LW57-252/Y4000-50 Tank SF6 Circuit Breaker

The model LW57-252/Y4000-50 tank SF6 circuit breaker is a product with independent intellectual property right. It is three-phase electrical linkage-type circuit breaker with split-phase structure. The use of advanced arc extinguish chamber gives it a downsized structure, which significantly improves electrical and mechanical property of the product. It has advantages such as reliable performance, advanced technology, compact structure, less operating power, long service life, easy maintenance and excellent anti-seismic property.

Performance features

1. It consists of three poles which can be operated individually and one control cubicle. The poles of each circuit breaker are driven by a spring operating mechanism to realize single-pole or three pole electric linkage operation.

2． It adopts advanced single-break structure with small mixed pressure arc extinguishing chamber, which excels in arc extinguishing capacity and requires less power consumption.

3．By using small mixed pressure arc extinguish chamber, it needs less gas consumption. It has small volume, attractive appearance and small floor coverage, and is easy for installation.

4．The single pole is equipped with internationally advanced ABB HMB-2.8 hydraulic spring operating mechanism from Germany, which employs modular design, compact in structure, small in transmission, and low in noise protection.

5．With advanced technology, compact structure, low center of gravity in the break, small power consumption, it excels in seismic performance, a second-to-none high-voltage switchgear product for earthquake prone areas.

6．The product is equipped with domestic advanced electronic current transformer, which can provide high-precision signals for metering and protective systems of substations.
