数字通信用多芯和对绞电缆/扭绞四心电缆.第3部分:工作区电缆.分规范

[中文适用范围]： 本部分规范涉及 IEC 61156-1:2002。这些电缆专门用于 ISO/IEC 11801 中定义的工作区布线。该规范定义了用于工作区布线的单独屏蔽、通用整体芯屏蔽和非屏蔽双绞线或四绞线。这些电缆适用于各种通信系统，相关详细规范中给出了参考。本部分规范涵盖的电缆旨在以通信系统通常采用的电压和电流运行。这些电缆不应连接到低阻抗电源，例如公共电源。安装时建议温度范围为0℃至+50℃。安装时的实际温度范围应在相关详细规范中注明。正常工作温度范围为-40℃至+60℃。 [外文原描述]： IEC 61156-3:2008(E) defines individually screened, common overall core screen and unscreened pairs or quads in cables for work area wiring. These cables are suitable for the various communication systems for which the reference is given in the relevant detail specification. The cables covered by this sectional specification are intended to operate with voltages and currents normally adopted for communication systems. These cables should not be connected to low impedance sources, for example, the public mains electricity supply. The cables are specifically intended for work area wiring as defined in ISO/IEC 11801. This third edition cancels and replaces the second edition published in 2003. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition: a) new requirements for new cables Cat3, and Cat5 applications; b) a better numbering in order to take into account the generic specification.
