What Are The Structural Performances Of Composite Cross-arm Insulators

1. The umbrella disk made of high molecular polymer with silicone rubber as the matrix has the advantages of good hydrophobicity, corrosion resistance, aging resistance, etc. It can effectively prevent the occurrence of flashover accidents, reduce manual cleaning, and avoid zero value maintenance, providing a reliable guarantee for the safe operation of the transmission line.

2. The core rod is made of glass fiber reinforced resin rod, which has a very high tensile strength (>1100Mpa), which is about 1.5 to 2 times that of ordinary steel and 3 to 5 times that of high-strength porcelain. In addition, the core rod also has good vibration reduction, creep resistance and fatigue fracture resistance.

Cable lugs can effectively use narrow corridors to open voltage and transmit electricity, which is suitable for urban network technical transformation, can reduce the height of poles and towers, and can save a lot of manpower, material and financial resources. Due to its high bending strength, it can prevent the level chain breakage accident that is easy to occur in the cross arm, and is an ideal porcelain cross arm replacement product. The composite cross arm insulator is small in size, light in weight, strong in shock and impact resistance, and does not require manual cleaning, providing a guarantee for safe operation.
