It is a partial view for explaining the relationship between the inner wall and the power cable lead-in wire, in which 1 is a refrigerant transport conduit made of a flexible material, 2
3 is a cleat fixed to the receiving frame, and 3 is a power cable lead-in wire. In such a structure, when the power cable is drawn into the bend of the conduit 1, the length of the conduit 1 is usually 1.5 m to 2 m.
A method is used in which two cleats 2 are provided at intervals, fixed to a receiving frame, and pulled in with a wire 3. Therefore, the inside wall of the conduit 1 on the inner side of the bend where the cleat 2 is provided is particularly susceptible to damage due to the sliding of the wire 3, which adversely affects the strength and durability of the conduit 1. There was a problem.

を維持することができる。 That is, this embodiment is a power cable installation method in which a power cable is installed inside a refrigerant transport conduit 1 made of a flexible material. A molded body 4 made of semicircular pipe made of metal or highly rigid plastic and shaped like an arc that fits inside the curved part A of the conduit 1 is removably attached at regular intervals using a tightening fitting 5. The power cable is attached to the pipe and fixed to the frame, and the power cable is led into the conduit 1 by the wire 3 and installed inside the pipe. In this way, when the power cable is drawn into the conduit 1 where the inner wall of the conduit 1 has a smooth circular arc at the bend, the inner wall of the conduit 1 made of a flexible material is Since the power cable can be drawn in and installed inside without causing damage to the wire 3 due to sliding, the original strength and durability of the conduit 1 can be maintained.
