composite insulator

1. It has good resistance to soiling and frees of maintenance. The hydrophobic mobility of silastic makes the surface of insulator with dirt retention have good hydrophobicity, and need not clean even running in severe fouling area.
2. It has high mechanical strength. The tensile strength of epoxy glass fiber extracting bar borne interior is 2 times higher than common irons and is 8-10 times of high strength porcelain materials, which enhance the reliability of the running of electric network effectively.
3. Small volume, light weight (1/10-1/7 of porcelain insulator) and unease breakage, which are convenient for transport and installation.
4. It belongs to arcing type structure and needs not survey zero value.
5. Strong weathering and corrosion resistance properties make it can run in various outdoor environments for long time.
6. It can interchange with porcelain insulator of equal load.
