HVCE creepage extenders represent a long-term solution to pollution flashovers, by
making a permanent addition to the creepage distance. This increases flashover voltage
and reduces leakage currents and surface electrical stress. Creepage extenders also
improve the insulator shape and increase the strike distance.
Heat-shrinkable HVCE creepage extenders are flexible polymeric skirts, coated internally
with a trackresistant mastic for bonding to the porcelain. These are available to
fit insulators and bushings up to 500 kV, with shed diameter 80 mm to over 390 mm.
Wrap-around HVCE-WA creepage extenders are custom-made from a semi-rigid polymer,
and are bonded in place with a pressure sensitive track-resistant mastic. HVCE-WA
reepage extenders are cold-applied. There is no need to disconnect to install wrap-around
creepage extenders. These are available to fit insulators and bushings up to 500
kV, with shed diameter 100 mm to over 1000 mm.
