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:
