摘要
输变电工程电缆沟道形式多种,选择适合具体工程的电缆沟非常重要。因工程启用后电缆沟道内将布满各种电缆,如果在生产运行中沟道出现问题,几乎无法彻底修复,只能局部维持性的修理,为生产运行留下长期隐患。
There are a variety cable channel forms of power transmission and transformation project, choosing suitable cab-le trench for concrete engineering is very important. Because project enabled with al kinds of cable trench, if there are ch-annel problems in the production operation, almost can not be completely repaired, only can get local maintenance repair, le-aving long-term problems for production and operation.
