标准摘要
[中文适用范围]: 本部分 IEC 61156 是 sectional specification(分部分规范),与 IEC 61156-1:2002 相关。这些电缆专门用于垂直布线(riser wiring),最高至 ISO/IEC 11801:1995 中定义和规定的 5 类(D 类)。本规范定义了 individually screened(单独屏蔽)或 unscreened(非屏蔽)的 pairs/quads(双绞线/四绞线)电缆,带或不带整体公共屏蔽层。当垂直安装时,可能需要额外的长度要求,这些要求在相关规范中定义。这些电缆适用于相关详细规范中给出的各种通信系统。本分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源,例如公共 mains electricity supply(市电)。安装期间的推荐温度范围为 0°C 至 +50°C。正常操作温度范围为 -40°C 至 +60°C。实际温度范围应在相关详细规范中指明。 [外文原描述]: IEC 61156-4:2009(E) is a sectional specification and relates to IEC 61156-1:2002. The cables are specifically intended for riser wiring up to category 5 (class D) as defined and specified in ISO/IEC 11801:1995. It defines individually screened or unscreened pairs/quads cables, with or without overall common screen. When installed vertically extra length requirements may be applicable and are defined in the relevant specifications. This edition constitutes a technical revision. The main changes can be found in subclauses 3.3.1.2, 3.3.2, 3.3.4, 3.3.5, 3.3.5.1, 3.3.5.2, 3.3.6 and 3.4. This publication is to be read in conjunction with IEC 61156-1:2002 .
