牌号简介	陶氏耐久HFDB-4201 VC是一种长寿命、未填充、交联、低密度聚乙烯绝缘化合物，专为配电和输电电缆绝缘应用而设计。它的污染程度非常低，并带有“非常干净”（vc）的名称。陶氏耐久性HFDB-4201 VC被设计成具有低水平的添加剂布卢姆，具有较长的储存寿命、低粉尘和增强程度的防灼烧性能，适用于电缆制造过程中较长的生产运行长度。对于额定电压小于150千伏、应力小于7千伏/毫米的配电和输电电缆的绝缘，建议采用陶氏耐久性HFDB-4201 VC。规范DOW耐久性HFDB-4201 VC设计用于配电和传输电缆。根据良好的商业生产实践，采用DOW耐久性HFDB-4201VC绝缘的电缆应符合以下规范和法规的最新版本：IEC 60502、60840 GB/T 12706 ANSI/ICEA：S-94-649、S-97-682、S-93-639/NEMA WC74 CENELEC HD 620 S2 BSI BS 6622、7870-4适用于美国制造的产品尼利。 DOW ENDURANCE™ HFDB-4201 VC is a long-life, unfilled, crosslinkable, low density polyethylene insulation compound designed for distribution and transmission power cable insulation applications. It has a very low level of contamination and bears the designation Very Clean (VC). DOW ENDURANCE™ HFDB-4201 VC has been designed to have a low level of additive bloom for a long storage life, low dusting and an enhanced degree of scorch retardance for long production run lengths during cable manufacture. DOW ENDURANCE™ HFDB-4201 VC is recommended for the insulation of power distribution and transmission cables rated at less than 150 kV with stresses less than 7 kV/mm. Specifications DOW ENDURANCE™ HFDB-4201 VC is designed for use in power distribution and transmission cables. Cables insulated with DOW ENDURANCE™ HFDB-4201VC, using sound commercial manufacturing practice, would be expected to meet the latest editions of the following specifications and regulations: IEC 60502, 60840 GB/T 12706 ANSI/ICEA: S-94-649, S-97-682, S-93-639/NEMA WC74 CENELEC HD 620 S2 BSI BS 6622, 7870-4 Applicable to USA manufactured product only.	DOW ENDURANCE™ HFDK-9253是一种低密度、低垂度、交联聚乙烯，设计用于中高压电力电缆绝缘的应用，符合IEC 60502的要求。它具有以下重要优势。1.优异的热稳定性2.良好的挤压性能3.良好的热定型性能4.污染水平极低 Overview HFDK-9253 is a long-life, unfilled, crosslinkable, low sag, low density polyethylene insulation compound designed for distribution and transmission power cable insulation applications. HFDK-9253 has been designed for cable production processes on horizontal vulcanization lines and for cables with thick insulation manufactured on standard catenary vulcanization lines. HFDK-9253 has a low level of additive bloom for a long storage life, low dusting and an enhanced degree of scorch retardance for long production run lengths during cable manufacture. HFDK-9253 is recommended for the insulation of power distribution and transmission cables rated up to 69 kV Specifications HFDK-9253 is designed for use in power distribution and sub-transmission cables. Cables insulated with HFDK-9253, using sound commercial manufacturing practice, would be expected to meet the latest editions of the following specifications and regulations: ANSI/ICEA: S-94-649, S-97-682, S-93-639/NEMA WC74 AEIC CS8 UL 1072 CENELEC HD 620 S2 IEC 60502, 60840 GB/T 12706 BSI BS 6622, 7870-4
