标准摘要
[中文适用范围]： 本部分IEC 61156规定了多芯、对称对和四芯电缆的定义、要求和测试方法。 本文件适用于通信系统，如局域网(LANs)和数据通信电缆。它还适用于工业应用、客户场所布线和通用布线中使用的电缆，包括安装电缆和工作区布线电缆，这些电缆在ISO/IEC 11801(所有部分)中定义。 本文件涵盖的电缆旨在用于通信系统中通常遇到的电压和电流。虽然这些电缆不打算与低阻抗源一起使用，例如公共电源主电源，但它们旨在用于支持低电压远程供电应用，包括但不限于ISO/IEC/IEEE 8802-3中规定的以太网供电。根据安装实践支持这些应用的能力的更多信息在IEC 61156-1-4、IEC TR 61156-1-6和ISO/IEC TS 29125中给出。 [外文原描述]： IEC 61156-1:2023 specifies the definitions, requirements and test methods of multicore, symmetrical pair and quad cables. This document is applicable to communication systems such as local area networks (LANs) and data communication cables. It is also applicable to cables used for industrial applications, customer premises wiring and generic cabling comprising installation cables and cables for work area wiring which are defined in ISO/IEC 11801 (all parts). The cables covered by this document are intended to operate with voltages and currents normally encountered in communication systems. While these cables are not intended to be used in conjunction with low impedance sources, for example the electric power supplies of public utility mains, they are intended to be used to support the delivery of low voltage remote powering applications including but not restricted to Power over Ethernet as specified in ISO/IEC/IEEE 8802-3.
