Product Overview
The 35kV line post composite insulator is an important insulation and support component for overhead power transmission and distribution lines. Wishpower designs this product with silicone rubber housing, fiberglass core rod and durable metal end fittings, providing stable performance for long-term 35kV line operation.
Main advantages include:
High-temperature vulcanized silicone rubber housing with excellent hydrophobicity.
Epoxy fiberglass core rod for reliable mechanical strength.
Lightweight structure for easier transportation, installation and maintenance.
Suitable for polluted, humid, coastal and outdoor environments.
Customizable creepage distance, fitting dimensions and installation structure.
Core Features
Reliable electrical insulation
Designed for 35kV power systems, helping reduce flashover risks and improve line safety.Excellent anti-pollution performance
Silicone rubber housing provides strong hydrophobicity, making it suitable for industrial, coastal and dusty areas.Stable mechanical strength
The fiberglass core rod offers strong resistance to bending, tensile load and line vibration.Lightweight and easy to install
Compared with porcelain insulators, composite insulators are lighter and easier to handle during construction.Good aging resistance
The housing material offers resistance to UV radiation, electrical erosion, tracking and weather aging.Lower maintenance cost
The product is not easy to break and has good pollution resistance, reducing cleaning and replacement frequency.
Product Structure
The 35kV line post composite insulator usually consists of the following parts:
Silicone rubber housing
Provides external insulation, creepage distance and pollution flashover resistance.Epoxy fiberglass core rod
Acts as the main load-bearing part and ensures mechanical stability.Metal end fittings
Usually made of hot-dip galvanized steel or customized corrosion-resistant fittings for connection with crossarms, brackets or conductor hardware.End sealing system
Prevents moisture from entering the interface between the core rod and end fittings.Shed profile
Optimized shed design improves self-cleaning performance and insulation reliability in polluted environments.
