33kv gapless surge arrester/surge protective device (station type)

Zinc oxide compound sheath non-clearance surge arrester (short for arrestor) is used to protect the corresponding voltage-grade alternating current (AC) electric apparatus from the excess voltage.

1.excellent protective performance

The metal oxide resistor made have excellent volt-ampere characteristics, good response to steep front surge and high discharge capacity.
2.reliable pressure relief function
The unique pressure-relief device features precise operation, safely and reliablity which ensure metal oxide arrester to release internal excessive pressure in any event

3.unique sealing device

Execllent metal oxide arrester sealing is ensured during its service life by well elastic sealing gasket and unique sealing device
4.small size,light weight,easy installtion for the polymer housed arresters

5.polymer housed is made through direct injection molding and it enjoy high anti-tear intenstity,highly hydrophobic,anti-electric erosive and good aging properties.
