《GB/T 18015.2-1999数字通信用对绞或星绞多芯对称电缆 第2部分:水平层布线电缆分规范》由TC213（全国电线电缆标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准与GB/T 18015.1《数字通信用绞或星绞多芯对称电缆 第1部分：总规范》一起使用。这种电缆专用于ISO/IEC DIS 11801：“信息技术 用户楼宇通用布线”中定义的水平层布线。本标准适用于水平层布线的对数少于20个线对或10个四线组的电缆，线对或四线组可具有或没有单独屏蔽。可对这种电缆缆芯包覆统包屏蔽。这种电缆适用于在合适的详细规范中所提到的各种通信系统。本标准所包括的电缆应在通信系统通常使用权的电压和电流下荼。这些电缆不宜连接到例如公共供电那样的低阻抗电源上。电缆安装和运行期间推荐的温度范围由相关详细规范规定。
Scope
This standard is used together with GB/T18015.1 "Pair-twisted or star-twisted multi-core symmetrical cables for digital communications - Part 1: General Specifications". This cable is designed for use in horizontal layer wiring as defined in ISO/IECDIS11801: "General wiring in buildings for information technology users". This standard applies to cables with fewer than 20 pairs or 10 quads wired in horizontal layers, with or without individual shielding. A turnkey shield can be applied to the core of this cable. This cable is suitable for use in various communication systems as mentioned in the appropriate detail specification. Cables covered by this standard shall operate at voltages and currents normally used in communication systems. These cables should not be connected to low impedance sources such as the public supply. The recommended temperature range during cable installation and operation is specified by the relevant detail specification.
