BEIKAI ZFW31-126 Mixed Gas Insulated Metal Enclosed Switchgear

Product Description: The ZFW31-126 mixed gas insulated metal sealed switchgear circuit breaker adopts advanced self energy breaking technology. Except for the circuit breaker, the three position switch, current transformer, wire and other components use a mixture of 70% nitrogen and 30% sulfur hexafluoride gas as the insulation medium. By applying electric field simulation and thermoelectric coupling simulation techniques combined with laboratory data, the insulation structure and current conduction structure of the product are designed to ensure the insulation performance and capacity requirements of the product. The GIS rated current for mixed gas insulation is 3150A, and the short-circuit breaking current is 40kA.
