<p>PROBLEM TO BE SOLVED: To reduce the space in a tunnel or a manhole which has a bent part with an L-shape, a T-shape, a Y-shape, etc., without taking the allowable bending radius of a cable into consideration. SOLUTION: A 1st power cable 2A is extended into an L-shaped manhole 1 through one cable insertion hole 1a of the manhole 1. A 2nd power cable 2B is extended into the L-shaped manhole 1 through the other cable insertion hole 1b of the manhole 1, which opens in a direction practically perpendicular to the opening direction of the one insertion hole 1a. The 1st power cable 2A and the 2nd power cable 2B are connected to each other via an L-shaped connector 3.</p> |
