YH5WX-51/134 line type lightning arrester is a kind of lightning arrester specially designed for AC power transmission and transformation lines, aiming at limiting the line lightning overvoltage, improving the line lightning resistance level, and reducing the tripping rate caused by lightning strike. The arrester is mounted by suspension, usually connected in parallel at both ends of line insulators, suitable for 35kV voltage class transmission line.

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.
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.
