Abstract
The utility model discloses an electric wire, which comprises a core wire and a silica gel sleeve sleeved outside the core wire, wherein the core wire adopts two aluminum wires arranged in parallel and a copper wire, an asbestos fabric sleeve is arranged outside the silica gel sleeve, a nylon sleeve is arranged outside the asbestos fabric sleeve, a layer of mica paper is arranged outside the nylon sleeve, and the asbestos fabric sleeve adopts the reticular structure formed by a plurality of transverse asbestos fabric and longitudinal asbestos fabric woven together. Because the asbestos fabric sleeve is arranged outside the core wire, the core wire can bear great mechanical impact; the layer of mica paper is arranged outside the nylon sleeve, so as to achieve excellent fire resistance; and two layers of insulation sleeves are alternately arranged, so that the inflaming retarding performance of the electric wire is apparently upgraded.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, is specifically related to a kind of low tension wire.
Background technology
Electric wire is the lead of conduction current, is mainly used in electric power, communication and correlated current transmission field, and it mainly is made up of conductor core wire and the outer insulating case of heart yearn.Electric wire was as conductor with copper cash in the past, but the price comparison costliness of copper, make that the cost of electric wire is higher, in the last few years, in order to reduce cost, electric wire with other metal material Alloy instead of Copper has appearred, aluminium more commonly, aluminium is suitable as the electric wire performance and the copper of heart yearn, but price but reduces greatly, be subjected to welcoming widely, but the fire resistance and the anti-collision performance of this electric wire are relatively poor.
The utility model content
The purpose of this utility model provides the electric wire that a kind of fire resistance obviously promotes.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric wire, comprise heart yearn and be placed in the outer silica gel sheath of heart yearn, described heart yearn is two aluminum steels and copper cash of parallel arranged, described silica gel sheath is provided with the asbestos fibre cover outward, described asbestos fibre cover is outer to be provided with nylon jacket, and described nylon jacket is provided with one deck mica paper outward.
Wherein, described asbestos fibre cover is the network structure that many horizontal asbestos fibres and asbestos fibre braiding longitudinally form.
In addition, described copper cash is tin-coated copper or nickel-clad copper.
The beneficial effects of the utility model are: heart yearn is provided with the asbestos fibre cover outward, can bear sizable mechanical impact, nylon jacket is provided with one deck mica paper, has the good fire resistance energy, add the two-layer insulating case that is arranged alternately, the fire resistance of this electric wire is obviously promoted.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 1, a kind of electric wire, comprise heart yearn 1 and be placed in heart yearn 1 silica gel sheath 2 outward, described heart yearn 1 is two aluminum steels and copper cash of parallel arranged, the described silica gel sheath 2 outer asbestos fibre covers 3 that are provided with, the described asbestos fibre cover 3 outer nylon jacket 4 that are provided with, the described nylon jacket 4 outer one deck mica paper 5 that are provided with, described asbestos fibre cover is the network structure that many horizontal asbestos fibres and asbestos fibre braiding longitudinally form, and described copper cash is tin-coated copper or nickel-clad copper.
Because the heart yearn 1 outer asbestos fibre cover 3 that is provided with can bear sizable mechanical impact, nylon jacket 4 is provided with one deck mica paper 5, has the good fire resistance energy, add the two-layer insulating case that is arranged alternately, so the fire resistance of this electric wire is promoted obviously.
The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
Claims (3)
