Abstract
The utility model discloses a power cable, which comprises a conductive wire core, an insulation layer coated on the surface of the conductive wire core and a sheath. The conductive wire core, the insulation layer and the sheath are arranged from the inside to the outside. A full-medium foam filling is also included. The full-medium foam filling is filled in a gap between the sheath and the conductive wire core coated by the insulation layer. Accordingly, the full-medium foam filling power cable is light and the outer diameter of the cable is reduced.
Description
Technical field
The utility model belongs to the electric power transportation art, specifically, relates to the foam filled power cable of a kind of full medium.
Background technology
Wires and cables industry is the supporting industry of the power industry of one of pillars of the national economy industry, occupies extremely important status in national economy.The electric wire product can play the important function of carrying the energy, transmission information, therefore is described as " blood vessel " and " nerve " of national economy.Power cable needs stranding mostly, there is very big space between the core of stranding, need to fill, just can make the cable rounding, packing or gasket for packing, the mode of band are then adopted in traditional filling, filling effect is poor, roundness is restive, and can not fill up the stranding space fully, and waste band material.
Summary of the invention
The purpose of this utility model is to provide in light weight again simultaneously and reduce the foam filled power cable of full medium of the outside diameter of cable behind a kind of filling effect.
The utility model realizes that the technical scheme of above-mentioned purpose is, a kind of power cable, comprise conductor wire core, be extruded in the insulating barrier and the oversheath on conductor wire core surface, described conductor wire core, insulating barrier and oversheath are according to arranging from inside to outside, its improvement is: comprise that also full medium is foam filled, described full medium is foam filled to be extruded in oversheath and to be extruded with in the space between the conductor wire core of insulating barrier.
Described conductor wire core is single or many stranded annealed copper conductors or aluminum or aluminum alloy conductor, and its cross section is 1.5mm
2To 1000mm
2
The core number of described conductor wire core is 1 core to 61 core.
Described full medium is foam filled to be physics or chemical blowing macromolecular material.
Described insulating barrier and oversheath are macromolecular material.
The internal layer of described oversheath can increase copper wire woven shield or armouring or inner covering.
The beneficial effects of the utility model are: owing to also comprise that full medium is foam filled, whole stranding space is crowded with in filling, its filling effect reaches the highest, can improve the rounding property of cable greatly, the deviation in roundness that guarantees cable satisfies customer requirements, fill vertical block-water performance that can improve cable greatly closely, guarantee the operation of cable long-term safety, fill in addition and adopt expanded material, can alleviate the weight of cable, avoid the phenomenon of packing or gasket for packing perk simultaneously, deduct belting layer, the whole cable external diameter is reduced, in light weight, it is convenient that external diameter makes installation lay for a short time.
Description of drawings
Fig. 1 is 3 a core construction of cable schematic cross-sections of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
As shown in Figure 1, a kind of power cable, comprise conductor wire core 1, be extruded in the insulating barrier 2 and the oversheath 4 on conductor wire core 1 surface, described conductor wire core 1, insulating barrier 2 and oversheath 4 are according to arranging from inside to outside, comprise that also full medium is foam filled 3, described full medium foam filled 3 is extruded in oversheath 4 and is extruded with in the space between the conductor wire core 1 of insulating barrier 2.
Described conductor wire core 1 is single or many stranded annealed copper conductors or aluminum or aluminum alloy conductor, and its cross section is 1.5mm
2To 1000mm
2
The core number of described conductor wire core 1 is 1 core to 61 core.
Described full medium foam filled 3 is physics or chemical blowing macromolecular material.
Described insulating barrier 2 and oversheath 4 are macromolecular material.
The internal layer of described oversheath 4 can increase copper wire woven shield or armouring or inner covering.
The foam filled power cable of full medium of the present utility model, can select the cross section of conductor wire core 1 according to actual needs, also can select the core number of conductor wire core 1 according to different equipment needs, can outside becoming cable core, increase copper wire woven shield or armouring and inner covering as required.Product with compact structure, cable roundness height, in light weight, external diameter is little, easily manufactured, technical maturity; Cable installation is also very convenient.When the utility model is made, be manufacture method, behind the cable stranding, adopt plsitive mold, expandable filler is extruded on the stranding cable core,, extrude oversheath again to form the cable core of rounding by common cable.
