Description

A kind of electric automobile charging pile cable

Technical field

This utility model relates to a kind of power cable, the electric automobile charging pile cable that particularly relate to a kind of high oil resistant, can repeatedly roll.

Background technology

Along with electric automobile field is vigorously supported by country, the demand of charging pile cable is the most quickly gone up.Existing charging pile cable travelling performance is poor, it is impossible to adaptation is moved frequently and vehicle rolls, also due to charging station is the most all built near gas station or inside gas station now, so the oil resistivity for cable also has the highest requirement.In place of these problems are all the deficiencies in the prior art.

Summary of the invention

For the shortcoming overcoming above-mentioned prior art to exist, the purpose of this utility model is to provide a kind of and integrates discharge and recharge, the oil resistant of pre-alarming control system, the electric automobile charging pile cable that can repeatedly roll.

In order to solve the problems referred to above, this utility model is by the following technical solutions: this utility model electric automobile charging pile cable, including power line, ground wire, holding wire, there is implant in described power line, ground wire, the stranded rear space of holding wire, being enclosed with band and oversheath outside described implant successively, its contribution is: described power line is two, ground wire one, holding wire one；The conductor of described power and ground is that many copper wires are stranded to be formed, and the outer wrapped polyester belt of described conductor has extruded the elastic body insulated material of high-performance thermoplastic outside described polyester belt；Described holding wire conductor is that many copper wires are stranded to be formed, the elastic body insulated material of holding wire high-performance thermoplastic has been extruded outside described holding wire conductor, extrude sheath after the conductor strand of described tape insulation material, outside described sheath, be disposed with holding wire band, holding wire sheath, holding wire screen layer.

Described implant is non-hygroscopic polypropylene rope.

Described oversheath is polyester-type Polyurethane Thermoplastic Elastomer rubber outer protection set.

The beneficial effects of the utility model are: this utility model electric automobile charging pile cable integrates discharge and recharge, pre-alarming control system, and simple in construction is easy to use；Material and the design of product structure that insulation of the present utility model and sheath use are fully able to bear moving repeatedly and rolling of finished cable；Sheath material has high oil resistivity, can relieved use in oiliness environment.

Accompanying drawing explanation

With embodiment, this utility model is described further below in conjunction with the accompanying drawings:

Fig. 1 is the structural representation of this utility model one embodiment；

In figure: 1, conductor, 2, polyester belt 3, the elastic body insulated material of high-performance thermoplastic, 4, implant, 5, holding wire conductor, 6, the elastic body insulated material of holding wire high-performance thermoplastic, 7, sheath, 8, holding wire band, 9, holding wire sheath, 10, holding wire screen layer, 11, band, 12, oversheath.

Detailed description of the invention

As it is shown in figure 1, this utility model electric automobile charging pile cable, including power line two, ground wire one, holding wire one；The conductor 1 of described power and ground uses the 6th kind of conductor in " conductor of GB T 3956-2008 cable ", forms for many copper wires are stranded；The wrapped one layer of polyester belt 2 of difference on conductor after strand system, the rate of putting up of every layer of polyester belt 2 is 10-15%, thus ensure that conductor can be wrapped up by polyester belt, plays the effect that conductor is isolated in insulation；Having extruded the elastic body insulated material of high-performance thermoplastic 3 outside described polyester belt, extruded the elastic body insulated material of high-performance thermoplastic 3 by extruding machine twisting on conductor processed, extruder screw needs the employing compression ratio to be: the screw rod of 1:2.5 ~ 1:3.2.

Described holding wire conductor 5 forms for many copper wires are stranded, has extruded the elastic body insulated material of holding wire high-performance thermoplastic 6, then the insulated wire cores pair twist on pipe twisting machine that will make outside described holding wire conductor 5；Having extruded sheath 7 after the conductor strand of described tape insulation material, sheath 7 is coated on that stranded core is outer and the space of filling up between cable core is so that cable rounding, it is ensured that holding wire is not deformed by extraneous all directions mechanical force；Being disposed with holding wire band 8, holding wire sheath 9, holding wire screen layer 10 outside described sheath, holding wire screen layer 10 uses the copper wire of a diameter of 0.15mm to weave on braider, and density is more than 80%.

Described power line, ground wire, holding wire use on cable-former and are arranged in order stranding clockwise, and holding wire is put finally, and stranded rear space is filled by non-hygroscopic polypropylene rope implant 4, prevents external strength from making core move；Described implant 4 is outer is enclosed with band 11 and polyester-type Polyurethane Thermoplastic Elastomer rubber outer protection set 12 successively, extruding machine is by melted Polyurethane Thermoplastic Elastomer rubber, extrude coated to becoming on cable core, form outermost layer oversheath 12, power wire core and holding wire being encapsulated in sheath, sheath extruding machine screw rod needs to use the compression ratio be: the autocratic screw rod of 1:2.0 ~ 1:3.0.

This utility model is not limited only to above-described embodiment.
