Abstract
The utility model discloses a novel electric wire structure, which comprises aluminum core wires and an insulating sleeve which is sleeved on the outer portions of the aluminum core wires, wherein the aluminum core wires have three and are mutually wound around, an asbestos fiber layer is arranged between the aluminum core wires and the insulating sleeve, and the asbestos fiber layer is a fiber screen which is braided by a plurality of transverse asbestos fibers and vertical asbestos fibers. Because the asbestos fiber layer has excellent fire resistance, and further can bear extremely large mechanical impact, the fire resistance of the electric wire can be obviously increased.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, is specifically related to a kind of electric wire that possesses fire retardancy.
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 of this electric wire is relatively poor.
The utility model content
The purpose of this utility model provides the aluminium core 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 New-style electrical wire structure, comprise aluminum core line and be placed in the outer insulating case of aluminum core line, described aluminum core line has three also to curl up mutually, is provided with the asbestos fibre layer between described aluminum core line and the insulating case.
Wherein, described asbestos fibre layer is the fleece that many horizontal asbestos fibres and asbestos fibre braiding longitudinally form.
In addition, described insulating case is polyethylene jacket or polypropylene cover.
The beneficial effects of the utility model are: be provided with the asbestos fibre layer between aluminum core line and the insulating case, the asbestos fibre layer has the good fire resistance energy, can also bear sizable mechanical impact, so 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 New-style electrical wire structure, comprise aluminum core line 1 and be placed in aluminum core line 1 insulating case 2 outward, described aluminum core line 1 has three also to curl up mutually, be provided with asbestos fibre layer 3 between described aluminum core line 1 and the insulating case 2, described asbestos fibre layer 3 is the fleece that many horizontal asbestos fibres and asbestos fibre braiding longitudinally form, and described insulating case 2 is polyethylene jacket or polypropylene cover.
Because asbestos fibre layer 3 has the good fire resistance energy, can also bear sizable mechanical impact, so the fire resistance of the utility model 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)
