しない剥離しやすい材料としている。In the cable 1 of the present invention, a plurality of steel wires 2 are brought together and bound by a band 3. This steel wire 2
Are set in accordance with the place of use and the load. The steel wire 2 is a PC steel stranded wire 6 formed by twisting a plurality of side wires 5 around a core wire 4. A coating inner layer 7 made of a synthetic resin is formed around the core wire 4 and the side wire 5. Formed on the outer periphery of the inner layer 8 and the outer coating layer 9, and the lubricating material 10 is interposed between the inner coating layer 8 and the outer coating layer 9, so that the intermediate coating layer 8 does not weld to the inner coating layer 7. The material is easy to peel.
