15kv auto circuit recloser insulated electrical equipment used for
automatic circuit breaker 3 phase type outdoor embedded poles
Features
- It adopts pole embedding technology, uses a potted vacuum bottle
for fault interruption, and is insulated by epoxy resin and
silicone rubber.
- A magnetic drive mechanism combined with an optional spring
mechanism enables shutdown and trip operation when the battery is
exhausted within the expiration date. Three-phase systems are rated
for voltages up to 27kV, continuous currents up to 800A and
breaking currents up to 20kA.
Application
Used for automatic circuit breaker.
