产品详情
The 27kV pin type composite insulator is designed for high-voltage overhead distribution lines, providing reliable conductor support, electrical insulation and mechanical stability. Compared with traditional porcelain insulators, Wishpower 27kV pin type composite insulators use silicone rubber housing and high-strength fiberglass core technology, offering lightweight structure, excellent anti-pollution performance, strong weather resistance and easy installation. It is suitable for urban distribution networks, rural power grids, industrial power supply lines and outdoor power systems operating in demanding environments.
Wishpower 27kV pin type composite insulator is developed for medium and high-voltage overhead distribution systems. It provides stable insulation support for 27kV power lines and helps improve the safety and reliability of distribution networks.
The product is manufactured with an integrated molding process, allowing the silicone rubber sheds, housing, fiberglass core and metal fittings to form a compact and reliable structure. This design helps reduce moisture ingress, interface discharge and long-term aging risks.
Main advantages include:
High-temperature vulcanized silicone rubber housing with excellent hydrophobicity.
High-strength epoxy fiberglass core for stable mechanical performance.
Lightweight structure for easier transportation and installation.
Hot-dip galvanized metal fittings for improved corrosion resistance.
Suitable for polluted, humid, coastal, mountainous and rural power line environments.
Customizable creepage distance, connection size and fitting design.
Core Features
Excellent Electrical Insulation Performance
The 27kV pin type composite insulator provides reliable insulation performance for overhead power distribution systems, helping reduce flashover risk and improve line safety.Strong Anti-Pollution Capability
Silicone rubber material offers excellent hydrophobicity and pollution resistance, making the insulator suitable for humid, dusty, coastal and contaminated environments.Stable Mechanical Strength
The fiberglass core provides high bending and tensile strength, allowing the insulator to withstand conductor load, wind load and operational vibration.Lightweight Design
Compared with porcelain pin insulators, composite insulators are lighter and easier to handle, helping reduce installation time and tower load.Excellent Aging Resistance
The silicone rubber housing offers good resistance to UV radiation, ozone, temperature changes and electrical erosion, supporting long-term outdoor operation.Low Maintenance Cost
The product is resistant to breakage and impact, reducing transportation damage, installation loss and maintenance frequency.
Product Structure
Wishpower 27kV pin type composite insulator mainly consists of the following parts:
Silicone Rubber Sheds
The sheds increase creepage distance and improve insulation performance under rain, pollution and humid conditions.Silicone Rubber Housing
The housing protects the fiberglass core from moisture, aging, electrical erosion and environmental damage.Epoxy Fiberglass Core
The fiberglass core works as the main load-bearing component and provides stable mechanical strength.Metal End Fittings
The fittings are used for installation and connection with crossarms or supporting structures. Hot-dip galvanized steel is commonly used for corrosion resistance.Sealing System
The end sealing structure prevents moisture from entering the interface between the core and fittings, improving long-term operating reliability.
