M.V. Polymer Lightning Arresters are used to protect transformers and other equipments in station and distribution systems against the damage by atmospheric (especially lightning effects) and operational conditions.
Oxides of metals Without gaps, the purpose of lightning arresters is to shield energy systems from potential harm during regular surges, without compromising normal operating voltage. The unique quality of gapless arresters stems from the non-linear properties of metal-oxide varistors in the voltage and current scales. The non-linear characteristic is significantly greater than that of silicon carbide lightning arresters.

PRODUCT FEATURE

The zinc oxide lightning arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with the conventional silicon carbide arrester, this prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through- current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arresters.
