4. Recloser feature
4.1 Outline of recloser:
The RCW series vacuum recloser is mainly combined
with integration terminal, current transformer, permanent
magnetic actuator and its recloser controller.
4.2 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 M length(8M for special). .
Its can performance serve more than 20 years long term under heavy duty circumstance.
4.3 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 ~ +200 ℃.

5. Main new advantages of RCW
High reliable manual opening device
Visible ON/OFF indicator
High reliable manual closing device
IP64 class waterproof plug connector
Note:
ROCKWIILL Supply special design manual closing device technology with own patent,It applied for
nomal and abnormal situation closing. Its closing speed(time) comply with IEC62271-100.
This function can offset from magnetic actuator fault which when ctuator can’t work will cause the
major accident..
