Zero value insulator refers to the insulator whose potential distribution at both ends of the insulator is close to zero or equal to zero in operation. The effect of zero or low value insulator: the insulation of the line wire depends on the string of insulators, due to manufacturing defects or external effects, the insulation performance of the insulator will continue to deteriorate, when the absolute edge resistance is reduced or zero, it is called low value or zero value insulator
Insulator features:
1, the insulator has high mechanical strength, small dispersion, safe and reliable operation.
2, the insulator low temperature mechanical performance is good.
3, good pollution resistance.
The pollution resistance of the insulator mainly depends on the structure of the product and the shape of the umbrella skirt. We have done a lot of work in this area. The pollution resistance level of the insulator is leading in China, and its equivalent salt density is higher than that of similar products with the same climbing distance and equal diameter umbrella skirt.
4, high earthquake resistance.
5, low radio interference.
