Product Description

High Voltage Dry Type Plug-in SF6 Horizontal T Joint
 

Overview

•The FZX type XLPE Dry Type Plug-in SF6 Horizontal T Joint applied for cable branching, which simplifies the power net structure. 2500A current is allowed for the FZX110 type branch box, the inner case is filled with SF6 compressed gas. •The box is equipped with explosion-proof jacket, pressure meter, annunciator and valve for gas charge/deflate, etc. Box and bushing are assembled in the factory,
while GIS termination is installed locally after being tested.
