HY and Y series metal zinc oxide lightning arresters are suitable for limiting overvoltage in AC power systems with AC frequencies of 48-62Hz, 35KV and below. They are used to protect the insulation of various electrical equipment in the power system from lightning overvoltage or operational overvoltage damage, and are one of the important protective devices to ensure the safe operation of the power system.

Features: The metal zinc oxide lightning arrester uses zinc oxide resistors with excellent volt ampere characteristics as the core. Compared with traditional silicon carbide lightning arresters, it has the advantages of fast action, good steep wave characteristics, low residual voltage, large current capacity, no freewheeling, simple structure, light weight, high reliability, strong pollution resistance, and easy maintenance. The composite jacket type also features a silicone rubber integral molded jacket with no air gap, good sealing performance, moisture and explosion resistance, and no risk of explosion, making it particularly suitable for use in switchgear.
The main technical performance of this product complies with the provisions of GB11032-2000 and JB/T8952-1999 standards.
