FZW32-405 series high voltage AC Vacuum load switch is applied in the three-phase, AC50Hz, rated voltage up to 40.5KV, rated current 1250A electric-supplying network. Mainly applied in three-phase RMU net pr ending electric-supply city distribution station and industrial electrical equipments, with load-control and short-circuit protection.
The load switch can match relative manual operation mechanism or electrica motor operation mechanism.
Altitude: below 3000m
Air temperature maximum is +40ºC, minimum is -30ºC.
Relative temperature: diary average ≤95%, monthly average ≤90%
No frequent shrink shock.
1. Vacuum arc blow out, no explosive danger, no need to inspect
2. Isolation knife switch are interactive to three-phase vacuum arc extinguish chamber, obvious fracture exists when breaking.
3. Component parts all adopt stainless steel material, bottom bracket adopts stainless steel material or carbon steel material of hot-galvanized with UV protection coating To ensure device normally run in outdoor environment.
4. Strong breaking capacity, safety, reliable, long electrical life, frequent operation.
5. Widely used in rural network, city network, reconstruction of rail distribution wires
