Components of a box-type substation

1. Box Structure: The box of the European-style substation consists of three parts: the base, the shell, and the top cover. The base is generally made of channel steel, angle steel, flat steel, steel plates, etc., which are welded or bolted together to form a structure. To meet the needs of ventilation, heat dissipation, and cable entry and exit, strip holes and appropriately sized round holes should be opened in the corresponding positions. The box shell and top cover are formed by bending, welding, or connecting with screws, hinges, or related special accessories using channel steel, angle steel, steel plates, aluminum alloy plates, color-coated steel plates, cement boards, etc.
