产品详情
Wishpower 36kV composite sheath metal oxide surge arrester is designed for 36kV AC power systems. It protects transformers, switchgear, cable terminals, overhead lines and substation equipment from lightning overvoltage and switching overvoltage.
Compared with traditional porcelain housed arresters, the composite sheath design offers better safety, easier handling and improved adaptability for outdoor power networks.
Main advantages include:
High-performance zinc oxide varistors with excellent nonlinear characteristics and low residual voltage.
Silicone rubber composite housing with good hydrophobicity, pollution resistance and anti-aging performance.
Lightweight polymer housing, reducing transportation and installation risks.
Suitable for outdoor environments such as humid areas, polluted areas, coastal regions and high UV exposure locations.
Compact structure with reliable sealing performance for long-term operation.
Available with different installation accessories for pole-mounted, substation and equipment protection applications.
Core Features
Reliable Overvoltage Protection
The zinc oxide varistor works as the core protection element. It remains highly resistive under normal operating voltage and quickly conducts surge current during overvoltage events.Durable Composite Sheath
The silicone rubber housing provides excellent hydrophobicity and pollution flashover resistance, making the arrester suitable for long-term outdoor use.Low Residual Voltage
The arrester effectively limits lightning and switching overvoltage, reducing insulation stress on protected equipment.Lightweight Design
Compared with porcelain housed arresters, the composite sheath arrester is lighter and easier to transport, handle and install.Excellent Sealing Performance
The sealed structure prevents moisture and contaminants from entering the internal components.Wide Application Range
It can be used for distribution lines, overhead lines, substations, transformers, cable terminals and outdoor switchgear.Low Maintenance Cost
The stable structure and weather-resistant materials help reduce routine maintenance requirements.
Product Structure
A 36kV composite sheath metal oxide surge arrester is generally composed of the following parts:
Zinc Oxide Varistor Blocks
The core protection components that discharge surge current and limit residual voltage.Silicone Rubber Composite Housing
Provides external insulation, weather resistance, pollution resistance, UV resistance and hydrophobic performance.Fiberglass Reinforced Support Structure
Provides mechanical support and structural strength for outdoor operation.Metal End Fittings
Used for electrical connection and mechanical installation, usually with corrosion-resistant treatment.Sealing System
Prevents moisture, water and contaminants from entering the internal structure.Optional Disconnector or Surge Counter
Disconnectors, surge counters or monitoring devices can be supplied according to project requirements.
