YBP(M)□-12 prefabricated substation is a complete intelligent power supply and distribution device optimized with new environmentally friendly materials, new technology, advanced high and low voltage technology, it has multi-function and wild usage with reliable operation and good appearance. It can combine with the surrounding environment to design a variety of different styles and shapes. It has features of easy installation, less land requirement, less maintenance, less investment and long life. It can be used as power distribution equipment for urban buildings, residential areas, municipal facilities, factories, mines, roads, gardens, piers, oil fields and temporary power supply and other departments.
● Altitude: not exceed 1000m;
● Ambient temperature: -25℃~+40℃; average temperature within 24h should not exceed +30℃.
● Quakeproof level: horizontal acceleration not exceed 0.4m/s2, vertical acceleration not exceed 0.2m/s2; No severe vibration, shock or explosive danger in the installation site.
● According to whether it can be equipped with intelligent system, it can be divided into: Intelligent type; compact type.
● The cabinet body (shell) materials: metal shell; non-metallic shell.
● Non-metallic shell is precast synthesized by non-metallic fiberglass and special reinforced concrete, it has high mechanical strength and good impact resistance, it has low thermal conductivity, and it has fireproof and smoldering features, compared with metal shell, it has better corrosion resistance and extremely long life and other characteristics.
