Discharge Resistant Insulation
Partial discharge is caused by the electrical breakdown of air in the voids within the cable insulation – and it can lead to cable failure.
Only Kerite manufactures a corona resistant insulation system that meets ICEA standard S-94-649-2013.
The test that evaluates discharge resistance of different insulation types (ASTM D2275) shows Kerite HVK Discharge Resistant EPR™ insulation with no insulation erosion after over 250 hours of testing.
Discharge resistance prevents the treeing process in Kerite Discharge Resistant EPR™ insulation and as a result, Kerite cable can last the lifetime of the installation.
