摘要
近年来城镇道路改造力度不断加大,部分地方的有线电视架空网络在同步改造时遇到了一些麻烦,既无法进行地埋,架空时线路又不让设置转角拉线和终端拉线,等径杆的应用比较有效地解决了以上问题。
Recent years, town road transformation is strengthened. CATV aerial network at some places has encountered some problems. Underground laying, aerial corner wiring and terminal wiring are all forbidden. The application of diameter pole can solve the problems.
