REMOVING METHOD OF THREE-PHASE POWER CABLE

摘要

PROBLEM TO BE SOLVED: To effectively use an existing conduit by facilitating removing work of a three-phase power cable.

SOLUTION: A gap is formed between core cables 26 when an intervening member 28 of a three-phase OF cable 12 is drawn out, reducing a drawing resistance of the core cable 26. So, a single core cable 26 is easily drawn out. The drawing resistance of remaining core cables 26 is further reduced when one of the core cables 26 is drawn, so remaining two core cables 26 are easily drawn out. A shield layer 34 and an anti-corrosion layer 30 are reduced in diameter when a depletion is assured inside the shield layer 34 and the anti-corrosion layer 30 in the processes, allowing easy drawing in the state of decreased diameter.
