Abstract
The utility model discloses a combined sleeve type composite power optical cable with a ground wire, which comprises an optical fiber and a center protecting sleeve. The optical fiber is sleeved in the center protecting sleeve, the center protecting sleeve is a combined structure and consists of at least three pipe pieces, an outer-layer stranded wire is stranded on the outer surface of the center protecting sleeve and comprises aluminum alloy wires and aluminum-clad steel wires which are stranded in a staggered manner at intervals, each aluminum-clad steel wire consists of an aluminum-clad steel stranded wire and a protecting pipe, and the aluminum-clad steel stranded wires are fixedly sleeved in the protecting pipes. The center protecting sleeve adopts a combined structure, consists of a plurality of fan-shaped pipe pieces and is assembled and disassembled conveniently, and the fan-shaped pipe pieces are closely attached to each other under the action of stranding force of the outer-layer stranded wire so as to effectively clamp and fix the optical fiber. In addition, the outer-layer stranded wire consists of the aluminum alloy wires and the aluminum-clad steel wires which are stranded in the staggered manner at intervals, thereby the combined sleeve type composite power optical cable is high in strength and low in mutual interference.
