HFDK-0586 BK是一种基于乙烯共聚物的可交联半导体化合物,设计用于中高压电缆的导体屏蔽和粘合绝缘屏蔽。HFDK-0586 BK与铜和铝具有极好的兼容性。它具有优良的导电性,优良的机械性能,也经过老化处理。光滑度和挤出性(同样在三倍挤出机中)非常好。规范:采用良好的商业制造实践制备的导体或绝缘屏蔽层为HFDK-0586 BK的电缆应符合以下行业电缆规范的最新版本:AIEC:CS 8-00和CS 7-93 BS:6622 DIN:VDE 0263和0276 IEC:60502和60840 ICEA:S 95 658和S 66 524(NEMA WC7-1966)NF:C 33-223 HD:620 S1 DOW ENDURANCE™ HFDB-0586 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 ™ HFDB-0586 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™ HFDB-0586 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™ HFDB-0586 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™ HFDB-0586 BK with each formulation. Applications DOW ENDURANCE™ HFDB-0586 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™ HFDB-0586 BK is designed for use in power distribution and transmission cables. Power cables with conductor and insulation shielding made of DOW ENDURANCE™ HFDB-0586 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 AEIC: ICEA: S-94-649, S-97-682, S-113-684, S-66-524 (NEMA WC7), S-108-720 GB/T 12706, GB/T 11017 |
