heat-dissipating welding.
