Description

A kind of triangle complex controll cable

Technical field

The utility model relates to field of cable technology, particularly relates to a kind of triangle complex controll cable.

Background technology

At present, how the cable of transmission phone, telegram, fax paper, TV and broadcast program, data and other signals of telecommunication, formed by the wire stranding of more than a pair mutually insulated.Telecommunication cable compared with aerial line, have that message capacity is large, transmission stability is high, good confidentiality, less by the advantage such as natural conditions and external influences.

Many round cables are laying in use procedure side by side, can produce gap, take too much land area, cause unnecessary waste.Triangle cable then can change this phenomenon, and this mode is applicable to multi-cable and is arranged in same sleeve pipe.

The cable that the positions such as in prior art, control cables is generally circular configuration, when installing in corner, there will be unstable situation, and being therefore necessary provides one to be adapted at ad-hoc location wall limit, corner are installed; In addition, the conductor of existing triangle cable easily fractures, and owing to being triangular structure, so the rounding property of whole cable requires very high.

Utility model content

The utility model, in order to solve the problem of prior art, provides that a kind of tensile type is strong, stability is high, saves packing material, saves usable floor area, rounding property is good, cost is low reinforced triangular shape complex controll cable.

A kind of triangle complex controll cable described in the utility model, comprises cable core, and described cable core to be triangularly arranged stranded forming by two insulated wire cores and a control conductor; Carbon fiber strengthening core is provided with at the center of cable core; Outside cable core, extrude the triangle twining package tape that thickness is 0.2-0.5mm, triangle twining package tape weaves the armour of 0.4-0.6mm outward, and outermost layer extrudes the triangle oversheath that thickness is 1-1.5mm; Between armour and oversheath, wrapped triangle high strength fibre weaves webbed reinforcement.

Further improvement, described insulated wire cores by conductor, be extruded in the insulating barrier outside conductor and the outer surface be extruded in outside insulating barrier has the layer of tightening of pitch to form.

Further improvement, described control conductor by controlling conductor, be extruded in and control screen outside conductor and the armour be extruded in outside screen is formed.

Further improvement, described insulating barrier is identical with the thickness of screen, is 0.4-0.6mm.

Compared with prior art, the utility model beneficial effect is: (1) traditional multicore cable needs stranding, consumes packing material, and this triangle cable does not need to fill and keeps higher roundness, saves packing material cost and reduces by more than 5%; (2) in the cable between place the stretching resistance that strengthening core can improve cable greatly; (3) between armour and sheath, be provided with one deck high strength fibre and weave webbed reinforcement, contribute to the intensity strengthening cable, tolerance drags wearing and tearing; (4) this whole cable structure triangular in shape, increases the stability of structure itself, saves packing material, saves usable floor area; (5) be provided with outside insulating barrier and fire-resistant tighten layer, protect insulating barrier and not easily at high temperature melt; (6) be provided with outside screen and fire-resistant tighten layer, protect screen and not easily at high temperature melt; (7) thickness of each layer outside cable is all arranged according to strict requirement, makes the rounding property of cable better.

Accompanying drawing explanation

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

Embodiment

A kind of triangle complex controll cable as shown in Figure 1, comprises cable core, and described cable core to be triangularly arranged stranded forming by two insulated wire cores and a control conductor; Carbon fiber strengthening core 7 is provided with at the center of cable core; Outside cable core, extrude the triangle twining package tape 8 that thickness is 0.2-0.5mm, the armour 9 of triangle twining package tape 8 outer braiding 0.4-0.6mm, outermost layer extrudes the triangle oversheath 11 that thickness is 1-1.5mm; Between armour 9 and oversheath 11, wrapped triangle high strength fibre weaves webbed reinforcement 10.

Wherein, described insulated wire cores is that 0.4-0.6mm insulating barrier 2 and the outer surface be extruded in outside insulating barrier 2 have the layer 3 of tightening of pitch to form by conductor 1, the thickness be extruded in outside conductor 1.

Wherein, described control conductor is that 0.4-0.6mm screen 5 and the armour 6 be extruded in outside screen 5 are formed by controlling conductor 4, being extruded in the thickness controlled outside conductor 4.

The utility model embody rule approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
