Description

Indoor H.V. VCB VS1-40.512-40.5KV,three-phase 50HZ 400/630A, AC/DC 110/220V CCC,ISO9001,CE, CB,IEC60898

Product Introduction

VS1-40.5/T type indoor high voltage vacuum circuit breaker is used for switchgear KYN61-40.5(Z). It's the newest type of power supply and distribution equipment. This product is in accordance with GB1984-2003 standard.

Structure Features

This kind of VCB adopts an integrated design and is different from open-type vacuum circuit breaker and insulation vacuum circuit breaker.
1. The vacuum interrupter and conductive circuit fitting with ring raise resin through the special craft are sealed into a pole.
2. Then with the modularized circuit assembled in a modular circuit breaker.
3. This kind of VCB with excellent electrical&mechanical properties the advanced level of the vacuum circuit breaker in the modern world.

Normal service condition

1. Ambient temperature: -15℃ +40℃, the average temperature is not more than 35℃ in 24 hours
2. Height above sea level:≤1000m;
3. 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%;
4. Saturated vapor pressure: the average pressure of a day should be no more than 2. 2kPa, the average humidity of a month should be no more than l.8kPa;
5. Environmental conditions: It should be installed in places without dust, smoke, chemical erosion, combustible gas, and saline fume pollution.
