الوصف

Overview

The polymer-housed lightning arresters feature a polymer and composite material housing, with a single-column or multi-column resistor disc column as the core. They cover voltage ratings from 10kV-1000kV AC and ±0.75kV-±1100kV DC.

Features

Excellent Insulation Performance and Aging Resistance

Rigorously selected materials and strict adherence to technical requirements ensure strength, precision, and improved insulation performance and lifespan.

High Dielectric Strength

High-quality insulation materials maintain stable insulation under high voltage conditions.

Strong Contamination Resistance

The surface exhibits hydrophobicity and self-cleaning capabilities, effectively resisting contamination adherence and corrosion, maintaining cleanliness and stable insulation performance.

Lightweight and Compact Structure

Reasonable structural design and lightweight materials result in a lighter weight and smaller volume compared to traditional porcelain-housed lightning arresters.
