Product Description

QDW3 series universal Air circuit breaker(hereinafter referred to as breaker)is suitable for the circuit of AC 50Hz with rated voltage 400V, 690V and rated current up to 6300A. It is mainly used to distribute electric energy and protect circuits and power-supply equipment from overload, under-voltage, short-circuit and single-phase earthing. with intelligentized and selective protection functions, the breaker can improve the reliability of power supply, and avoid unnecessary power failure. The breaker is applicable for power stations, factories, mines(for 690V) and modern high-buildings, especially for the distribution system of intelligentized building. This breaker conforms to IEC60947-2 and GB14048.2 and CE.

High overload distribution transformers
Product overview
In recent years, with the increasing mobility of the population, the hot season, and distribution transformers in rural areas during the Spring Festival period of severe overload short run problem of rural electricity appears. In order to solve such problem of electricity, the company response to the State Grid  Corporation of China in recent years advocated actively develop rural power distribution transformers and high overload capacity application work, we developed a high overload capacity distribution transformers.
High overload capacity integrated rural power distribution transformer station area based on typical load characteristics, high overload distribution transformer overload performance will meet the 1.5 times the rated capacity  of six hours, 1.75 times the rated capacity of 3 hours, 2.0 times the rated capacity of one hour of continuous operation stage design requirements, and does not affect the normal life of the
