Product Description
LW36-72.5 self-contained power HV AC sf6 circuit breaker
Description:
LW36-72.5 self-energy outdoor HV AC sulfur hexafluoride circuit breaker is an outdoor three-phase porcelain column
electrical equipment mainly used in AC 50Hz, 72.5kV electricity systems in extremely cold regions (for electric stations in
general regions and -40ºC extremely cold regions). This product can be operated frequently and used as a connection circuit breaker.
Structural features
1.High performance -strong rated circulating ability: strong short circuit breaking ability at 3150A, -40ºC: 40kA.
2.Long service life -electrical endurance: 31.5kA×21times (25kA×31times); mechanical life: 6000 times without maintenance and up to 10000 after simple adjustment.
3. High reliability -sharing the arc extinguishing compartment structure with LW36-126; great product internal insulation
redundancy; over all cast aluminum alloy frame adopted for the spring structure; simple structure and high reliability; suitable for frequent operations.
4. Reliable breaking performance.
5. Reliable sealing performance; Annual leakage of SF6 gas ≤0.5%
6. Meeting the requirements of hard running environments -suitable for Class IV polluted places and -40ºC~+40ºC environments.
7. Multi-structure forms-usually porcelain column type and handcart type.
