Communication cables, home decoration wires

Indoor (outdoor) telephone communication cables are suitable for wiring in telecommunication engineering, serving as links between floor wiring systems in communication systems. They can also be used for connections between communication outlets (information sockets) and telecommunication equipment (such as telephones, faxes, etc.). In areas with severe interference, shielded cables should be used.

Multi-pair local communication cables are produced in accordance with the standard twisted pitch of digital cables, which reduces the mutual crosstalk interference between pairs, thereby reducing the crosstalk attenuation of the cables and minimizing power loss. It is used for audio connection between the main distribution frame within the program-controlled switching office and the users of the switching office, and can support low-rate data transmission. Connections include digital telephones, faxes, program-controlled switches and other digital communication devices. 4 pairs are used for the connection of branch lines in telecommunication engineering cabling, and 10 pairs, 20 pairs, 30 pairs, 50 pairs, 100 pairs, etc. are used for the connection of main lines.

1、电缆应避免遭受机械性外力、过热、腐蚀、辐射、磨损等危害。电缆的敷设需要外部良好的环境支持，如果很容易遭受不良因素的干扰，容易加大对其的损害破坏，容易引发线路故障和事故。

2、在同一工程中或电缆通道中，均应按强电至弱电的上下排列顺序原则来配置，将通信电缆的放置于最下面。

3、导体的长期允许工作温度为-40℃~+50℃，月平均最 大相对湿度为95%（+25℃）。

4、电缆允许敷设与安装的温度不低于-10℃。

5、电缆的最小弯曲半径为电缆外径的15倍。
