35KV High Voltage Circuit Breaker

Chengdu 35KV High Voltage Switchgear Factory Chengdu 35KV outdoor vacuum circuit breaker is an outdoor high-voltage switchgear equipment with a rated voltage of 40.5kv and three-phase AC 50 (60) Hz. It can be used for breaking and closing load current, overload current, and short-circuit current, and is widely used in rural power grid power systems. The product complies with the GB1984-2003 standard. The overall structure of this product is a porcelain bottle pillar type, with a vacuum arc extinguishing chamber inside the upper porcelain bottle and a pillar porcelain bottle as the lower porcelain bottle. The three phases are installed together in one mechanism box, and the arc extinguishing chamber moving end is connected to the operating mechanism through a crank arm and an insulating rod. Easy to operate and convenient. In order to ensure electrical safety, the circuit breaker can be supported by a bracket with a height that meets the distance between the charged body and the ground. Users can also choose a concrete bracket instead of a metal bracket.

35KV High Voltage Circuit Breaker

The standard bracket height for circuit breakers is 1300mm for mid mounted and 1200mm for high-altitude mid mounted. Instructions for use: Altitude: not higher than 2000m, plateau type not higher than 4000m. Environmental altitude: -30 ℃~40 ℃, lower limit of low-temperature circuit breaker -50 ℃. Relative temperature: The daily average is not greater than 2.2 kPa, and the monthly average is not greater than 1.8 kPa. Seismic intensity: below level 8. Electrical anti bounce can be added according to user requirements. Wind pressure: ≤ 700Pa (equivalent to a wind speed of 34m/s) Air pollution level: ordinary level III, special level IV. When used under normal environmental conditions beyond those specified in GB/T11022-1999, users can negotiate with the manufacturer to resolve the issue.
