DOW ENDURANCE™ HFDA-0802 BK EC is a specially formulated semiconductive, vulcanizable compound designed for conductor shield and bonded insulation shield applications in medium and high voltage crosslinked polyethylene insulated cables.(1) DOW ENDURANCE™ HFDA-0802 BK EC has stable volume resistivity characteristics at elevated temperatures and is formulated with a polymer system that assists in obtaining minimum shrinkback on aluminum conductors, especially solid conductors. DOW ENDURANCE™ HFDA-0802 BK EC is not recommended for use with bare copper conductors.

DOW ENDURANCE™ HFDA-0802 BK EC was specifically developed utilizing a special acetylene carbon black to provide a supersmooth surface to achieve best in class performance and yielding a more perfect interface between the extruded shield and the insulation. As a result, significantly improved cable performance can be expected.

Specifications
DOW ENDURANCE™ HFDA-0802 BK EC is designed for use in power distribution cables. Cables with conductor and insulation shielding of DOW ENDURANCE™ HFDA-0802 BK EC, 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-0802 BK EC is recommended for use in conjunction with DOW cross-linked polyethylene and tree-retardant cross-linked polyethylene compounds. For other polymer insulation such as EPR and EPDMs, the user is cautioned to establish the utility of DOW ENDURANCE™ HFDA-0802 BK EC with each formulation.
