Fixed Contact Jaw Assembly

Fixed contact jaw assembly for double rotating turn twist type isolator. Current rating range from 400 A to 3000Amps. The contacts have provision to align easily at site. Application:- The Rotating Isolator is a triple pole double break /Single break isolator, which is mechanically or electrically gang operated and designed for any kind of demanding outdoor application. It is ideal to suit overhead systems, used in high density urban situations or high load centers, where the load is much higher and the situation calls for enhanced and stable quality supply. The key function of the isolator is to segregate the Transformer, Overhead lines, System or Cables from distribution network. Construction:- The rotating isolators have a triple pole construction, makes it perfect to be used in horizontal upright mounting. Each pole consist of galvanized steel base, solid core or post type insulators of premium quality, EC grade copper fixed and moving contacts. G.I. coupling pipe of sufficient length for rotating operation, required length
