ZFW43-126(L)/ T3150-40气体绝缘金属封闭开关设备

Common Feature

Self-compression arc quenching interrupter + Spring mechanism

Circuit breaker arc quenching is through the new self can interrupter and simulation of electromagnetic flow field calculation and design, breaking performance, equipped with new spring operating mechanism, simple and reliable operation.

Three-position switch

Three-position switch, is about isolation and earthing switch into one, and share an operating mechanism, not only simplifies the product structure, so that significantly reduced dimensions, but also to achieve a mechanical interlock between isolating switch and grounding switch, and improve the reliability of the product to run.

Integrated earthing switch

Switch body with spring actuator with integrated design, effectively simplifying the structure, reducing the dimensions. At the same time either electric actuator operation, but also can be manually operated, and a mechanical interlock, improve the reliability of the product to run.

Small size, light weight

Products for the three-phase box-type structure, typical interval size: 4000 × 800 × 3000mm, weight typical interval: less than 3000kg. Gap width of only 0.8m, 1m intervals arranged according greatly saves floor space, floor space to meet the requirements of urban substations and other occasions increasingly demanding requirements.
