Prefabricated substation (European type)
- The box color can be selected so as to match with the surrounding environment. The case is made of SMC, stainless steel sheet and composite board to meet different customization requirements.
- The substation base is made of galvanized box iron or cement, so it is strong in corrosion resistance.
- The top cover of the cabinet has a double-layer structure and has good heat insulation, radiation protection and ventilation effects.
- There is an automatic exhaust device on the top of transformer room to regulate the indoor temperature.
- Be applicable to the places without severe factors such as fire hazard, explosion risks, serious dirt, chemical corrosion and violent vibration, widely applied to outdoor power supply places such as cities, residential communities, hotels, hospitals, plants and mines, airports, railways and wharfs currently.
