陶氏耐久HFDA-0580 BK是一种特殊配方的半导体、硫化化合物,设计用于中压交联聚乙烯绝缘电缆的挤压股导线屏蔽和粘合绝缘屏蔽。(1)陶氏耐久HFDA-0580 BK在高温下具有稳定的体积电阻率特性。与一个聚合物系统,以帮助获得最小收缩对铝导体,特别是固体导体。不建议与裸铜导线一起使用DOW耐久性HFDA-0580 BK。规格DOW耐久性HFDA-0580 BK设计用于配电电缆。采用良好的商业制造实践制备的具有Dow耐久性HFDA-0580 BK导体和绝缘屏蔽层的电缆应符合以下规范:ANSI/ICEA:S-94-649、S-97-682、S-93-639/NEMA WC74 AEIC:CS8 IEC:60502(1)Dow耐久性HFDA-0580 BK建议与Dow交叉链路一起使用。ED聚乙烯和树阻燃交联聚乙烯化合物。对于其他聚合物绝缘,如EPR和EPDM,用户应注意在每种配方中建立陶氏耐久性HFDA-0580 BK的效用。 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. |
