Overview
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, mines, roads, gardens, piers, oil fields and trmproaty power supply and other departments.
Structure
● 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 shll,it has better corrosion resistance and extremely long life and other characteristics.
Service Condition
● 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.
Matters Need Attention For Hoisting Transportation, Operation And Installation Of Cubicle Substation:
● Surrounding of the foundation of cubicle substation shall be embedded with grounding electrodse,transformer and lightning protector can share the grounding system, grounding resistance shall be ≤4 Ω
● Use special hoisting tool for lifting the cubicle substation,must use the marked parts on substation for hoisting
● Junction part of the substation bottom and foundation should be sealed with cement to prevent sater from entering into the cable chamber
● After the cable is set in the cuale sleeve,its gap must be sealed to prevent from pests or water.
