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.
The 66KV power station type arrester adopts zinc oxide resistor, which has excellent nonlinear volt-amperage characteristics. It has the advantages of good steep slope response, no delay to steep slope voltage, operating residual low, no discharge dispersion and so on. These characteristics make the protection margin of the arrester greatly improved under steep slopes, lightning waves and operating waves, and improve the reliability of protection.

1. Moisture-proof and explosion-proof: the whole molding, good sealing performance, special structure, can effectively moisture-proof and explosion-proof ;
2. Good heat dissipation: has a large overvoltage absorption capacity, can work stably in high temperature environment ;
3. Small size, light weight: flexible installation collision resistance, high tensile strength, transport without damage ;
4. Wide range of application : most suitable for installation in the transmission line with low lightning resistance level and high lightning trip rate; Arid hills and mountains with little rain; High ground resistance pole tower, long span river pole tower; Where the operating overvoltage is high and it is necessary to restrict access to the substation; Seriously polluted area .
1. The ambient temperature is -40 ° C~40° C.
2. The altitude does not exceed 2000m(plateau areas should be explained when ordering)
3. The power supply frequency is 48-62HZ.
4. The maximum wind speed does not exceed 35m/s.
5. Earthquake intensity below 7 areas.
6. Long-term applied to the power frequency voltage on the arrester does not exceed the arrester continuous operation voltage.
