HY5(10)W-36 HY5(10)W-36J HY5(10)W-36L Surge Arrester
Description
The surge arrester is assembled above overhead distribution transformers, where they shunt the energy from over voltage events (especially lightning effects) to a ground connection and protect the equipment against damage in system.
Our lightning arresters are an important safeguard for power distribution systems as their role is to shunt the energy of an over voltage event to the ground connection. This means that when a lightning strike or other overvoltage event occurs, surge arresters can effectively divert excess energy away from equipment, preventing costly damage and downtime.
Lightning arresters are an important component of any overhead distribution transformer system as they are the first line of defense against the destructive power of lightning and other over voltage events. By absorbing and dissipating excess energy, it helps ensure the safety and reliability of the entire distribution network.
One of the main advantages of our lightning arresters is their robust construction and reliable performance. Our lightning arresters are designed to withstand the rigors of outdoor installations, providing long-term protection for overhead distribution transformers even in the harshest environmental conditions. With a durable housing and high-quality internal components, it provides distribution operators with superior reliability and peace of mind.

Feature
The zinc oxide surge 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 siliconcarbide 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.
