A sub-size sample of Cable-In-Conduit conductor is prepared. Six sub-cables made of 3x4 copper wires are twisted, and they are inserted into a SUS304 pipe (conduit) of the diameter of 17 mm and the length of 0.5 m. A special tool is manufactured to twist or to pull and push the conductor sample. One end of the conduit is fixed, and the opposite end is rotated or pulled with the tool. It is shown that the tensile strain is induced in the wire by twisting the conduit in the same direction to the wire twisting direction and that the strain change of wires is in the order of 1/10 of the conduit.

准备一个亚尺寸的电缆导管导体样品。将由3x 4铜线制成的六个子电缆绞合，并将它们插入直径为17 mm、长度为0.5 m的SUS 304管（导管）中。制造一种特殊的工具来扭转或推拉导体样品。导管的一端是固定的，另一端用工具旋转或拉动。结果表明，导线沿与导线扭转方向相同的方向扭转时，导线中产生拉应变，导线的应变变化量约为导线的1/10。
