Introduction to Composite Crossarms


Composite insulating crossarms are crossarms made of composite materials such as fiberglass reinforced polymer (FRP). They are innovative components on power transmission poles that offer advantages not found in traditional wooden cross arms.

Composite insulated cross arms are made of environmentally friendly materials that are recyclable and biodegradable. They have excellent weather resistance, corrosion resistance and abrasion resistance, providing strong support in harsh weather conditions. They are more durable and require less maintenance than traditional wooden cross arms.

One of the main advantages of composite insulated cross arms is their higher strength-to-weight ratio. They have a greater load-bearing capacity than wooden cross arms while being lighter than steel cross arms, making them easier to install at high altitudes and other hard-to-reach locations. This also reduces shipping costs.

Composite insulated cross arms have good insulation properties and can avoid radio frequency interference caused by farm animals and humans. They have low dielectric constant and relatively high breakdown voltage, ensuring the reliability and stability of power transmission and distribution systems.

In terms of structural installation, composite insulated cross arms are simple and reliable to install. They can be supported using conventional systems and are easily installed and adjusted using specific tools and fixings. They can also be used in power lines of different high voltages.

Composite insulated cross arms are increasingly favored by power companies due to their extreme durability and better insulation configuration in high-risk environments, and are a popular option in modern power transmission networks.
