Creepage Extender
CIAC
Creepage Extender is to improve the pollution for post insulators.
Under the vile weather conditions, such as fog, drizzle and filthy
environment, the flashover of the contaminated insulators are the
main reason which cause the power failure. CIAC creepage extender
provides effective protection against the flashover troubles and
eliminates live line flashover of bushings and insulators, enhancing
the high reliability of complete power system.
