《GB/T 18015.4-2007数字通信用对绞或星绞多芯对称电缆 第4部分：垂直布线电缆 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 18015.1一起使用。这种电缆专用于GB/T 18233中定义的工作区布线。包括用于垂直通道或楼层间布线用的无单独屏蔽的20个对绞组或10个四线组及以上的电缆。当垂直安装时，可能要在适用的详细规范中规定附加的长度要求。本标准所包括的电缆应在通信系统通常采用的电压电流下工作。这些电缆不宜被接到如公共供电那样的低阻抗电源上。
Scope
This section is used together with GB/T 18015.1-2007. This cable is dedicated to the vertical wiring defined in GB/T 18233. This standard applies to cables of 20 pairs/10 quads and above without individual shielding for vertical aisle or inter-floor wiring. When installed vertically, additional length requirements may be specified in the applicable detail specification. Cable cores for electricity charges can have total shielding. These cables are suitable for use in various communication systems as mentioned in the applicable detail specification. Cables covered by this standard shall work at voltages and currents normally used in telecommunication systems. These electricity bills should not be connected to a low-impedance source such as the public supply. The recommended temperature range during cable installation and operation is specified in the detail specification.
