ａはプラグイン接続部をそれぞれ示している。By the way, depending on the distance between the electric poles A 1 and A 3 , the bypass line 26 has a considerable length, and it may be necessary to extend and connect some bypass cables prepared in advance. In the present invention, the pair of pull-down cables 25 arranged at both ends of the bypass line 26.
By bypass-connecting the two bypass cables 1 and 1 including a and 25b in the field, the bypass line 26 can be easily formed. Since the bypass cable 1 of the present invention has the male terminal portion 3 at one end and the female terminal portion 4 at the other end, an intervening material such as a straight connecting tube is used between the bypass cables 1 as in the conventional case. Can be directly connected without. The bypass cable 1 is generally wound around a drum in a constant direction, and one of the male end portion and the female end portion, whichever is more fixed, is exposed at the end of winding, so that the bypass cable 1 is used for extension connection. There is no possibility that terminals of the same type will face each other and become unconnectable. In the figure, 22a is a jumper wire, 26
