GW4-126KV / GW4-40.5 Outdoor Medium Voltage Disconnector

GW4-126(D)(W) disconnector is a kind of HV outdoor electric equipments used in three-phase AC 50Hz electrical system. It is used for switching -on/off the HV circuit when there is no load in the circuit in order to change or transfer the circuit and also disconnect the current with the bus bar, breaker or any other HV electrical equipments when overhauling the circuitry.

Meaning of Type

Introduction

The GW4-126(D)(W) disconnector is a kind of HV outdoor electric equipments used in three-phase AC 50Hz electrical system. It is used for switching -on/off the HV circuit when there is no load in the circuit in order to change or transfer the circuit and also disconnect the current with the bus bar, breaker or any other HV electrical equipments when overhauling the circuitry.

Thedisconnector is a double-post plane interrupter mid-opened type. It can match ground switch on 1 or 2 sides. It uses CS14G、CS17G or CS11 manual operating mechanism or CJ series electromotor operating mechanism to realize three-phase linking operation. The ground switch uses CS14G、 CS17G manual operating mechanism to realize three-phase linking operation.

Thedisconnector conforms to the standards of GB 1985-2004, DL/T486-200Xdisconnector=””ground=””switch=””>,GB/T 11022-1999, DL/T395 -2006which is constituted for the State Grid Corporation of China.
