Product Description

Products Description

LW series pole mounted sf6 circuit breaker is a new outdoor switch developed by us. It has compact structure, complete functions. With high precision CT, zero sequence CT, zero sequence PT equipped, it has wide measuring range, high measuring precision, high reliability and stability, low power loss. It can correctly detect and judge various line failures. LW series pole mounted sf6 circuit breaker can be used with FTU to have intelligent functions, including measure, protect, control, signal, networking, online monitor and diagnose, precisely judge earthing point, measure line loss, failure wave record. It is suitable for 10kv overhead power distribution line and user branch circuit. It can immediately isolate failed sections, preventing user failure from spreading the whole power distribution line, avoiding power failure in large area. 

Features:

1. Simple structure, excellent arc extinguishing and insulation performance, low operation power, high rated data, long electrical life and maintenance free period. 
2. Switch enclosure is made of 304 stainless steel, lifelong corrosion proof.
3. High gas pressure relief valve to protect the switch body from cracks resulted from increased gas pressure caused by internal breakdown.
4. Low gas pressure lock and alarm device (optional), when the gas pressure in low in the circuit breaker, low pressure lock and alarm device can lock operation mechanism, thus the circuit breaker is more reliable.
