Outdoor top column circuit breaker rod type high voltage circuit breaker
Porduct Description
Outdoor post circuit breaker
Used for transmission projects with long power supply radius, large voltage drop and low voltage The phase switch can not only be used as the section switch on the 12kV distribution trunk line, branch line and ring line of urban network, but also be used as the input line switch in rural network, industrial and mining enterprises, living quarters and construction sites.
Product Application
Product Advantages
1. The circuit breaker adopts three-phase pillar structure, vacuum arc extinguishing technology, and has the characteristics of stable and reliable closing and breaking performance, no risk of combustion and explosion, maintenance free, small size, light weight and long life, etc.
2, the circuit breaker adopts fully enclosed structure, the vacuum arcing chamber in the conductive circuit and the inner wall of the outer insulation sleeve adopts the silicone rubber sealing casting method, the sealing performance is good, improve the moisture-proof, anti-condensation performance, especially suitable for cold or wet areas.
3. The three-phase pillar and current transformer adopt imported outdoor epoxy resin solid insulation, or indoor epoxy resin solid silicone rubber insulation;With high and low temperature resistance, UV resistance, aging resistance and other characteristics.
