FRP CROSS ARM
process custom-made frp pultruded FRP cross arm
Our company developed advanced glass fiber composite products cross-arm, has applied for a national patent (patent number: 03212387.6) . The product has the advantages of light weight, good specific strength, impact resistance, excellent dielectric properties, corrosion resistance and good heat resistance. According to the relevant standards, the indexes of power frequency withstand voltage, leakage current and bending failure load are all satisfied: the size characteristics of JB/T8179-1999 porcelain cross-arm insulators for high voltage lines, and the technical conditions of JB/T9676-1999 porcelain cross-arm insulators for high voltage lines, general Specification for insulating Poles for live working. The utility model solves the shortcomings of the existing wooden cross arm and the iron cross arm, such as poor anticorrosion performance, poor flame retardant performance, low strength, poor insulation performance, large energy loss and short service life.
