Composite Insulators

Overview

Composite insulators are a modern type of electrical insulator made from

composite materials, typically consisting of a non-ceramic core (like fiberglass

or polymer) combined with an insulating sheath made from advanced

materials such as silicone rubber or epoxy.

Product Types

Application

High-Voltage Transmission Lines: Composite insulators are commonly used in

high-voltage and extra-high-voltage transmission systems due to their

superior performance in challenging environmental conditions.

Distribution Networks: They are also used in distribution lines, particularly in

areas prone to salt pollution or other environmental challenges.

Renewable Energy Projects: Composite insulators are used in the

construction of solar or wind farms' electrical systems, where durability and

light weight are important.

Urban and Coastal Areas: Due to their resistance to corrosion and pollution,

composite insulators are often used in cities and coastal regions where

traditional insulators might degrade faster.

Key Features of Composite Insulators:

Materials:The core is typically made of fiberglass or polymer, which provides

mechanical strength and flexibility.

The outer sheath is often made from silicone rubber, EPDM (ethylene

propylene diene monomer), or other synthetic materials that offer excellent

electrical insulating properties and resistance to environmental factors.

Lightweight: Composite insulators are much lighter than traditional porcelain

or glass insulators, which makes them easier and cheaper to transport and

install.

Corrosion-Resistant: Unlike porcelain or glass insulators, composite

insulators do not suffer from rust or corrosion, making them ideal for use in

coastal areas or harsh environments.

High-Performance in Harsh Conditions: These insulators perform well in

extreme weather conditions, including high humidity, salt fog, and polluted

environments. The materials used are resistant to contamination and

contamination-related issues like electrical tracking.

Long Service Life: Composite insulators have a long service life, thanks to

their resistance to environmental wear and tear. The outer insulating material,

such as silicone rubber, is highly resistant to UV degradation and aging.

Hydrophobic Surface: The silicone rubber used for composite insulators

typically has a hydrophobic surface, meaning it repels water, reducing the risk

of tracking and electrical leakage caused by moisture.

Safety and Compliance

Testing methods and equipment is critical in ensuring that insulators meet the stringent requirements for electrical performance, mechanical integrity, and environmental resilience.

Every product needs to go through many rigorous tests to ensure that each one delivered to our customers are qualified and conform to standard.
