YH5W Silicone-housed Live-line Surge Arresters

YH5W live-line surge arresters offers uninterrupted protection of overhead equipment and transmission lines against lightning.

BENEFIT
Each of our surge arrester is manufactured with the utmost care and undergoes rigorous testing according to accreditation standards.
YH5W live-line surge arresters are drop out arresters which can be efficiently replaced with the help of link stick. No outages are needed for maintenance.
YH5W live-line surge arresters are equipped with arrester disconnector which disconnects the arrester from the system in the event of device failure, thus preventing a persistent fault on the system and giving visual indication of the failed arrester.
Unique and patented design offers other benefits such as easy installation, repelling birds and snow accumulation, and the capability of working in severe pollution conditions.
