Product Highlights

Integrated Functionality & Comprehensive Protection

The SR-JXB series integrates disconnector, zinc oxide arrester, discharge gap, and current transformer into a single assembly. Features full functionality, compact size, easy installation/commissioning, and high reliability.

Precise and Reliable Protection

Overvoltage protection employs corrosion-resistant stainless steel hemispherical rod-shaped gaps. Ensures stable characteristics with precise coordination to arresters and transformer bushings. High thermal capacity prevents burnout, enhancing protection security and reliability.

Superior Corrosion Resistance

Electrodes manufactured from stainless steel. Equipment base hot-dip galvanized. Disconnector operating mechanism housing and instrument transformer enclosures constructed of stainless steel plate.
