Product Description

Liugao boldly stands as the premierHigh-Voltage 40KV Indoor Vacuum Circuit Breaker supplier. ThisHigh-Voltage 40KV Indoor Vacuum Circuit Breaker is meticulously crafted for applications demanding frequent operations at the rated operating current or locations prone to multiple short-circuit breaking currents. Setting itself apart, this VCB adopts an integrated design, distinguishing itself from open-type vacuum circuit breakers and insulation vacuum circuit breakers.

The process involves sealing the vacuum interrupter and conductive circuit fitting with a ring, raising resin through a special craft, and integrating them into a pole. Subsequently, the modularized circuit is assembled into the modular circuit breaker. This type of VCB boasts excellent electrical and mechanical properties, placing it at the advanced level of vacuum circuit breakers in the modern world. Trust Liugao for cutting-edge solutions in High-Voltage Indoor Vacuum Circuit Breakers.

High-Voltage 40KV Indoor Vacuum Circuit Breaker Operating Environment

1. Ambient temperature: -15℃一+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 the places without dust, smoke, chemical erosion, combustible gas and saline fume pollution.

High-Voltage 40KV Indoor Vacuum Circuit Breaker Breaker Characteristics

The design of this kind of VS1-40.5/T takes into account the Chinese market and special areas requirements, making the vacuum interrupter and conductive circuits into a embedded pole by the advantage of the solid insulation and advanced technology of APG.

This not only simplifies the pole assembly process and prevent the vacuum interrupter circuit conductive connecting bolt to run the VS1 ration as a result of loose, but also improve reliability and avoid the effect of external mechanical force and ambient conditions (such as dust, humidity, nasty, high sea level, animal), and avoid the potential risk of vacuum interrupter operating in adverse environments caused by insulation and then lead to a lower level of vacuum circuit breaker in the sub-gate under vacuum interrupter surface elastomer. Therefore, within the service life of the circuit breaker, the pole is completely maintenance-free. The circuit breaker’s solid insulation replace SF6 to meet the need for external insulation. It’ s more environmental protection and represents the advanced level of the vacuum circuit breaker in the modern world.
