摘要
针对电缆桥架在施工中经常遇到的一些问题,如热镀锌桥架、热浸镀锌桥架是否是同一种桥架,电缆桥架板厚问题,热浸镀锌桥架和热镀锌板桥架镀锌层厚度问题,电缆桥架能不能作为保护导体,沿电缆桥架敷设保护导体问题等,依据相关标准的规定进行分析,为电缆桥架的选择和具体做法提出可供参考的意见和建议。
The common problems in cable supporting system construction,such as whether the hot galvanized and hot dip galvanized cable supporting system are the same kind,the thickness of cable supporting system,the thickness of hot dip galvanized and hot galvanized supporting system,whether the supporting system can be used as protective conductor and the protective conductor laying along the supporting system,are analyzed as per related standards to provide reference and suggestions for the selection and practice of cable supporting system construction.
