Description

A kind of copper-clad steel cable

Technical field

This utility model relates to field of cable technology, particularly to a kind of copper-clad steel cable.

Background technology

The existing construction of cable includes many conductors, is coated on the insulating barrier outside each conductor, braid and restrictive coating Four parts, wherein, conductor constitutes insulated wire cores with insulating barrier.

At present, the conductor of most of cables is made up of bare copper wire, and the material that restrictive coating uses is common igelite, Its deadweight of this cable is relatively big, and copper product usage amount is big, and cost is of a relatively high.The cable tensile strength of this structure is poor, leads Body is susceptible to fracture, and restrictive coating pliability is poor, in big span, the area of seriously corroded, and the power cable tool of this routine There is significant limitation, easily damaged, shorten the service life of cable.It addition, bear the environment of alternating bending at automobile etc. Under, the cable of use does not require nothing more than high bending durability, and from the viewpoint of easily carrying out distribution, also require that high can Flexibility, existing cable still can not realize high bending durability and high pliability simultaneously, thus reduce the environment of cable Adaptability.It addition, in the most mobile, when equipment is near power line, need to store cable, when equipment is away from power supply Time, cable to be unfolded and come, in this process, cable is not only pulled pulling force or the thrust of effect, and produces electricity The bending stress of cable and the distorting stress of the axis along cable, common cable, in contraction process, can produce random direction Winding, sometimes cable can tied up in knots, the phenomenon such as cause partial points bending radius too small, due to bending stress and the torsion of cable The frequent cross occurrence of turning stress, thus have a strong impact on the service life of cable.

Utility model content

The problem that the purpose of this utility model is to exist for prior art, it is provided that a kind of can reduce disappearing of copper material Consumption, there is electric conductivity as copper conductor, the construction of cable with stronger tensile property.

For the attainment of one's purpose, the technical scheme that this utility model provides is:

A kind of copper-clad steel cable that this utility model relates to, it includes some cable core unit and successively around wrapping in cable core unit The stranding band in outside, inner sheath, shield, oversheath, be filled with filling in the space between cable core unit and stranding band Material, it is characterised in that: described cable core unit includes the steel strand wires twisted together by least two steel wires, the periphery of steel strand wires It is provided with outer copper-clad, lapped insulation band outside outer copper-clad.

Preferably, described outer copper-clad is plated in the outside of steel strand wires uniformly.

Preferably, described shield layer uses welding wire braiding sheathed structure.

Described oversheath is made up of thermoplastic elastic material.

Described packing material is made up of resin.

The technical scheme using this utility model to provide, compared with prior art, has the advantages that

The copper-clad steel cable steel core that this utility model relates to replaces the use of a part of copper, greatly reduces the damage of copper material Consumption, cost is cheaper, owing to copper covered steel conductor is soft, plays electric action or steel core surface layers of copper, therefore its conduction Performance is preferable as bare copper conductor, but mechanical strength is better than bare copper conductor, can meet big span or across requirements such as rivers.

Detailed description of the invention

For further appreciating that content of the present utility model, this utility model is described in detail in conjunction with the embodiments, real below Execute example for this utility model is described, but be not limited to scope of the present utility model.

With reference to shown in Fig. 1, a kind of copper-clad steel cable that this utility model relates to, it includes five cable core unit 1, fills material Material 2, stranding band 3, inner sheath 4, shield 5 and oversheath 6.

Described cable core unit 1 includes the steel strand wires 11 of center, and steel strand wires 11 are twisted together by two steel wires, and steel twists The outside copper facing of line 11 forms outer copper-clad 12, the outside lapped insulation band 13 of outer copper-clad 12.Five described cable core unit 1 are adopted It is bundled into a branch of with stranding band 3, in the space between cable core unit 1 and stranding band 3, fills up packing material 2, described filling Material 2 is made up of resin.The most wrapped inner sheath 4 and oversheath 6 outside stranding band 3, wherein oversheath is by thermoplastic elastic Body material is made, and arranges shield 5 between oversheath 6 and inner sheath 4, and described shield uses welding wire braiding armour Assembling structure, is mainly used in existing mechanical shock, has again electroacoustic to disturb higher mine gallery and inclined gallery to make main signal transmission, profit Constituting armor by the intensity of steel core can prevent mechanical shock from causing damage cable, and having reached two kinds with a kind of composite should Use effect.

Above in association with embodiment, this utility model has been described in detail, but described content be only of the present utility model relatively Good embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range Impartial change and improvement etc., within all should still falling within patent covering scope of the present utility model.
