Aiming at the current status that the quality of massive used cable conduit is not high,which affects the quality of the cable laying,and further influences the service life of the cable and the reliability of using electricity,we developed the cable duct detecting instruments using the existing mature technology combined with the requirements of cable laying regulations.

As the example of the solution for the water leakage of the cable trench and cable well in Jinfeng District Power Supply Bureau,describes the methods to prevent the cable pipe and wall from water leakage.
