General Description:
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.
Technical 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 an 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 ratio 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 the 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 replaces 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.
