DOW ENDURANCE™ HFDA-0580 BK is a specially formulated semiconductive, vulcanizable compound designed for use as an extruded strand conductor shield and bonded insulation shield applications in medium voltage crosslinked polyethylene insulated cables.(1) DOW ENDURANCE™ HFDA-0580 BK has stable volume resistivity characteristics at elevated temperatures and is formulated with a polymer system that assists in obtaining minimum shrink back on aluminum conductors, especially solid conductors. DOW ENDURANCE™ HFDA-0580 BK is not recommended for use with bare copper conductors.

Specifications
DOW ENDURANCE™ HFDA-0580 BK is designed for use in power distribution cables. Cables with conductor and insulation shielding of DOW ENDURANCE™ HFDA-0580 BK, prepared using sound commercial fabrication practice, would be expected to meet the following specifications:

• ANSI/ICEA: S-94-649, S-97-682, S-93-639 / NEMA WC74

• AEIC: CS8

• IEC: 60502

(1) DOW ENDURANCE™ HFDA-0580 BK is recommended for use in conjunction with DOW cross-linked polyethylene and tree-retardant cross-linked polyethylene compounds. For other polymer insulations such as EPR and EPDM's the user is cautioned to establish the utility of DOW ENDURANCE™ HFDA-0580 BK with each formulation.
