The utility model relates to an improvement of a cluster overhead insulating electric cable, which is characterized in that at least one core in an aluminum wire core in a cluster multi-core type contains a non-magnetic conducting metal pipe which comprises an optical fiber unit inside. Thus, the cluster overhead insulating electric cable simultaneous has the double functions of electric power transmission and optical fiber communication. The electric power transmission, and network and cable television information transmission can be simultaneously obtained by erecting one electric cable. Optical fibers can be laid to countryside families with low cost with the overhead electric cable by making use of the reformation of countryside electric network circuits. The electric cable of the utility model has the advantages of simple manufacture and can distribute the optical fibers in the electric cable in the process of forming the electric cable. Compound cost is low and only optical fiber cost is increased without any other cost. The optical fibers are attached in the sealing non-magnetic conducting metal pipe and the outer layer of the electric cable forms double-layer sealing of insulation to effectively prevent outside moisture from entering. The utility model can be attached in the cluster insulating electric cable to increase the wind resistance of the optical fibers. The utility model can be attached in the cluster electric cable to increase the illegal connecting resistance of the optical fibers in order to enable the safety of the optical fibers to be better than an optical fiber electric cable which is individually laid. Meanwhile, the function of the cluster overhead insulating electric cable is enlarged.
