Dow ENDURANCE™ HFDK-4202 EC

About
DOW ENDURANCE™ HFDK-4202 EC Polyethylene Compound is a long life water tree retardant, unfilled, crosslinkable low-density polyethylene compound. The permanent tree retardant additive provides improved performance service involving exposure to moisture while retaining the excellent physical, electrical and processing attributes of crosslinkable polyethylene. DOW ENDURANCE HFDK-4202 EC compound provides electric utilities with: State-of-the-art “water” tree-retardant technology, consistently outperforming conventional XLPE in all accelerated cable wet aging tests at ambient and elevated temperatures Technology which has been proven in the field for over 25 years, demonstrating excellent reliability and help achieving lowest life cycle costs Excellent electrical performance demonstrated by very high aged electrical strength and very low aged dissipation factor and power loss. DOW ENDURANCE HFDK-4202 EC Compound represents the state-of-the-art in tree-retardant, power cable insulation compounds. Specifications DOW ENDURANCE HFDK-4202 EC tree-retardant compound is designed for use in power distribution and sub-transmission cables, especially in underground applications. DOW ENDURANCE HFDK-4202 EC provides improved performance over XLPE cables and is recommended, with or without moisture barriers, for use as cable insulation up to and including 69 kV applications. Cables insulated with DOW ENDURANCE HFDK-4202 EC, using sound commercial manufacturing practice, would be expected to meet the following specifications and regulations: ANSI/ICEA: S-94-649, S-97-682, S-93-639 / NEMA WC74 (TR-XLPE requirements) AEIC: CS8 RUS 50-70 (U-1) CEA: WCWG-01, WCWG-02 UL 1072 IEC: 60502, 60840 CENELEC: HD 620 S1, Part 1, DIX 3 to 14 DIN VDE 0276-620 BSI BS 6622 GB/T 12706 DL/T 1070&&
