Abstract
The utility model discloses a novel electric wire, which comprises core wires and a silica gel sleeve which is sleeved on the outer portion of the core wires, wherein the core wires have multiple and are arranged in parallel, and comprise aluminum wires and copper wires, the outer portion of the silica gel sleeve is provided with asbestos fiber sleeves, the outer portion of the asbestos fiber sleeve is provided with a nylon sleeve, and the asbestos fiber sleeves are net-shaped structures which a plurality of transverse asbestos fibers and vertical asbestos fibers. Because the asbestos fiber sleeve has excellent fire resistance, further can bearing 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 New-style electrical 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, comprise heart yearn and be placed in the outer silica gel sheath of heart yearn, described heart yearn has many parallel arranged, constitute by aluminum steel and copper cash respectively, described silica gel sheath is provided with the asbestos fibre cover outward, the outer nylon jacket that is provided with of described asbestos fibre cover.
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 two-layer insulating case, be provided with the asbestos fibre interlayer between the two-layer insulating case, because the asbestos fibre cover has the good fire resistance energy, can also bear sizable mechanical impact, so the fire resistance of this electric wire is promoted obviously.
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, comprise heart yearn 1 and be placed in heart yearn 1 silica gel sheath 2 outward, described heart yearn 1 has many parallel arranged, constitute 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 respectively by aluminum steel and copper cash, described asbestos fibre cover 3 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 asbestos fibre cover 3 has the good fire resistance energy, can also bear sizable mechanical impact, 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)
