3-200 kv exchange non-clearane porcelain type zinc oxide lightning arrester, composite coat type metal oxide surge arrester (3.8-200 kv rated voltage) has began to send more multi-purpose series products, as listed in table 1.

3.8 228 kv ac rated voltage zero clearance porcelain type zinc oxide lightning arrester is used to protect the ac power transmission and transformation equipment from atmospheric overvoltage and operating over-voltage damage important protection of electric equipment is suitable for the family, the normal conditions of use:

, altitude does not exceed 1000 m;

Rated frequency is not less than 48 hz, no more than 62 hz;

Maximum wind speed, no more than 35 m/s;

Environment temperature is not higher than 40 °„ C, no less than to 40 °„ C;

Seismic intensity of 7, and the following areas;

For use in a specific environment (abnormal operating conditions) of arrester another development plateau, dirt resistant, resistant products.

Plateau type, can be used in high altitude 1000 m above sea level;

Fouling resistance type - the creepage distance is greater than 2.5 cm/kV, equivalence with cell density is equal to or greater than 0.03 mg/cm2 heavy polluted areas;

Used in seismic type
