  • Product Details
  • Company Profile

1. Small size, light weight, can be suspended installation, effectively saving floor space. 2. Good sealing performance, moisture-proof and explosion-proof, no explosion risk. 3. High mechanical strength, not easy to damage, easy to transport and installation. 4. Good hydrophobicity and strong pollution resistance.

Product Description

Polymeric housed metal oxide arrester of 10-35kv with release is equipped with special insulated backing plate and mounting support,upper bolt of release is connected with the bottom of arrester directly,and the lower bolt is connected with the earth wire.       

Release of arrester is aimed at automatic tripping when the arrester comes across failure,power frequency short-circuit current drives the release to operate,and earth terminal of release will trip automatically,so as to disconnect the failed arrester from the system ,operator should change it.In order to accomplish this object,the release must be featured with quick-acting characteristic and capability of withstanding prospective current impulse and operating duty.
