Product descriptions from the supplier
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.

Research on Arcing and Interruption Characteristics of Eco-Friendly Gas-Insulated Ring Main UnitsEco-friendly gas-insulated ring main units (RMUs) are important power distribution equipment in electrical systems, featuring green, environmentally friendly, and high-reliability characteristics. During operation, arc formation and interruption characteristics significantly affect the safety of eco-friendly gas-insulated RMUs. Therefore, in-depth research on these aspects is of great significance for ensuring the safe and stable operation of power systems. This article aims to investigate the a12/10/2025 -
SF6 vs SF6 gas Free Ring Main Units: Key DifferencesFrom the perspective of insulation performance, sulfur hexafluoride SF6 exhibits excellent insulating properties. Its dielectric strength is approximately 2.5 times that of air, effectively ensuring the insulation performance of electrical equipment under standard atmospheric pressure and ambient temperature. The new SF6 gas free gases used in SF6 gas-free switchgear—such as certain gas mixtures—can also meet insulation requirements, though their specific values vary depending on the formulation12/10/2025 -
High-Voltage SF₆-Free Ring Main Unit: Adjustment of Mechanical Characteristics(1) The contact gap is primarily determined by insulation coordination parameters, interruption parameters, contact material of the high-voltage SF₆-free ring main unit, and the design of the magnetic blowout chamber. In practical application, a larger contact gap is not necessarily better; instead, the contact gap should be adjusted as close as possible to its lower limit to reduce operating energy consumption and extend service life.(2) The determination of contact overtravel is related to fac12/10/2025 -
How to Monitor Partial Discharge in RMUs Safely？Insulation degradation in power equipment is generally caused by multiple factors. During operation, insulation materials (such as epoxy resin and cable terminations) gradually deteriorate due to thermal, electrical, and mechanical stresses, leading to the formation of voids or cracks. Alternatively, contamination and moisture—such as dust or salt deposition or high-humidity environments—can increase surface conductivity, triggering corona discharge or surface tracking. Additionally, lightning s12/09/2025 -
