12KV 10kA Polymer Surge Arrester

  • Model YH10W-12

M.V. Polymer Surge 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 Gapless surge arresters are intended to stop potential harm from occurring in the event of common energy system surges, without affecting the system at normal operation voltage. Due to the non-linear properties of metal-oxide varistors between the voltage and current scales, gapless arresters have this unique feature. When compared to silicon carbide surge arresters, the non-linear feature is significantly greater.

PRODUCT FEATURE

The most sophisticated over-voltage protection available today is the zinc oxide lightning arrester. Because zinc oxide arrester is the primary resistor disc used in the core component. In contrast to the traditional silicon carbide arrester, this product's prescription significantly enhances the resistor disc's volt-ampere characteristics and boosts its through-current capabilities at over-voltage, resulting in significant local modifications to the arresters' characteristics.
