| DOW ENDURANCE™ HFDA-0581 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）DOW ENDURANCE™ HFDA-0581 BK在高温下具有稳定的体积电阻率特性。并与一个聚合物系统，证明了与铜导体的兼容性。DOW ENDURANCE™ HFDA-0581 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-0581 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-0581 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-0581 BK的效用。 DOW ENDURANCE™ HFDA-0581 BK is a specially formulated semiconductive, vulcanizable compound designed for use as an extruded conductor shield and bonded insulation shield applications in power cables.(1) DOW ENDURANCE ™ HFDA-0581 BK has stable volume resistivity characteristics at elevated temperatures and is formulated with a polymer system that has demonstrated compatibility with copper and aluminum conductors. DOW ENDURANCE™ HFDA-0581 BK offers outstanding extrusion properties with low melt pressures and low temperature generation that result in outstanding scorch resistance under a wide processing window. (1) DOW ENDURANCE™ HFDA-0581 BK is recommended for use in conjunction with DOW cross-linked polyethylene and tree-retardant cross-linked polyethylene compound. For other polymer insulations as well as EPR and EPDM the user is cautioned to establish the utility of DOW ENDURANCE™ HFDA-0581 BK with each formulation. Applications: DOW ENDURANCE™ HFDA-0581 BK has been designed for semiconductive applications in power distribution and transmission cables for cables rated up to 150 kV. It can be used as inner and outer semiconductive layer for bonded cable applications and as inner semiconductive layer for strippable cable constructions. Contact your Dow representative for further recommendations. Specifications: DOW ENDURANCE™ HFDA-0581 BK is designed for use in power distribution and transmission cables. Power cables with conductor and insulation shielding made of DOW ENDURANCE™ HFDA-0581 BK, prepared using sound, commercial fabrication practice, would be expected to meet the following cable specification(s): IEC: 60502-2 and 60840 HD: 620 S2 and 632 S2 BS: 6622 DIN: VDE 0273 and 0263 Edf: HN-33-S-23 and HN-33-S-52 AEIC: CS8, CS9 ICEA: S-94-649, S-97-682, S-113-684, S-66-524 (NEMA WC7), S-108-720 GB/T 12706, GB/T 11017 |
