Product Overview
The 10kV pin type composite insulator is widely used in overhead distribution lines to support conductors and maintain safe insulation between the conductor and pole structure. Wishpower 10kV pin type composite insulator is manufactured with a silicone rubber housing, fiberglass core rod and metal end fittings, making it suitable for urban networks, rural distribution lines and standard 10kV overhead power systems.
Wishpower 10kV pin type composite insulator is designed for medium-voltage distribution systems. It provides conductor support, electrical insulation and stable line operation in outdoor environments. Compared with traditional porcelain pin insulators, composite pin insulators offer advantages in weight, pollution resistance, impact resistance and installation efficiency.
Main product advantages include:
High-temperature vulcanized silicone rubber housing with excellent hydrophobicity.
High-strength epoxy fiberglass core rod for stable mechanical performance.
Reliable connection between metal fittings and the core rod.
Lightweight structure for easier transportation and installation.
Suitable for polluted, humid, coastal and outdoor environments.
Custom options available for creepage distance, dimensions, fittings and mechanical strength.
Core Features
Reliable Electrical Insulation
The 10kV pin type composite insulator provides stable insulation performance for medium-voltage overhead distribution lines.Excellent Anti-Pollution Performance
The silicone rubber sheds offer strong hydrophobicity, helping reduce flashover risk in dusty, humid or polluted areas.Lightweight and Easy to Install
Compared with porcelain insulators, composite insulators are lighter and easier to handle during field installation.Good Impact Resistance
The composite structure reduces the risk of brittle fracture during transportation, installation and operation.Stable Aging Resistance
The silicone rubber housing provides resistance to UV radiation, ozone, temperature variation and outdoor weathering.Low Maintenance Cost
The hydrophobic surface helps reduce contamination accumulation and lowers routine maintenance requirements.
Product Structure
A 10kV pin type composite insulator normally consists of the following parts:
Silicone Rubber Housing and Sheds
Provides external insulation, increases creepage distance and improves anti-pollution performance.Epoxy Fiberglass Core Rod
Acts as the main mechanical load-bearing component and provides bending and tensile strength.Metal End Fittings
Usually made of hot-dip galvanized steel or customized metal fittings for connection with crossarms or pole structures.Sealing Area
Prevents moisture ingress into the connection between the core rod and metal fittings.Conductor Supporting Groove or Top Structure
Used to support and fix the conductor in the required operating position.
