POWER CABLE LAYING METHOD USING V-SHAPE PIPE LINE

摘要

PROBLEM TO BE SOLVED: To provide a power cable laying method using a V-shape pipe line capable of preventing a pipe line from being stretched outside by its own thermal expansion and freely deciding a laying shape at the outside of a pipe line. SOLUTION: A cross sectional structure of a pipe line is set V-shaped so as to strengthen friction between a power cable and a pipe line by receiving a power cable with two planes formed in V shape. As another method, the cross sectional structure of the pipe line is set roughly V-shaped and formed an arch-shaped cross sectional grove at the root of the V shape planes, whereby the method for receiving the power cable with the arch-shaped grove of the pipe line can be provided.
