Product Description
Glass fiber pultruded cross arms are widely used in the construction of overhead power transmission and distribution lines.
They are commonly used in countries such as the United States, Canada, Australia, and Malaysia for their high strength, durability and resistance to corrosion.
They are also used in offshore wind farms for their high resistance to salt water corrosion.Glass fibercross arms pultruded tube are a popular alternative to traditional wooden and steel crossarms due to their lightweight, easy installation, and reduced maintenance costs.
Usually, the materials used for cross arms in transmission towers are wood, steel and glass fiber. Compared with the other two materials, the composition of glass fiber is larger. This is because glass fiber is non-conductive and has a higher mechanical strength to weight ratio. These characteristics make the glass fiber cross arm have great potential in replacing steel and wood cross arms.

This is because glass fiber is non-conductive and has a higher mechanical strength to weight ratio. These characteristics make the glass fiber cross arm have great potential in replacing steel and wood cross arms.
Traditionally, transmission tower structures use treated wood, steel or concrete as building materials. In recent years, the adaptability of glass fiber in cross arm production has been applied. This is because the surface of the glass fiber is smooth and firm, and the outer layer has a film, which can protect the inner surface of the Fiberglass Pultruded cross arm Power that may cause flashover.
