DOW ENDURANCE™ HFDK-9253 S is a long-life, unfilled, crosslinkable, low density, super clean polyethylene insulation compound developed especially for the insulation of high voltage power cables. DOW ENDURANCE HFDK-9253 S 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 S 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 S is recommended for the insulation of high voltage power transmission cables rated up to 230 kV
