Silicone rubber composite insulator as the porcelain insulator's replacement product, can improve sewage Lightning pressure, reduce the line operation and maintenance workload and blackout time to a bare minimum, improve power supply reliability, and its main features as following:

1. Tolerance performance to be outstanding.
2. Without cleaning maintenance.
3. Need no to check zero value.
4. The weight is light. It is just 1/7-1/10 of the porcelain insulation substring, it is very convenient to transport and install.
5. The elasticity is good, not brittle. The silicon rubber material still has the good elasticity, even in - 60degree, therefore, this product nearly doesn't exist the problem of breakage durning transporting and installing.
