A cable tray structure of a power transmission line for a condominium complex is provided to absorb electromagnetic waves radiated from a power cable by covering the cable tray with a cover having a copper mesh. Cylinder flanges(20a,20b) have a ground cut portion(21a) and hinge cut portions(21b,21c). Conductive hinge shafts(22a,22b) are inserted into the flanges. A transparent polycarbonate plate(40) has a copper mesh(42) absorbing electromagnetic waves radiated from a power cable. A rectangular flange(44) is coupled to an edge of the polycarbonate plate. Semicircle coupled parts(41a,41b) are laid on upper surfaces of the hinge shaft. Semicircle ground parts(43a,43b) are formed on left and right edge of the copper mesh, and contact the upper surfaces of the hinge shaft. A hinge coupler(50) is installed to left/right ends of the flange. |
