Abstract

The utility model provides an OPGW (optical power grounding wire) optical communication cable with fiber optic communication and power grounding double function and is characterized in that a plurality of optical fibers and a plurality of loose pipes form a basic component unit and combine with a gasket for packing and a central reinforcement to form a main communication body, which is covered by a polyimide thermal insulating layer and a seamless aluminum tubing and is skeined by the combination of an aluminum-clad steel wire and an aluminum alloy wire. The utility model has the advantage of convenient construction and is applicable to usage in severe environment.

Description

A kind of Optical Fiber composite overhead Ground Wire

Technical field

The utility model belongs to communication and power domain.Exactly, be a kind of communications optical cable and electric power lightning conducter to be combined, have a kind of composite cable of optical fiber communication and dual-use function power ground concurrently.

Background technology

The Optical Fiber composite overhead Ground Wire of the eighties as Britain BICC company product, adopts multimode fiber, and fiber count is less, and message capacity is little, and diameter is bigger; Aluminum pipe as light unit sheath has the crack, and is not good enough to the barrier properties of water, dirt; The top layer when mixing strand, can make the single line unbalance stress with aluminium-clad steel wire or aluminium alloy wire, influences serviceability and life-span.

Summary of the invention

The utility model is that a kind of monomode fiber that adopts a greater number will be provided, and improves message capacity; With the protective layer of seamless aluminium tubing, optical fiber is played excellent protection as fiber unit; The skin of cable with aluminium-clad steel wire and aluminium alloy wire by stranded after the principle combinations, make stressed evenly, thereby a kind of Optical Fiber composite overhead Ground Wire that increases the service life.

The utility model is realized in the following manner:

Coat the multifiber 2 that evenly is full of greasy for preventing water 3 all around with plastic sheath 1, form loose sleeve pipe 5.After many loose sleeve pipes 5 and gasket for packing 4 combinations, stranded around central reinforce member 6 symmetrically, constitute well-balanced line family, successively by thermal insulation layer 7, seamless aluminium tubing 8 coats, and is closely twisted alclad pipe 8 and form at skin by many wires 9.Multifiber 2 can adopt 2-24.Many loose sleeve pipes 5 are 1-10.Thermal insulation layer 7 is to adopt polyimide film.Many wires 9 are realized by following five kinds of constituted modes: one, be aluminium alloy wire 11 and aluminium-clad steel wire 10 quantity half and half, and alternately arrange (as Fig. 2); Two, be separated with an aluminium alloy wire 11 (as Fig. 3) between per two aluminium-clad steel wires 10; Three, be separated with an aluminium alloy wire 11 (as Fig. 4) between per 3 aluminium-clad steel wires 10; Four, be separated with an aluminium alloy wire 11 (as Fig. 5) between per 5 aluminium-clad steel wires 10; Five, many wires all are aluminium-clad steel wire 10 (as Fig. 6);

Embodiment

Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described further.

Simple optical fiber 2 is through once becoming colored optical fiber after the lining, as required 2-24 root colored optical fiber is twisted into one group, and filling greasy for preventing water 3, form loose sleeve pipe 5 by protecting pipe 1 coating, many loose sleeve pipes 5 and gasket for packing 4 combinations are twisted into shaped fiber unit around center non-metal reinforcement member 6, coat successively more subsequently and go up polyimides thermal insulation layer 7, extrude seamless aluminium tubing 8 by extrusion equipment, and use by aluminium alloy wire 11 and aluminium-clad steel wire 10 summations to be 12, closely to twist alclad pipe 8 at skin with five kinds of different constituted modes.
