PURPOSE:To fix a half corrugated plastic tube to supporting parts together with a communication cable body, and to eliminate deterioration in radio wave coupling, and to facilitate laying work, by installing the half corrugated plastic tube on the side of the cable body which faces a high speed train. CONSTITUTION:The communication cable body 6 is installed over a railroad track for high speed train at enough height for communication, and fixed to supporting bodies 3. The side of the cable body 3 which faces said train is covered and the half corrugated plastic tube 7 is fixed to the supporting bodies 3 by fixing means 4 together with the cable body 6 via interposing spacers 8 are provided between the both. The cable body 6 is protected by the plastic tube 7, the fixation of the cable body 6 is facilitated, and stress applied to connection parts of the cable body 6 is reduced. Further, the deterioration in radio wave coupling is prevented and the laying construction is simplified. |
