Overview
Low Partial Discharge: Under 80% power frequency withstand voltage, the insulation is less than 2pc, and the partial discharge value of the whole bay is less than 5pc;
Low Leakage Rate: The butt flange surface is specially designed for double sealing structure, and its annual gas leakage rate is ≤ 0.1%, which effectively reduces the risk of gas leakage;
High Reliability: The electrical life of the Circuit Breaker is 22 cycles, the mechanical life is ≥ 10000 cycles, with C2-E2-M2 tier model of linkage performance. The mechanical life of disconnector and fast earthing switch is 10000 cycles, and the fast earthing switch is solely designed with the characteristic of super class B;
Compact Structure: The three-phase common box connection method of the main bus, and the other three-phase individual box connection method, with the standard bay spacing is 2m and the minimum bay spacing is 1.8m;
The product is subject to lightning impulse test when leaving the Factory to completely eliminate the hidden danger of insulation discharge and ensure the stability and reliability of product quality.
Smart: The product is solely designed to be with the relevant sensor to realize the on-line monitoring and one key sequence control of the mechanical characteristics of the Circuit Breaker, gas, density, micro-moisture, partial discharge, etc.
