Suspension Clamp Refers To An Insulator Whose Potential Distribution Across The Insulator Is Close To Zero Or Equal To Zero During Operation.

In order to prevent dust and other dirt from adhering to the surface of the insulator, the Suspension Clamp is formed by the voltage across the insulator, that is, creepage. Therefore, increasing the surface distance of the Suspension Clamp, that is, the creepage distance, the distance along the surface of the Suspension Clamp is the leakage distance. Crawl distance. Crawl distance = surface distance / system maximum voltage. Depending on the degree of contamination, heavy dirt areas generally use a creepage distance of 31 mm / kV.


Suspension Clamp refers to an insulator whose potential distribution across the insulator is close to zero or equal to zero during operation. Effect of zero or low value insulators: The insulation of the line conductors depends on the insulator string. The insulation performance of the Suspension Clamp is degraded due to manufacturing defects or external influences. When the insulation resistance is reduced or zero, it is called low value or Suspension Clamp. We have tested the line, and the ratio of zero or low value insulators is as high as 9%.

The indoor joint binding Suspension Clamp; for the outer plastic post insulator, the letter L before the dash indicates multi-edge, the letters A, B, D indicate that the mechanical damage load is 3.75, 7.5, 20kN, respectively. After the letter, the numerator indicates the rated voltage of kilovolts, and the denominator is the mechanical damage load kN number.
