DOW ENDURANCE™ HFDB-4202 EC is a long-life, water-tree-retardant, unfilled, crosslinkable, low density polyethylene insulation compound. The permanent tree-retardant additive provides improved performance in power cables in service involving exposure to moisture while retaining the excellent physical, electrical, and processing attributes of conventional, crosslinkable polyethylene.
DOW ENDURANCE™ HFDB-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
Proven in the field for over 25 years, at a broad cross section of geographical conditions, 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™ HFDB-4202 EC compound represents the state-of-the-art in tree-retardant, power cable insulation compounds.
Specifications
DOW ENDURANCE™ HFDB-4202 EC tree-retardant compound is designed for use in power distribution and sub-transmission cables, especially in underground applications. DOW ENDURANCE™ HFDB-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™ HFDB-4202 EC, using sound commercial fabrication manufacturing practice, would be expected to meet the latest editions of the following specifications and regulations:
