| DOW ENDURANCE™ HFDA-0693 BK LS is specially formulated semiconductive, vulcanizable compound designed for use in conventional extrusion practices as a strippable insulation shield for medium voltage power cable. DOW ENDURANCE™ HFDA-0693 BK LS was designed to have excellent extrusion processing. DOW ENDURANCE™ HFDA-0693 BK LS is an easy stripping insulation shield recommended for use over DOW ENDURANCE™ crosslinked polyethylene compounds. This product provides low strip force over a wide temperature range when used in conjunction with Dow insulation materials. Specifications: DOW ENDURANCE™ HFDA-0693 BK LS is designed for use in power distribution cables. Cables with conductor and insulation shielding of DOW ENDURANCE™ HFDA-0693 BK LS, 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&& |
