<p>The present invention provides an electrical cable for the mine dump truck. The electrical cable comprises conductive piece and insulating layer; the insulating layer is surrounded around the conductive piece; the conductive piece is stranded by inner conductors and outer conductors, the inner conductors are made of copper alloy, the outer conductors are made of copper. The electrical cables used in the mine dump truck withstand high oscillation, repeated drag and stretching in the work environment and has high demand for power transmission. Compared with the conventional cables, the electrical cables of the present invention have better efficiency, carrying capacity and security. Drawings Figure 1</p> |
