2.Materials advantage: 

1). Each 25kv railway polymer insulator is tested before shipment.

2). The insulator with fine internal and external insulating ability.

3). It is not so easy to be damaged in the course of transporting and installing.

4). High tracking resistance silicone rubber used for sheathing.

5). Unique self-cleaning property, reduced maintenance cost.



Regularly clean the insulator

 

During the long-term operation of the transmission line, a layer of impurities is attached to the surface of the transmission line, which causes certain damage to the insulation performance of the insulator. Therefore, in order to ensure the insulation performance of the insulator, the cleaning work can be performed to insulate the insulator surface. The impurities are removed. Moreover, while cleaning, the insulator should be carefully inspected to see if there are any defects such as cracks and damage on the surface. When problems are found, they should be replaced in time.
