随着城镇建设的不断发展,城镇规划档次的不断提高,许多地方都要求城区的明线网路改为地下铺设。对有线电视的明线网路进行地埋,除了可以美化环境改善城市风貌提高城市品位外,还能减少雷电对有线电视网的危害,提高系统的多项指标,减少网路的故障率,延长电缆的使用寿命。因此,尽管有线电视网地埋建设的成本较高,原先基本上都是明线架设的有线电视网还是越来越多地要求进行地埋暗设的施工。
With the continuous development of urban construction and the continuous improvement of the urban planning level, many places require that the open line network in the urban area should be changed to be laid underground. In addition to beautifying the environment to improve the urban style and improve the urban quality, it also can reduce the harm of thunder and lightning to the cable television network, improve various indicators of the system, reduce the failure rate of the network, and extend the cable The service life. Therefore, despite the high cost of land-based cable television networks, cable television networks, which used to be basically cable-based, are still increasingly required to be buried in the ground.
