Description

A kind of high performance electric vehicle charging pile cable

Technical field

This utility model relates to electric wire field, is specifically related to a kind of high performance electric vehicle charging pile cable.

Background technology

Along with the high speed development of novel energy, country will invest huge fund construction charging net, and electric automobile meets new opportunities, and this not only allows electric automobile industry meet new opportunities, also allows its supporting cable industry meet the good market opportunity. No matter it is that charging pile cable will advance wide future from industrial transformation or energy strategy angle. Demand for the charging pile cable of electric automobile also will be greatly increased therewith.

Charging pile cable in use frequently to pull movement, and it is chronically exposed in extraneous adverse circumstances, be vulnerable to greasy dirt burn into sun exposure, the destruction of the severe factor such as automobile rolls, mouse bites, therefore, the performance indications such as oil resistivity, weatherability, resistance to pressure and wearability are had significantly high requirement by charging pile cable.

Utility model content

In order to overcome the deficiencies in the prior art, it is provided that a kind of high performance electric vehicle charging pile cable, cable is made to have good resistance to pressure, weatherability, anticorrosion, weatherability, fire-retardant, Halogen, the characteristic such as unleaded.

For achieving the above object, this utility model provides a kind of high performance electric vehicle charging pile cable, including cable core, described cable core by three for transmit the power cable of charging pile electric energy, two control cable twisting form for the signal-transmitting cable and a signal for controlling charging pile charging signals transmitting charging pile signal; It is provided with rubber filling thing in the gap of cable core, outside cable core, wraps up band, inner sheath, armor and oversheath successively.

Preferably, described power cable forms by the insulated wire cores that the structure that varies in size is identical with signal-transmitting cable, and insulated wire cores is made up of conductor and the insulating barrier being extruded in outside conductor.

Preferably, described signal controls the cable core that cable includes being made up of two mutual stranded insulated wire cores identical with signal-transmitting cable employing, is extruded with isolation strip, copper mesh screen layer and foil shielding layer outside cable core from inside to outside successively.

Preferably, described conductor is strands silver-plated copper conductor.

Preferably, described insulating barrier is polypropylene or polyurethane material composition.

Preferably, described armor is the braiding structure of hot-dip galvanizing steel wire and the uniform mixing of tinned copper wire.

Preferably, described inner sheath is low-smoke halogen-free polyolefin inner restrictive coating.

Preferably, described oversheath is irradiation type low-smoke non-halogen flame-retardant alkene sheath or polyurethane jacket.

The beneficial effects of the utility model are in that:

1, this cable sheath adopts the braiding armouring of the bigger galvanizing jewelry, expensive clothing and other valuables steel wire of count and the uniform mixing of tinned copper wire; both improve the protection to cable core also taken into account bending property and enhanced the electromagnetism interference effect of whole cable core; enhance anti-external mechanical pressure; prevent cable to be bitten by mouse the injury caused in outdoor complicated occasion, extend service life.

2, signal cable screen layer material described in this cable is the tinned copper wire braiding and the wrapped dual shield structure of aluminium foil that count is bigger; not only play the shield effectiveness of excellence; and substantially increase the bending property of cable; it is effectively protected the damage of inner sheath simultaneously, improves the service life of corrosion resistance and cable.

3, this cable conductor adopts strands silver-plated copper conductor structure, monofilament specification is little, and conductor conductivity is high, reduces the diameter of cable from conductor, because have employed silver-plated soft copper conductor strand structure, also ensure that cable has bending property and the conductivity of excellence simultaneously.

4, this cable jacket adopts irradiation type low-smoke non-halogen flame-retardant weatherability polyolefin or polyurethane material, has the anticorrosion of excellence, weatherability, wearability, fire-retardant, Halogen, the characteristic such as unleaded, fully meets charging pile for electric vehicle cable real requirement.

Accompanying drawing explanation

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

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, the amendment of the various equivalent form of values of the present utility model is all fallen within the application claims limited range by those skilled in the art.

As shown in Figure 1, this utility model provides a kind of high performance electric vehicle charging pile cable, including cable core, described cable core by three for transmit the power cable of charging pile electric energy, two control cable twisting form for the signal-transmitting cable and a signal for controlling charging pile charging signals transmitting charging pile signal; It is provided with rubber filling thing 6 in the gap of cable core, outside cable core, wraps up band 7, inner sheath 8, armor 9 and oversheath 10 successively.

Described power cable forms by the insulated wire cores that the structure that varies in size is identical with signal-transmitting cable, and insulated wire cores is made up of conductor 1 and the insulating barrier 2 being extruded in outside conductor.

Described signal controls the cable core that cable includes being made up of two mutual stranded insulated wire cores identical with signal-transmitting cable employing, is extruded with isolation strip 3, copper mesh screen layer 4 and foil shielding layer 5 outside cable core from inside to outside successively.

Preferably, conductor is strands silver-plated copper conductor; The conductor monofilament specification of this structure is little, reduces the diameter of cable from conductor, because have employed the soft copper conductor strand structure of silver-plated copper, also ensure that cable has the bending property electric conductivity of excellence simultaneously.

Preferably, armor is the braid of hot-dip galvanizing steel wire and the uniform mixing of tinned copper wire; Both improve the protection to cable core and also taken into account bending property and enhance the electromagnetism interference effect of whole cable core, enhanced its resistance to pressure, it is therefore prevented that cable had been bitten by mouse the injury caused in outdoor complicated occasion, extended service life.

Preferably, inner sheath is low-smoke halogen-free polyolefin inner restrictive coating.
