<p>PROBLEM TO BE SOLVED: To provide a method, which does not require a hand hole and assures easier and effective work, as a method of branching an underground low voltage cable for a pole made of a steel pipe. SOLUTION: In the construction field of the steel pipe pole 13 including an aperture 14 for guiding an intra-pole cable at the lower portion of the pole located above the ground level, a branching connection end portion of each underground low voltage cable 16 is raised up to the circumference of the lower portion of the steel pole 13 above the ground, using a pair of bending pipe 12 to be disposed to extend upto the adjacent external circumferential portion just above the ground 25 of the steel pole 13 from the aperture end portion of a pair of underground conduits 11. The branching connection portion of the corresponding underground low voltage cable 16 and the intra-pole cable 17 are connected with a branching-connection method using a compression pipe terminal 18. Thereafter, the lower circumferential portion above the ground of the steel pole 13 as a whole including the intra-pole cables 16, 17 and the upper end portions of the bending pipes 12 is covered with a cover 15.</p> |
