Summary of power cable knowledge in building electrical engineering
The laying mode of cable engineering shall be determined according to engineering conditions, environmental characteristics, cable type, quantity and other factors, and shall be selected according to the requirements of reliable operation, easy maintenance and the principle of reasonable economy and technology. Generally, the power cable laying methods are pipe laying, trench laying, tunnel laying, direct burial laying, underwater laying, and the combination of the above methods. The specific laying methods are divided into manual laying and mechanical laying. The cable laying mode shall be selected according to the cable type and number, cable path characteristics and other factors in the project.
