Product Description

RCW-27~38kV Series Reclosers is a new generation of multi-function. This product employs advanced technology throughout the whole design. It integrates the functions of control, protection, measurements, communication, fault detection, on-line monitoring of closing or opening. It can carry out Substation Automation and distribution automation. This product can be used as the switches in 20kV up to 35kV line and 20kV up to 35kV outline of distribution. It can be also used as the switches in poll, It is suitable choice to realize distribution automation and miniaturization Substation.

Technical Features:

Uses imported outdoor Compound silicon rubber for insulated material. The device has light weight, long life and is able to endure hash outdoor climate. It has no oil or gas, environmentally friendly.

Advanced DSP is used in this system. The device integrates the functions of control, protection, measurement and communication.

The device uses the integrated sensor technology and can be monitored and measured on-line.

The circuit-breakers can be closed or open in-phase. This can restrain over -voltage and surge current in operation effectively. This feature has special advantages with capacitors.

Rich Communication methods. The recloser can communicate through GPRS modem and support English or Chinese short messages.
