<p>PURPOSE:To enable a problem of corona generation to be solved by providing a collar in two-division cylindrical shape for holding a conductor at least one conductor holding part of a plurality of conductor holding parts, an armor rod which is wound on the conductor at both sides from both edge parts of this collar, and a clamp which holds a central part of the above collar. CONSTITUTION:Two semi-cylindrical members 19 are combined for holding a conductor 11b and its recessed part ring spring 28 is fitted, thus constituting a collar 16 for holding the conductor 11b. Then, an armor rod 17 is wound onto the conductor 11b at both sides from an outer periphery at both edges of the collar 16 so that the tip hits against a flange 24 of the collar 16, thus regulating the move in an axis line of the collar 16. Also, the move in peripheral direction of the collar 16 is regulated by clamping force of the armor rod 17 and the ring spring 28. Then, the clamp 18 is fitted at a clamp-fitting part of the collar 16. An inner diameter of the clamp 18 is made slightly larger than an outer diameter of a clamp-fitting part 22 and the collar 16 can rotate within the clamp 18, thus enabling the conductor 11b to be rotated.</p> |
