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.

准备了电缆导管导体的小尺寸样品。将由3x4铜线制成的六根子电缆绞合，并将其插入直径为17mm、长度为0.5m的SUS304管(导管)中。制造了一种特殊的工具来扭转或拉动和推动导体样品。导管的一端固定，另一端用工具旋转或拉动。结果表明，通过沿与线材扭转方向相同的方向扭转导管，在线材中引起拉伸应变，并且线材的应变变化约为导管的1/10。
