Product Description

 

Company Profile

Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable power equipment manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations, high-voltage switches, and medium and low voltage complete sets of equipment. The equipment put into production and operation of the project advocates energy saving, intelligence, informatization, and mechanization. The company has established the Henan Triangle Energy-saving Transformer Engineering Technology Research Center, with 71 utility model patents and 15 invention patents. With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa, and other regions, covering more than 40 countries.

GW5-126 isolation switch is a three-phase AC 50Hz outdoor high-voltage AC electrical appliance, used for rated voltage 110kV power system, for high-voltage lines in the no-load situation to switch lines and maintenance of high-voltage bus, circuit breakers and other electrical equipment and live high-voltage lines for electrical isolation. It provides the inspected equipment and maintenance personnel with a visible insulation distance that meets the requirements to ensure the safety of maintenance personnel.
It complies with GB1985 and IEC62271-102 standards.
