Composite Insulator Creepage Option
- May 10, 2018 -

composite insulators

The selection of creepage distance for composite insulators used in DC systems requires special attention. Neither should the occurrence of frequent tripping due to AC creepage characteristics be selected due to the AC flashover characteristics, nor does it need to blindly excessively increase the creepage distance. The oversight of the umbrella skirt is not conducive to the insulators. Self-cleaning is also likely to cause bridges between umbrella skirts, which may have little effect on improving flash and wet flash voltages, and may even be counter-productive.
