Product Overview
The Wishpower 10kV long rod composite suspension insulator is designed for conductor suspension, tension connection and electrical insulation in overhead distribution lines. It combines a high-strength fiberglass core, silicone rubber housing and corrosion-resistant end fittings, offering reliable mechanical performance, pollution resistance, lightweight construction and convenient installation for demanding outdoor power systems.
Product Overview
The 10kV long rod composite suspension insulator is an electrical and mechanical component used between energized conductors and supporting structures in 10kV overhead lines. It provides the required insulation distance while carrying conductor tension, dead weight, wind load, vibration and other mechanical forces.
Wishpower manufactures composite suspension insulators with different mechanical ratings, creepage distances, housing profiles and end-fitting combinations. The product can be configured for distribution networks, industrial power lines, renewable energy projects and overhead line renovation.
The main advantages include:
High-strength fiberglass reinforced epoxy resin core.
Hydrophobic silicone rubber housing and sheds.
Lightweight construction for easier transport and installation.
Optimized shed profile for different pollution conditions.
Multiple end-fitting options for line hardware compatibility.
Suitable for new overhead lines and insulator replacement projects.
Core Features
Reliable Electrical Insulation
The optimized insulation distance and shed profile help the insulator withstand power-frequency voltage, lightning impulse voltage and surface discharge.High Mechanical Strength
The internal FRP core carries the primary tensile load and provides mechanical support for conductor suspension and tension applications.Pollution Flashover Resistance
The hydrophobic silicone rubber surface reduces the formation of continuous conductive water films under humid, dusty or saline conditions.Lightweight and Easy to Install
Compared with conventional porcelain insulators, the composite design reduces handling weight and simplifies installation on poles and towers.Outdoor Weather Resistance
The housing is designed to withstand ultraviolet exposure, rain, ozone, temperature variation and long-term outdoor service.Flexible End-Fitting Configurations
Ball, socket, eye, clevis, tongue and other fitting combinations are available to match suspension clamps, tension clamps and tower hardware.Suitable for Various Environments
The product can be used in urban distribution networks, rural power lines, industrial areas, wind farms and solar power projects.
Product Structure
A typical 10kV long rod composite suspension insulator consists of the following components:
FRP Core Rod
The fiberglass reinforced epoxy resin core is the main load-bearing component and provides high axial tensile strength.Silicone Rubber Housing
The housing covers the core rod and provides electrical insulation, environmental protection and sealing.Composite Sheds
The sheds increase the creepage distance and improve surface insulation performance. Shed diameter, spacing and profile can be optimized for specific pollution levels.Metal End Fittings
End fittings connect the insulator to conductors and supporting structures. Common options include ball, socket, eye, clevis and tongue fittings.End-Sealing System
The interface between the core rod, housing and metal fittings is sealed to reduce the risk of moisture penetration.Optional Protective Accessories
Arcing horns, grading devices or other protective fittings can be supplied when required by the line design.
