A power cable space structure for a power transmission overhead cable is provided to improve the convenience and safety of the maintenance by preventing the power transmission overhead cable from sagging due to tension variation. A power cable space structure for a power transmission overhead cable includes an upper cable spacer(10), a lower cable spacer(20), a left/right vertical supporting plate(30), and a front/rear sealing plate(40). An upper transmission overhead cable is installed on a semi-circle supporting tube which is formed on the upper cable spacer. An insulated rubber is installed on an inner circumference plane of the semi-circle supporting tube. A couple of front/rear coupling holes are formed on left/right sides of an upper plane of the semi-circle supporting tube. A front/rear supporting ring covers and fixes the upper transmission overhead cable. A plurality of insertion holes are formed on a front/rear front plane of the semi-circle tube. The left/right vertical supporting plate is a plate body which is divided into left/right sides and is vertically installed. The front/rear sealing plate is a rubber plate body which is vertically installed. A semi-circle groove equal to a front plane of the insulated rubber is formed on an upper part of the front/rear sealing plate. The front/rear sealing plate seals and fixes upper/lower parts of front/rear sides of the front/rear vertical supporting plate. |
