本文件规定了以下类型额定电压U0/U:300/500 V的多芯和多对电缆的要求、结构和尺寸: -裸露或受保护接线（0.5 mm2到2.5 mm2，芯数从2到48）的无屏蔽、有护套屏蔽、护套，用于裸露或保护接线（0.5 mm2至2.5 mm2，芯数从2至8）；-裸露或受保护接线（0.5 mm2至1.5 mm2，屏蔽线对数为2至7）的无屏蔽、有护套裸露或受保护布线用屏蔽、护套（0.5 mm2至1.5 mm2，未屏蔽线芯对数为2至7）。 所有电缆均采用绞合镀锡铜导线，无卤素，壁厚薄，绝缘良好 标准壁厚护套。电缆类型规定用于暴露环境（E级），以及 对于受保护的情况（P类）。它们在铁路车辆中用作固定配线或配线 在操作中遇到有限的弯曲。 交叉引用:EN 45545-1EN 60332-1-EN 45545-1EN 60332-1-2EN 60332-3-3-24EN 61034-2EN 60811（所有零件）EN 50306-3:2020EN 50306-3:2020EN 50264-1:2008EN 50306-1:2020EN 50306-1:2020EN 50306-1:2020EN 50305:2020EN 50343EN 60332-1-1-1-1-1-2-2-1-2-2-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-。

This document specifies requirements for, and constructions and dimensions of, multicore and multipair cables rated voltageU0/U: 300/500 V, of the following types: — unscreened, sheathed for either exposed or protected wiring (0,5 mm2to 2,5 mm2, number of cores from 2 to 48);— screened, sheathed for either exposed or protected wiring (0,5 mm2to 2,5 mm2, number of cores from 2 to 8);— unscreened, sheathed for either exposed or protected wiring (0,5 mm2to 1,5 mm2, number of screened pairs of cores from 2 to 7).— screened, sheathed for either exposed or protected wiring (0,5 mm2to 1,5 mm2, number of unscreened pairs of cores from 2 to 7). All cables have stranded tinned copper conductors, halogen-free, thin wall thickness insulation and standard wall thickness sheath. Cable types are specified for use in exposed situations (Class E), and for protected situations (Class P). They are for use in railway rolling stock as fixed wiring or wiring where limited flexing in operation is encountered.Cross References:EN 45545-1EN 60332-1-2EN 60332-3-24EN 61034-2EN 60811 (all parts)EN 50306-3:2020EN 50264-1:2008EN 50306-1:2020EN 50306-2:2020EN 50305:2020EN 50343EN 60332-3-25EN 60754-1EN 60684-2EN 50355EN 60754-2EN 45545-2Replaces BS EN 50306-4:2002 which remains currentAll current amendments available at time of purchase are included with the purchase of this document.
