Resistance to zhang insulator
1, electrical superior performance, high mechanical strength, internal bearing epoxy glass fiber lead out than the average steel bar bending strength 2 times, is high strength of ceramic materials of 8 ~ 10 times, effectively improve the safe operation of the reliability.

2, be able to bear or endure corrupt performance is good, strong ability to fight pollution flashover, the wet tolerance voltage and filthy tolerance for the same voltage climb from the porcelain insulator were 2 ~ 2.5, and does not need to clean, can in heavy impurity regional security operation.

3, small volume, light weight (for only with voltage grade of porcelain insulator were 1/6 ~ 1/9), with light structure, easy to transport and install.

4, silicone rubber umbrella skirt with good water resistance of hate, its whole structure guarantee the inner insulation not damp, do not need to undergo preventive insulation monitoring test, do not need to clean, reduce the daily maintenance work.

The sealing performance, good electrical erosion ability, umbrella skirt material leakage resistance of the mark TMA4.5 level, has the good aging resistance, corrosion resistance, low temperature performance, can be applied to 40 ℃ ~ + 50 ℃ area.
