DOW ENDURANCE™ HFDK-9253 EHV is a long-life, unfilled, crosslinkable, low density polyethylene insulation compound of extreme cleanliness developed especially for the insulation of power cables that employ high electrical stresses. DOW ENDURANCE HFDK-9253 EHV has been designed for cable production processes on horizontal vulcanization lines and for cables with thick insulation manufactured on standard catenary vulcanization lines. DOW ENDURANCE HFDK-9253 EHV has been designed with a non-migrating stabilizer providing high thermal stability, long term stability and optimum crosslinking behavior. It has an enhanced degree of scorch retardance for fine mesh filtering and long production run lengths during cable manufacture.

DOW ENDURANCE HFDK-9253 EHV is recommended especially for the insulation of extra high voltage power transmission cables rated above 230 kV.
