Their materials directly determine the safety and reliability of the wires. Traditional iron-porcelain cross arms have experienced matching problems after years of use. In transmission projects, cross arms support insulators and wires. Compared with traditional iron-porcelain crossarms, they have eight advantages. With the development of composite materials, FRP cross arms and cross braces are now widely used.
Capable of resisting damage caused by lightning strikes, enhancing safety.
1.Great insulation
FRP is a natural insulating material. Unlike steel cross-arms, it needs no extra insulating parts. It can prevent damage from lightning and make power lines safer.
FRP materials exhibit excellent corrosion resistance when used.
2.Strong anti-corrosion ability
FRP resists acid and alkali. It will not rust or corrode even in wet and heavily polluted industrial areas, so it lasts much longer.
Approximately one-quarter of the weight of other materials is utilized for convenience.
3.Light weight
FRP weighs only about one quarter of steel and porcelain. It cuts labor costs during transport and installation.
After installation, FRP cross braces can significantly reduce maintenance costs.
4.Low maintenance cost
You hardly need to maintain FRP cross-arms after installation. Power companies can save a lot on repairs in the long run.
The mechanical performance of low-temperature cyclic working conditions remains highly stable.
5.Stable performance in cold weather
FRP keeps good mechanical performance at low temperatures. It will not break or fall off.
FRP cross members exhibit high impact resistance and are unlikely to fracture or fall off.
6.Strong impact resistance
FRP cross-arms can stand hard hits. They do not crack or drop when hit by external force, and reduce outdoor safety risks.
Thermal expansion testing of FRP materials demonstrates excellent structural deformation resistance and safety performance.
7.No easy deformation
FRP has low thermal expansion. Its structure stays stable after long-term use and remains safe.
The material used for FRP cross braces can be recycled and reprocessed.
8.Recyclable
We can recycle and reuse old FRP cross-arms. They meet the green construction standards for carbon reduction.
These are the eight advantages of the FRP cross-arm.
FRP cross brackets also have the above eight advantages. They fix many weaknesses of traditional steel and porcelain cross brackets. They improve the safety of power lines and reduce overall costs throughout their service life. FRP cross-arms and cross brackets will be the main development direction for power transmission lines.
