Abstract

The utility model discloses a high-strength fiber composite low-voltage cable. The cable comprises a cable core. The cable core is formed by twisting a plurality of insulation wire cores which are composed of conductors and insulation layers wrapped outside the conductors in an extruding manner; the gap of the cable core is filled up with a filling band; the cable core is successively wrapped by an inner sheath, an armor layer and an outer jacket; and the conductors are light unit assembly structures and are formed by twisting light units and a plurality of metal wires wrapped outside the light units. The high-strength fiber composite low-voltage cable has the advantages of excellent mechanical property, high reliability, easy laying and the like. Besides, by adopting a combination structure of fibers and power wire cores, the construction workload is reduced and the construction period is shortened; steel loose sleeves, conductor-use metal monofilaments and the armor layer are utilized for simultaneously protecting the light units, so that the mechanical property of the light units are better protected, the problem that the light units are easily damaged is well solved, and electric energy transmission is not affected at the same time.

Description

A kind of high strength optical fiber composite low-voltage cable

Technical field

the utility model belongs to power cable, optical communication field, is specifically related to a kind of high strength optical fiber composite low-voltage cable.

Background technology

Along with national grid and south electric network strengthen the construction to intelligent grid, except backbone network is built high pressure, superhigh pressure large capacity transmission circuit energetically, at user side, try hard to recommend power optical fiber to family.Power optical fiber refers to family, in low pressure communication, connects

In networking, adopt optical fiber composite low-voltage cable that optical fiber is laid with lv power cable, thereby realize that intelligent electric meter is to family, coordinate passive optical network technique, the business such as the collection of carrying power information, intelligent power two-way interactive, the fusion of many nets.It is few that at present China cable producer can research and develop and produce the enterprise of optical fiber composite low-voltage cable, and all cable core all adopts many power and an optical cable to combine, although this spline structure is simple, because the power line core conductor adopts metal material, and the optical cable employing is all nonmetallic materials, therefore optical fiber composite low-voltage cable light unit in manufacture and use procedure is subject to the damage of external influence power, causes optical fiber composite low-voltage cable normally to move, and even scraps.

The utility model content

The purpose of this utility model is to provide that a kind of mechanical performance is high, reliability is high, is easy to the optical fiber composite low-voltage cable of construction.

A kind of high strength optical fiber composite low-voltage cable described in the utility model, comprise cable core, its cable core by some by conductor and be extruded in stranded the forming of power core that the outer insulating barrier of conductor forms, gap at cable core is provided with filling tape, coats successively inner sheath, armour and outer jacket outside cable core; Described conductor is light unit combination body structure, is by the light unit and is coated on stranded the forming of many one metal wires outside the light unit.

Further improve, described smooth unit is by optical fiber and be coated on the outer steel pine sleeve pipe of optical fiber and form.

Further improve, between described optical fiber and steel pine sleeve pipe, also fill cable cream, optical fiber excess length is controlled between 4 ‰ to 6 ‰.

The beneficial effects of the utility model are:

The utility model coats the layer of metal conductive monofilament and, at cable outer cladding one deck armour, makes the light unit obtain the three-layer metal protection after optical fiber coats steel pine sleeve pipe, thereby solved the easily impaired problem by external force of optical fiber.All coat a light unit in each root conductor, guaranteed the stressed uniformity of every light unit, thereby reach the stability of structure.The combination of light unit and power core is easy to the residential quarter electric energy and signal equipment lays simultaneously, has reduced the construction working amount, has reduced the construction period, has saved project cost, has reduced cost.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, a kind of high strength optical fiber composite low-voltage cable described in the utility model, comprise cable core, its cable core by some by conductor and be extruded in stranded the forming of power core that the outer insulating barrier 4 of conductor forms, be provided with filling tape 8 in the gap of cable core, coat successively inner sheath 5, armour 6 and outer jacket 7 outside cable core; Described conductor is light unit combination body structure, is by the light unit and is coated on stranded the forming of many one metal wires 3 outside the light unit.Described smooth unit is by optical fiber and be coated on the outer steel pine sleeve pipe of optical fiber and form.Also fill cable cream between described optical fiber 1 and steel pine sleeve pipe 2, the remaining length of optical fiber 1 is controlled between 4 ‰ to 6 ‰.

The utility model provides a kind of high strength optical fiber composite low-voltage cable; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
