Description

A kind of pull-up cable of highly resistance

Technical field

The utility model relates to field of cables, and in particular to a kind of pull-up cable of highly resistance.

Background technique

It is well known that the radiation installation of cable is all that traction progress is carried out by external force, especially outdoor long length Power cable, it is generally the case that the actinobacillus device of construction site be all passively, can not active unwrapping wire, and be all it is easy, So cable needs very big external force that can just be pulled gradually mounting and installation, this when if it is small bore especially Aluminium cable, the external tensile force of unbearable overload just will appear conductor and be attenuated or even be pulled off and the structures such as insulating layer There is a situation where being broken, after the installation is completed to cable laying, through detection the performances such as whole cable no power or insulation resistance without Method meets the requirement that safe operation uses, and at this time has to look for the position of fault, carries out reparation of doing over again, but will occur when serious whole The phenomenon that root cable is broken many times, at this time the searching of either fault point still do over again reparation be all it is extremely difficult, make At very huge economic loss and serious schedule delays.So the exploitation pull-up cable of highly resistance, avoids the occurrence of and is pulled off, draws and attenuates, insulating The phenomenon that structural breaks such as layer, it is ensured that the stable operation of all line securities is the task of top priority.

Find there is colleague to invent a variety of tensile type cables, such as Chinese patent ZL201220283764.2 is adopted through retrieval With wire armor is coated in inner sheath side, such structure reduces the bending of cable while increasing tensile capacity Performance also considerably increases the weight and manufacturing cost of cable；For another example Chinese patent ZLCN201420493629.X is used Tension hole is set outside insulating layer, then copper wire is installed in tension hole as reinforcer, such structure increases cable Outer diameter also reduces the bending property of cable, and the structure in tension hole also can cause to damage to insulating layer, to insulating performance of cable Stability has an adverse effect, while mechanical external force when copper wire can not also carry installation as tensile reinforcement member, especially electric power The environment of cable field laying；Therefore it is simple and practical to need to develop one kind, is easy production, reduces cost and be able to bear larger The pull-up cable application of the highly resistance of mechanical tensile forces is in use in special circumstances.

In order to avoid the lesser cable in section, generated after especially aluminium cable is in laying installation by the traction of external force Cable body be extended, the structure of conductor changes, and insulating layer etc. is broken, cable cannot according to design stability run or Be unable to operate normally, and such case in the use of cable frequent occurrence, bring about great losses, this cable is widely used in The every field of cable transfer.

Utility model content

Goal of the invention: in order to overcome the deficiencies in the prior art, a kind of high tensile cable is provided, cable is improved Intensity and flexibility.

Technical solution: to achieve the above object, the utility model provides a kind of pull-up cable of highly resistance, including cable core, described Cable core be triangularly arranged by three insulated wire cores, three insulated wire cores be twisted center at fill etc. radians reinforce The outermost surface of muscle, three arc sides and three insulated wire cores of the reinforcing rib fits closely；Three insulated wire cores two Superficies correspondence between two fits closely three arc reinforcers, and three arc reinforcers are spliced into circle；In three arcs Cable core is tightened by wrapped multilayer binding tape outside reinforcer, the compound outer jacket outside binding tape；The insulated wire cores are by leading Body layer and the insulating layer being extruded in outside conductor layer are constituted；The conductor layer is reinforced by central tensile reinforcer and with tension The conductor monofilament composition being centered around centered on part outside tensile reinforcement member.

Further, the described equal radians reinforcing rib is steel type reinforcing rib, can carry the mechanical force of cable.

Further, the arc reinforcer is PC plastic reinforcer, and cable core is prevented to be extruded.

Further, the tensile reinforcement member includes continuous basalt fiber, glass fibre, carbon fiber and resin matrix, Continuous basalt fiber, glass fibre and carbon fiber are compounded on resin matrix.

Further, the compound outer jacket includes inner sheath and oversheath, is compiled between the inner sheath and oversheath Knit steel-tape armouring layer.

Further, the conductor monofilament is copper wire, aluminum-alloy wire or aluminium wire.

Compared with prior art, the utility model has the beneficial effects that:

1, this cable from conductor to cable core use different reinforcers so that cable have very strong pull resistance, anti-extrusion, Bearing capacity, solves the lesser cable in section, generates electricity after especially aluminium cable is in laying installation by the traction of external force Cable ontology is extended, and the structure of conductor changes, and insulating layer etc. is broken, and cable cannot be run according to design stability or nothing Method operate normally, and such case in the use of cable frequent occurrence, the problem of bringing about great losses, the cable be widely applied In the every field of cable transfer；

2, conductor reinforcer is due to being compounded on resin matrix by continuous basalt fiber, glass fibre and carbon fiber, Continuous basalt fiber greatly enhances the intensity of reinforcer, and carbon fiber and glass fibre increase the flexibility of reinforcer, by this plus Strong part is stranded on existing cable, plays the role of an absorbability, in bending cable and when pullling cable, these power all by It marries again on reinforcer, by the effect of reinforcer, substantially increases the intensity and flexibility of cable；

3, continuous basalt fiber, glass fibre and carbon fiber are compounded in the distribution form on resin matrix are as follows: triangle It is distributed, forms a complementation between three, form one mutually and pull power, increase the intensity and toughness of reinforcer；

4, using compound outer jacket, although structure does not change, extruding in layer before ratio reduces production journey Sequence.
