Product Overview
The 6kV export type composite housed metal oxide surge arrester from Wishpower is designed for overvoltage protection in medium-voltage distribution systems, equipment outlets and power distribution networks. Built with high-quality zinc oxide varistors and a silicone rubber composite housing, this arrester helps limit lightning overvoltage and switching overvoltage, protecting transformers, switchgear, cable terminals, motors and line equipment in demanding operating environments.
Wishpower 6kV export type composite housed metal oxide surge arrester is suitable for 6kV power systems where reliable overvoltage protection is required. It can be installed on distribution lines, substations, equipment outlet terminals and industrial power supply systems. Compared with traditional porcelain housed arresters, the composite housed design offers lighter weight, better pollution resistance and improved operational safety.
Key advantages include:
High-performance zinc oxide varistors with excellent nonlinear characteristics and low residual voltage.
Silicone rubber housing with strong hydrophobicity, UV resistance, aging resistance and pollution resistance.
Lightweight composite structure for easier transportation, installation and maintenance.
Reliable sealing design to reduce moisture ingress and improve long-term stability.
Gapless metal oxide design for fast and dependable overvoltage limitation.
Suitable for indoor, outdoor and polluted environments in medium-voltage distribution systems.
Core Features
Strong Overvoltage Protection
When lightning surges, switching surges or system faults generate abnormal voltage, the arrester conducts quickly and discharges surge current, limiting the voltage to a safe level for electrical equipment.Safe Composite Housing
The silicone rubber composite housing provides excellent anti-explosion and impact-resistant performance. It is safer than porcelain housing in outdoor substations, public distribution areas and export projects.Excellent Pollution and Weather Resistance
The polymer housing maintains stable insulation performance in coastal, humid, dusty and industrial pollution environments.Compact and Easy to Install
The 6kV composite housed metal oxide surge arrester is compact and lightweight. Mounting brackets, terminals and grounding accessories can be customized according to project requirements.Suitable for Export Projects
Wishpower can provide customized terminal structures, installation methods, packaging solutions and technical documents for overseas power projects and bulk procurement.
Product Structure
The 6kV export type composite housed metal oxide surge arrester mainly consists of:
