A power cable installation structure is provided to protect a power cable inserted into a trough by laying and installing the trough in the ground. A power cable installation structure includes a main body(200), and a cover(300). Internal frames(210,310) are formed by connecting a plurality of supporting blocks(211,311) having penetration holes which penetrate front/rear planes. Wires(220,320) are inserted into the penetration holes and connect the supporting blocks(211,311) with each other. Coatings(230,330) are covered on outer parts of the internal frames(210,310). Concave grooves and protrusions corresponding to the concave grooves are formed on the front and rear planes of the supporting blocks(211,311). The protrusions of the supporting blocks(211,311) are inserted into the concave grooves of the other supporting blocks(211,311). The supporting blocks(211,311) are lifted upward or downward. The penetration holes of the supporting blocks(211,311) are formed to have an inner diameter getting wider from a central part to an end. |
