Porcelain Surge Arrester

Introduction

 

Porcelain surge arresters are power system protection devices that prevent system failures caused by overvoltage surges. They are commonly used to protect high-voltage apparatus, transformers, and transmission lines. Porcelain surge arresters typically consist of metal-oxide varistors (MOV) encapsulated in porcelain housings. They are required to withstand high voltage and current stresses and to be capable of dissipating the energy generated by the surges. As a leading manufacturer in China, we produce high-quality porcelain surge arresters that are reliable, durable, and cost-effective.

Porcelain surge arrestor with metal Oxide is the most advanced over-voltage protection. It is used for protection of AC electrical power system, avoid from the atmosphere over-voltage and operating over-voltage damage. The core components using Zinc oxide barrier, compare with traditional silicon carbide arrester, it changed the characteristic of arrester, improve the flow capacity of over-voltage, so that make arrester changed fundamentally.
When the arrestor working under nominal voltage, only Microamp current flowing through the arrester. When encountered lightning hit, because of the nonlinear of ZnO barrier, thousands of amps current flow through the arrester at that moment, arrester under conduction status, release over-voltage energy, effectively limits the violations of over-voltage on the transmission and distribution equipment.
