Product Overview
The 36kV polymer housed metal oxide surge arrester is designed to protect medium-voltage power systems from lightning overvoltage and switching overvoltage. Wishpower uses high-quality zinc oxide varistors and durable silicone rubber housing to ensure reliable insulation performance, pollution resistance, and long-term outdoor operation in demanding electrical environments.
Main advantages of Wishpower polymer housed surge arresters include:
High-quality zinc oxide varistors with low residual voltage and stable protection performance.
Silicone rubber housing with excellent hydrophobicity and pollution resistance.
Lightweight structure for easier transportation, installation, and maintenance.
Safer polymer housing design compared with traditional porcelain housed arresters.
Suitable for polluted, humid, coastal, mountainous, and renewable energy environments.
Core Features
Reliable Overvoltage Protection
The 36kV polymer housed metal oxide surge arrester responds quickly to lightning impulses and switching surges, effectively limiting voltage stress on electrical equipment.Excellent Pollution Resistance
The silicone rubber housing provides strong hydrophobic performance and hydrophobicity transfer, helping maintain insulation reliability under dust, salt fog, humidity, and polluted conditions.Stable Mechanical Strength
The internal structure and polymer housing are tightly integrated, offering good mechanical stability against vibration, bending stress, and long-term outdoor installation.Easy Installation and Maintenance
Compared with porcelain housed arresters, polymer housed arresters are lighter and easier to install, helping reduce installation time and maintenance costs.Wide System Compatibility
The product is suitable for distribution lines, substations, cable systems, wind farms, solar power plants, and industrial power distribution systems.
Product Structure
A 36kV polymer housed metal oxide surge arrester usually consists of the following components:
Zinc oxide varistors: The core protection element with excellent non-linear voltage-current characteristics.
Silicone rubber housing: Provides external insulation with aging resistance, UV resistance, and pollution flashover resistance.
Fiberglass reinforced support or insulation structure: Improves mechanical stability.
Top and bottom fittings: Used for electrical and mechanical connection, usually with hot-dip galvanized or anti-corrosion treatment.
Sealing system: Prevents moisture ingress and ensures long-term reliability.
Disconnector or surge counter interface: Optional accessories for fault isolation or operation monitoring.
