Recloser feature:
1.Outline of recloser:
The Recloser series vacuum recloser is mainly combined with integration terminal, current transformer, permanent magnetic actuator and its recloser controller.
2. The recloser tank feature:
The Vacuum recloser tanks are manufactured from 304 grade stainless steel and are powder coated
a light grey colour.
Whole recloser IP65 protection class, equipped with a auxiliary plug to connect with recloser controller by control cable, Diameter Max22mm,6 Mlength(8Mfor special). .
Its can performance serve more than 20 years long term under heavy duty circumstance.
3 The recloser vacuum embedded pole feature:
The recloser's vacuum interrupter insert in an epoxy resin solid pole, and external coated with a high reliable, stable material:Fluorocarbon silicone rubber (γ-trifluoro propyl methyl polysiloxane)
With excellent electric insulation, weather resistance, ozone, biological inertia, can be stand under the long-term use in -55 ~ +200ºC.
