Product Description

What is the standard of Rockwill Auto Recloser？

Rockwill Auto Recloser is a flexible pole mounted outdoor vacuum switching device that can trip and reclose up for a temporary distribution line fault. It reduces the blackout time greatly and improves the stability of power grid operation. The operation status also can be controlled and monitored by mobile phone and SCADA system.

Rockwill standard auto recloser is fully meet the Standard IEC62271-111 & ANSI/IEEE C37.60. Fully follow the above standard for type test and routine test. Additional functions reuirement is offered, like: ESKOM standard, TANESCO standard, BPC standard, SEC standard, DEC, Meralco, KPLC, BREB, etc. Besides, Rockwill even provide with patent design for new recloser.

RCW+ Auto Recloser

RCW+ type auto recloser is ANSI/IEC standardized plus design products which is equipped with one magnetic actuator mechanism, one manual closing/opening/Locking device, 3 current sensors, max 6 voltage sensors, with more functional like protection curves + curves programble, coodination logics + logics programble, programble communication protocols(Modbus, DNP3.0, IEC 60870-5-101/104), PC software, APP control tool, etc.

RCW+ type auto circuit recloser is a solid insulation reclosure with zero pressure Sf6 GAS sealed. with high creepage design, higher insulation level, suit using for Maximum 42kV level sytem.

It's vacuum interrupting technology, and IP67 IP protection class, It avoid any bad influence high polution enviroment of humidity, salt or alkali incursion or small animal,etc...
