Zinc oxide arrester passed short-circuit test

Haivo polymer housed zinc oxide surge arrester has passed the short- circuit test successfully in XIHARI again in 20^th of April 2021 (National quality supervision & inspection center for insulator & surge arrester).The Rated voltage of tested object is 36KV,Its nominal discharge current is 5kA.The tests have been performed in accordance with IEC 60099-4:2014 EDITION.Before tests,the tested objects was prepared by pre-failing method according to correlated standard and monitor enclosure was placed.Tests were be conducted three kinds of short circuit current, 20kA/0.2s, 12kA/0.2s, 6kA/0.2s, and 600±200A /1.0s. The test result is satisfied through evaluation by lab according to IEC 60099-4:2014.
