Certified 36kV Polymer-Housed Surge Arrester for MV Distribution Lines

A high-performance, maintenance-free solution designed to protect 36kV medium voltage distribution lines and connected electrical cables from lightning strikes, switching surges, and temporary overvoltages. Engineered with a silicone rubber housing for superior environmental resistance, this arrester features a high-energy zinc oxide (ZnO) varistor core, ensuring reliable operation for up to 50 years in coastal, desert, and high-altitude environments.

1. Product Overview & Key Features

Feature	Description	Benefit
Core Protection	Zinc Oxide (ZnO) Varistor technology with 100kA (4/10µs) high current impulse withstand.	Provides extremely fast (nanosecond) response to clamp dangerous overvoltages, safeguarding power cables and sensitive equipment.
Robust Housing	Polymer-housed with silicone rubber, featuring a 1,082mm creepage distance for Pollution Level IV.	70% lighter than porcelain, non-fragmenting, and ideal for coastal grids (salt fog) and industrial/desert pollution.
Safety & Monitoring	Integrated disconnecter with visual failure indicator. Explosion-proof design (non-fragmenting).	Enhances grid safety, allows for easy fault identification from the ground, and prevents collateral damage.
Global Compliance	Certified to IEC 60099-4, ANSI/IEEE C62.11, and GB/T 11032.	Guarantees performance and reliability for international projects and MV distribution networks.
