DOW ENDURANCE™ HFDA-0693 BK is a specially formulated semiconductive, vulcanizable compound designed for use in conventional extrusion practices as a strippable insulation shield for medium voltage power cable. HFDA-0693 BK was designed to have excellent processability, while having improved resistance to blocking during storage. HFDA-0693 BK is recommended for use over Dow crosslinked polyethylene compounds. This product provides a moderate strip force over a wide temperature range when used in conjunction with these insulation materials. Specifications DOW ENDURANCE™ HFDA-0693 BK is designed for use in power distribution cables. Cables with conductor and insulation shielding of DOW ENDURANCE™ HFDA-0693 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: CS 8 IEC 60502&& |
