Product Description

40.5KV Fixed Type Vacuum Circuit Breaker VCB with Emebedded Poles(VIB-40.5)


General Description
VIB-40.5/T type indoor high voltage indoor vacuum circuit-breaker is used for switchgear KYN61-40.5(Z).
It's the most new type of power supply and distribution equipment.
This product is in accordance with GB1984-2003 standard. 


Structural characteristics
This kind of VCB with adopt integrated design, It's different from open-type and insulsted cylinder type vacuum circuit breaker:
The vacuum interrupter and conductive circuit connectors is encapsulated in the embedded pole through a special process with epoxy resin.
Assembled the circuit breaker with modularized mechanism.

This kind of VCB with excellent electrical & mechanical properties, it represents the advanced level of the vacuum circuit breaker  in the modern world.


Technical Characteristics 
The design of this kind of VCB take into account the Chinese market and special areas requirements, it makes the vacuum interrupter and  conductive circuits into a pole by the advantage of the solid insulation and advanced technology of APG. This is not only simplifies the pole
assembly process to prevent the connecting bolt loosening during operation, but also improve reliability and  reduce the effect of external  mechanical force and environment(such as:dust,humidity,nasty,high sea level,animal), and avoid that VI's operation lower caused by  vacuum interrupter operating in adverse environment, which can lead potentional accident of VI's surface flashover as VCB opening, So the pole is free maintenance within the service life of the extrnal insulation. It's more environment. 
 

Applying ambient conditions
Ambient temperature:-15~+40ºC,the average temperature is not more than 35ºC in 24 hours.
The height above sea level:≤1000m
Relative humidity:the average humidity of a day should be no more than 95%; the average humidity of a month should be no more than 90%.
Saturated vapor pressure:the average pressure of a day should be no more than 2.2kPa; the average pressure of a month should be no more than 1.8kPa.
It should be installed in the places without dust, smoke, chemical erosion, combustible gas and saline fume pollution.
