Composite polymer insulator is of high strength and light weight. A synthetic insulator is 1/5 of that of porcelain insulator, but the circum-tensile strength of insulator is very high. Generally, it can be above 6000mpa. Its umbrella skirt is an organic polymer structure of silicone rubber.Therefore, it has a strong anti-pollution performance.
The product has reliable structure and will not damage the core rod. It belongs to the rod-shaped insulation structure.
1.No flaw,crack in the surface and interior
2.Can withstand the sawing, milling, planning, drilling, lathe and other mechanical processing.
3.Internal thread can be tapping with screw tap, external thread can be polished, but not allowed to bear overload.
4.It has good damping, creep resistance, fatigue resistance, fracture resistance, high temperature resistance, stress corrosion resistance etc.
