The product uses the latest intenational design concept and epoxy resin encapsulated silione rubber APG insuation technology as welll as precision processing technology. The technology is in the domestic
leading level.
The features are as follows:
1.The product adopts three phase pillar structure, compact design,
stable and reliable breaking performance, no fire and explosion
hazards, maintenance-free, small size, light weight and long
service life.
2. The circuit breaker can be equipped with integrated
disconnector, and has reliable mechanical interlock between
disconnector and circuit breakers, to prevent misoperation.
3. The circuit breaker is fuily enclosed structure with good
sealing performance, high anti-moisture, anti-condensation
propertes specially suitable for cold or wet areas.
4. Three- phase column and CT are adopted imported outdoor epoxy
resin solid insulation material casting. It has the features of
high temperature resistance, UV resistance, anti-aging
characteristics, and it can ensure long-term outdoor safety.
5 The circuit breaker uses the small size spring operation
mechanism, low enery consumption during open-close. lts
transmission adopts direct drive method, and less open-close
parts,high relability. lts operation mechanism is sealed in the
mechanical box ,which solves corrsion problem of switch parts so as
to improve the reliability of circuit breaker.
6. The open-close operation of the circuit breaker can use manual
operation, and motor operation.It can be equipped with controller
to realize distribution automazation as well as combined with
recloser controller as automatic recloser.
7. The circuit breaker can be equipped with two-phase, three- phase
and zero-sequence CT to provide data analysis for overcurrent
automatic release protection and smart controller.
