陶氏耐久性HFDA-0801 BK超高压电缆是一种特殊配制的半导体、硫化化合物,设计用于高、特高压交联聚乙烯绝缘电缆的导体屏蔽和粘合绝缘屏蔽。(1)陶氏耐久性HFDA-0801 BK超高压电缆已证明与铜、铝导体相容。陶氏耐力HFDA-0801 BK超高压是专门开发利用一种特殊的乙炔碳黑提供一个超光滑的表面,以实现最佳的性能,并在挤压屏蔽和绝缘之间产生一个更完美的界面。因此,可以预期显著提高电缆性能。规范DOW耐久性HFDA-0801 BK超高压设计用于配电电缆。采用良好的商业制造实践制备的Dow耐力HFDA-0801 BK超高压导线和绝缘屏蔽电缆应符合以下规范:AEIC:CS8,CS9 IEC:60502,60840,62067 ICEA:S-108-720;S-94-649;S-97-682,S-93-639 DIN:VDE 0276-632,0276-620 BS:6622 CENELEC:HD620 S1,HD632 S1 ISO 1872-e/ba,khxy,23-g200,c40 nf:c33-223,c33-226 ute:c33-223(1)建议与陶氏交联聚乙烯和阻燃交联聚乙烯化合物一起使用陶氏耐久性HFDA-0801 BK ehv。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-0801 BK超高压的效用。 DOW ENDURANCE™ HFDA-0801 BK EHV is a specially formulated semiconductive, vulcanizable compound designed for conductor shield and bonded insulation shield applications in high and extra-high voltage crosslinked polyethylene insulated cables.(1) DOW ENDURANCE™ HFDA-0801 BK EHV has demonstrated compatibility with copper and aluminum conductors. DOW ENDURANCE™ HFDA-0801 BK EHV was specifically developed utilizing a special acetylene carbon black to provide a supersmooth surface to achieve best in class performance and yielding a more perfect interface between the extruded shield and the insulation. As a result, significantly improved cable performance can be expected. Specifications DOW ENDURANCE™ HFDA-0801 BK EHV is designed for use in power distribution cables. Cables with conductor and insulation shielding of DOW ENDURANCE™ HFDA-0801 BK EHV, prepared using sound commercial fabrication practice, would be expected to meet the following specifications: AEIC: CS8, CS9 IEC: 60502, 60840, 62067 ICEA: S-108-720; S-94-649; S-97-682, S-93-639 DIN: VDE 0276-632, 0276-620 BS: 6622 CENELEC: HD620 S1, HD632 S1 ISO 1872-E/BA, KHXY, 23-G200, C40 NF: C33-223, C33-226 UTE: C33-223 (1) DOW ENDURANCE™ HFDA-0801 BK EHV is recommended for use in conjunction with DOW cross-linked polyethylene and tree-retardant cross-linked polyethylene compounds. For other polymer insulation such as EPR and EPDM's, the user is cautioned to establish the utility of DOW ENDURANCE™ HFDA-0801 BK EHV with each formulation. |
