Product Description
VIB-24
Series of Indoor High Voltage Vacuum Circuit Breaker With Embedded Poles


General Description
VIB-24 series of Indoor High Voltage Vacuum Circuit Breaker with embedded poles is three phase A.C.50Hz indoor power distribution equipment with the rated voltage of 24kV.It's used for protecting and controlling the electrical equipment in the fileds of industry&mining enterprise,power plants and substation.
The main conductive circuit of this type vacuum circuit breaker with spring mechanism is embedded pole,that can greatly improve the reliability of insulation,mechanical and breaking performance,and really realize the free-maintance and longer mechanical&electrical life.
This type Vacuum Circuit Breaker conforms to national standards and the stipulation of IEC standard.The capability reaches grade of M2-E2-C2.
The products is used for many kinds of switchgear like KYN28-24(GZS1)and can be fixed installation.

Applying ambient conditions
1.Ambient temperature:-10ºC~+40ºC.
2.Ambient humidity:the average value of a day should be no more than 95%;the average value of a month should be no more than 90%.
3.Earthquake intensity:not exceed 8 degrees.
4.Water vapour pressure:the average value of a day should be no more than 2.2kPa;the average value of a month should be no more than 1.8kPa.
5.The height above sea level:≤1000m(besides the special requirements).
6.It should be installed in the place without fire,explosion,serious filth,chemical erosion and vibration.
