| DOW ENDURANCE™ HFDK-4201 SC 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-4201 SC 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-4201 SC is recommended for the insulation of high voltage power transmission cables rated up to 230 kV Specifications HFDK-4201 SC is designed for use in power distribution and transmission cables. Cables insulated with HFDK-4201 SC, using sound commercial manufacturing practice, would be expected to meet the latest editions of the following specifications and regulations: IEC 62067, 60840 CENELEC HD632 S2 AEIC CS9 ANSI/ICEA: S-108-720 GB/T 11017, GB/Z 18890&& |
