Visico™ LE0542是一种硅烷交联黑色聚乙烯化合物,专门设计用于半导体导体屏蔽和能量电缆的粘合绝缘屏蔽。用于与低密度聚乙烯-硅烷交联绝缘材料共挤出。应用Visico™ LE0542设计用于额定电压高达36kV的硅烷交联中压电缆中的半导体屏蔽。可作为粘结电缆结构的内外屏,也可作为可剥离电缆结构的内屏。当使用声音挤压实践和测试程序进行加工时,规范Visico™ LE0542满足以下适用要求:IEC 60502-2 CENELEC HD620 S2特殊功能Visico™ LE0542是一种现成的半导体化合物,不需要再添加催化剂母粒。Visico™ LE0542通过与硅烷绝缘层共挤出的催化剂的迁移交联。炭黑和添加剂在Visico™ LE0542中的良好分布将导致半导体屏的光滑。 Visico LE0542 is a silane crosslinkable black polyethylene compound, specially designed for semiconductive conductor screen and bonded insulation screen of energy cables. It is used for co-extrusion with LDPE silane crosslinkable insulation materials. Applications Visico LE0542 is designed for semiconductive screens in silane crosslinkable medium voltage cables with rated voltages up to 36 kV. It can be used as inner and outer screen for bonded cable constructions and as inner screen for strippable cable constructions. Specifications Visico LE0542 meets the applicable requirements as below when processed using sound extrusion practice and testing procedure: IEC 60502-2 Cenelec HD620 S2 Special features Visico LE0542 is a ready-to-use semiconductive compound, which requires no further addition of a catalyst masterbatch. Visico LE0542 crosslinks via the migration of catalyst from its co-extrusion with silane insulation layer. The excellent distribution of carbon black and additives in Visico LE0542 would result in a smooth semiconductive screen. |
