No fire, explosion,serious filthy,chemical corrosion and violent vibration of places.
If the customers have other special requirements, can be in order to put forward, our company can offer most satisfied.
Operating mechanism is sealed in the switch box body, which can effectively avoid the switch for long-term outdoor environment mechanism caused by the corrosion. Operating mechanism of novel,simple,reliable operationsmall size, mechanical life of up to 10000 times. Can be arranged outdoor isolating switch and circuit breaker to form integrationcircuit breaker and isolating switch has reliable mechanical interlocking device. |
The circuit breaker by three-phase support, body box, simple structure,threephase support and current transformer using outdoor epoxy resin solid or silicone rubber insulated, having high and low temperature,rsistance to ultraviolet light and aging resistance,etc.; the small spring operating mechanism, on-off brake low energy consumption,transmission output spindle sliding mode, no torque loss and drivingless, high reliability; current transformer is installed on the movable end outlet, a two time using inserting-dialing structure, convenient maintenance and replacement.
The interrupting performance is stable and reliable, has no combustion and explosion isksafe operation, maintenance free, small size, light weight (<100kg)and long service life etc..
The circuit breaker adopts a totally enclosed structure, good sealing performance, moisture-proof,anti condensation performance,suitable for hot and humid area.
Breaker, switching can be manual or electric operation and remote operation. With the controller supporting implementation of distribution automation and can also be composed with recloser recloser controller.
