Advantages of Polymer Insulator
- Polymer insualtor has Superior electrical performance, and high mechanical strength.
The FRP rod of polymer insulator, has good tensile and bending strength,which is 2 times higher than that of ordinary steel, and 8-10 times higher than that of high-strength porcelain materials.Thus will effectively improve the reliability of safe operation.
- Polymer Insulator has good anti-pollution performance: strong anti-pollution flashover voltage.
Its wet withstand voltage and pollution withstand voltage are 2~2.5 times of the same creepage distance of porcelain insulator. There is no need to clean, and it can operate safely in heavily polluted areas.
3.Polymer Insulator has small size, light weight (only 1/6~1/9 of the same voltage levelof porcelain insulator), light structure, easy to transport and easy to install.
4.The silicone rubber umbrella of polymer insulator has good water-repellent properties.
Its overall structure will keep the internal insulation from moisture.It does not require preventive insulation monitor tests. It also does not require cleaning. So that reduces the workload of daily maintenance.
- Polymer Insulator has good sealing performance, strong electrical corrosion resistance.
The sillion rubber shed has a level of TMA4.5 resistance to trace tracking. The shed has good aging resistance, corrosion resistance, and low temperature resistance. Making it able to be used in -40℃~-50℃ areas .
- Polymer Insulator has strong impact resistance and shock resistance, good brittle resistance and creep resistance. It is not easy to break. It also has high bending strength, high torsion strength. So that it can withstand internal pressure.And it can be combined with porcelain and glass insulators Interchangeability.
