The core working elements of this series of products adopt polymetallic oxide powder, mainly zinc oxide. Therefore, this series of lightning arresters have good performance in such aspects as fast steep wave correspondence and chase capacity.

The products with gap adopt uniform gap irradiation, which reduces discharge dispersion and impact coefficient.
