PROBLEM TO BE SOLVED: To provide a joint type branched cable capable of monitoring deterioration in each section between junction sections at the time of regular inspection or the like, or always monitoring shielding layer current or voltage for each section between the junction sections, capable of early confirmation of an accident point in case of abnormality, and diagnosing deterioration of a single body of the joint section, that is, checking electrical performance. SOLUTION: An end section of a semiconductive rubber layer 50 positioned inside an insulation tube 35 is overlapped by a prescribed length (ΔL) from an end of hardware 36 is extended in the lengthwise direction of the cable. A prescribed radial clearance (ΔR) is maintained between the hardware 36 and the end of the semiconductive rubber layer 50. A connector box A of cable shielding layer 3 is formed in the insulation tube 35. |
