● Recloser feature a)Outline of recloser:
The RCW series vacuum recloser is mainly combined with integration terminal, current transformer, permanent magnetic actuator and it’s recloser controller.
b)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 IP67 protection class, equipped with a auxiliary plug to connect with recloser controller by control cable, Diameter Max22mm, 6 M length (8M for special).
It’s can performance serve more than 20 years long term under heavy duty circumstance.
● Main new advantages of RCW High reliable manual opening device High reliable manual closing device

Visible ON/OFF indicator                               IP67 class waterproof plug connector
ROCKWILL ® Supply special design manual closing device technology with own patent, It applied for normal and abnormal situation closing. It’s closing speed(time) comply with IEC62271-100. This function can offset from magnetic actuator fault which when actuator can’t work will cause the major accident.


Primacy incomer terminal (directly connect to interrupter reduce power lost) Current sensor (external modular design easy for quality control and maintenance) Accuracy: ±0.5% Ratio:800/1

Internal Voltage sensors incorporated within the vacuum interrupter module. Accuracy: ±0.2 % Voltage Sensor, Ratio:500/1 or 1000/1.

It’s equipped with two voltage sensors, one for measuring the voltage of incoming side, and another one for measuring the voltage of outgoing side.
