产品详情
The Wishpower 12kV lightning protection pin composite insulator is designed for medium-voltage overhead distribution systems. It combines conductor support, electrical insulation and lightning overvoltage protection in one compact unit. Its silicone rubber housing, high-strength insulating core and corrosion-resistant fittings help reduce flashover, arc damage and line tripping under thunderstorms, pollution, humidity and temperature variations.
Product Overview
A 12kV lightning protection pin composite insulator is installed on a crossarm or line support to secure the conductor, withstand mechanical loads and electrically isolate the energized conductor from grounded structures. Compared with a conventional pin insulator, the lightning protection version incorporates a controlled discharge path or protective electrode arrangement.
Key advantages of Wishpower composite insulators include:
High-temperature vulcanized silicone rubber housing with strong hydrophobic performance.
High mechanical strength for conductor loads, wind pressure and line vibration.
Controlled discharge or arcing structure to reduce direct arc damage to the insulation body.
Lightweight construction for easier transportation and pole-top installation.
Corrosion-resistant metal fittings for long-term outdoor service.
Customizable sheds, fittings, mounting dimensions and electrode arrangements.
Core Features
Combined insulation and lightning protection
The product performs the basic functions of conductor support and electrical isolation while improving protection against lightning impulse overvoltage.
Excellent pollution performance
The hydrophobic silicone rubber surface helps prevent the formation of a continuous conductive water film under rain, fog, salt contamination and industrial pollution.
Reliable mechanical strength
The insulating core and end-fitting connection are designed to withstand vertical conductor loads, transverse loads, wind deflection and operational vibration.
Controlled arc path
Properly arranged discharge electrodes or arcing fittings guide the arc away from the silicone housing and conductor connection area.
Lightweight construction
Composite insulation materials reduce product weight compared with equivalent porcelain units, simplifying handling and installation.
Strong environmental adaptability
The insulator is suitable for coastal regions, industrial zones, humid areas, high-UV environments and lightning-prone locations.
Reduced maintenance requirements
The non-brittle silicone rubber housing and hydrophobic surface help reduce cleaning and replacement frequency.
Product Structure
A typical 12kV lightning protection pin composite insulator consists of the following components:
Insulating core
A high-strength insulating rod or composite support body carries the main mechanical load and provides internal insulation.
Silicone rubber housing
The housing is molded around the insulating core to provide the required creepage distance and external insulation profile.
Conductor support section
The upper section supports and secures the overhead conductor through a conductor groove, tie arrangement or line clamp.
Lower mounting fitting
The lower metal fitting connects the insulator to the crossarm, bracket or pole-mounted support.
Discharge electrode
The electrode establishes a controlled discharge gap and defines the preferred discharge path during lightning overvoltage.
Arcing or protective fitting
This component guides the arc away from the main insulation body and reduces thermal damage.
Sealing interface
The interfaces between the core, housing and fittings are sealed to prevent moisture and contaminants from entering the internal structure.
