Introduction:
Our VS1 indoor vacuum circuit breaker (VCB) is the latest domestic achievement. It is available in many varieties, excellent in performance, and widely applicable to:
a. energy and infrastructure: power plants, 220KV/110KV substations, primary and secondary distribution systems.
b. industrial production: power supply systems for pulp and paper, construction materials (glass, cement,ceramics), steel and metal products, aluminum, petrochemical and other industrial productions.
c. building:power supply system of large-, medium-sized buildings and residential areas.
d. other: petrochemical, transportation, and mining areas
Complete Series
Rated voltage: 10kV (12kV), 20kV (24kV), 36kV (40.5kV)
Rated current: 630A, 1250A,1600A, 2000A, 2500A, 3150A,4000A,
Rated short circuit breaking current: 20kA, 25kA, 31.5kA, 40kA
Technology Leader
The use of the world latest embedded pole distinguishes the VS1 indoor high voltage circuit breaker from others. The embedded pole is based on epoxy resin and cast by the most advanced technology. Vacuum interrupter, primary conductive circuit parts and isolated rod are enclosed together in the embedded pole to achieve a complete separation between the conductive circuit and the exterior. The structure is miniaturized and maintenance free, while having high dielectric strength, so as to allow the vacuum circuit breaker to run normally in harsh environment.
Flexible Configuration
The operating mechanism of the VS1 vacuum circuit breaker is of positive arrangement, allowing fixed and withdrawable mounting methods as well as manual and electric drive methods. The mechanism is suitable for ABB-UniGear, SIEMENS-NXAIR, SCHNEIDER-NVNEX and TELLHOW-KYN28A series medium voltage switchgears.
