Product Description

Product Description

PRFV Flame retardant crossarms

Glass fiber reinforced plastic (GRP) crossarm, also known as fiberglass crossarm, is a structural component widely used in power transmission and distribution systems. It is fabricated from thermosetting resin and glass fiber reinforcement, which gives it excellent mechanical and electrical properties.

 

The production process of GFRP crossarms involves several steps, including mold-making, resin impregnation, curing, and finishing. First, the mold is fabricated according to the desired shape and size of the crossarm. Then, glass fiber mat or cloth is cut to size and laid into the mold. The mold is then vacuum-sealed and resin is introduced through small holes. The resin impregnates the glass fiber and fills the voids between the fibers, creating a solid composite. The mold is then heated to cure the resin and form the PRFV crossarm.

Product advantage

One of the key advantages of GFRP Power Cross arms is their long service life. They have a low coefficient of thermal expansion, which reduces the risk of cracking or warping due to temperature changes. They are also highly resistant to weathering, such as sun exposure and harsh winds. Additionally, they require minimal maintenance, which reduces downtime and improves reliability.    

structural PRFV crossarms are available in various sizes and shapes to accommodate different applications. They can be customized to meet specific requirements, such as increased strength or stiffness for high load applications. They can also be designed to have tapered ends, which reduces wind drag and improves the aerodynamics of transmission lines.

 

Solid / hollow cross arms
Polyurethane foam filling	No polyurethane foam filling
Improve the rigidity of the cross arm	Weaker hardness
Prevent plastic deformation	Easy to deform

Product Application

FRP insulator crossarms are used in a variety of environments due to their corrosion resistance, UV resistance, and high strength-to-weight ratio.
They are commonly used in coastal regions, where salt air and moisture can cause corrosion of metallic components. They are also used in areas with seismic activity, as they have low mass and high stiffness, which reduces the risk of damage during earthquakes. Additionally, their light weight makes them easier to transport and install, reducing costs and improving safety.
