FRP cross arm Crossarm introduction The glassfiber composite materials product(FRP) crossarm developed by our company, had applied the national patent(Patent No. 03212387.6). This product has save energy, light weight, high strength, and good quality on impact, dielectric, corrosion retardancy, heat retardancy and so on properties. Those good properties are excelled wooden and iron crossarm. Power-frequency withstand voltage, leakage current, bending load etc. indexes are satisfied the following technique conditions. JB/T9676-1999high-voltage line porcelain crossarm insulator, GB13398 insulated pole used under electric condition, and GB/T775.3/1987 insulator test method. Now our products had been used at Shenyang and Hebei and so on lines.
