Abstract
The utility model discloses an insulating nylon sheath wire and cable of fire -retardant polyvinyl chloride, the conductor unit of being in the same place including polyvinyl chloride oversheath and a plurality of inseparable range, the cladding of polyvinyl chloride oversheath is a plurality of the conductor unit is outside, it has the filling layer to fill between the conductor unit, the conductor unit is by interior conductor, polyvinyl chloride insulating layer and the nylon restrictive coating of being in proper order outside to. This cable oil resistivity, wearability and ageing resistance can be good, difficult emergence short circuit.
Description
Technical field
The utility model relates to a kind of electric wire, is specifically related to a kind of flame-proof polyvinyl chloride insulated nylon protective case wire cable.
Background technology
Polyvinyl chloride insulating nylon sheathed wire is widely used in the U.S., South America, Europe, the Middle East, the technical performance of its excellence, the economic benefit of material benefit, be convenient to transport and the feature of construction and installation, to progressively replace BLV in fields such as building (particularly skyscraper), automobile, electric equipment and household electrical appliance, market potential is huge.Along with the fast development of China's modernization construction cause and improving constantly of people's living standard, require the concern having caused government and the public for using the environmental protection security performance of electric wire in building, household electrical appliance.
For a long time, China's indoor power line wiring for building adopts BV type or the BVV type cotton covered wire of PVC insulation always., there is overload capacity because its Insulation Material is common polyvinyl chloride in the electric wire of this traditional structure and short circuit thermal capacity is little, can not tolerate higher ambient temperature; Polyvinyl chloride insulation is heated and can shrinks simultaneously, affects the fail safe of circuit working; Electric wire oil resistance is poor, wear no resistance, ageing resistace is poor.Easy damaged insulating barrier during cable installation in pipe, when circuit overload operation, temperature exceed prescribed limit and burn out insulation, forms potential short circuit and fire hazard hidden danger.
Utility model content
For solving above-mentioned prior art Problems existing, the utility model proposes a kind of flame-proof polyvinyl chloride insulated nylon protective case wire cable, this cable oil resistance, resistance to wear and ageing resistace are good, are not easily short-circuited.
The technical solution of the utility model is achieved in that
A kind of flame-proof polyvinyl chloride insulated nylon protective case wire cable, comprise polyvinyl chloride oversheath and some close-packed arrays conductor element together, it is outside that described polyvinyl chloride oversheath is coated on some described conductor elements, is filled with packed layer between described conductor element; Described conductor element is followed successively by conductor, polyvinyl chloride insulation layer and nylon sheath wire layer from inside to outside.
Further, described conductor is copper core conductor.
Further, the quantity of described conductor element is 3.
Further, as the described outside diameter of cable≤25mm, the described cable bend Ban Jing≤4 times described outside diameter of cable.
Further, as described outside diameter of cable >25mm, the described cable bend Ban Jing≤6 times described outside diameter of cable.
The beneficial effects of the utility model:
The conductor element of flame-proof polyvinyl chloride insulated nylon protective case wire cable of the present utility model is followed successively by conductor, polyvinyl chloride insulation layer and nylon sheath wire layer from inside to outside, and wherein nylon sheath wire layer just in time compensate for the shortcoming of polyvinyl chloride insulation layer; Further, overcome nylon layer at the outside coated one deck polyvinyl chloride oversheath of described conductor element and have that cost is high, water absorption large, affect the problem such as dimensional stability and electrical property, both respectively get the chief at complementation, meet green, environmental protection, safe requirement.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model flame-proof polyvinyl chloride insulated nylon protective case wire cable;
Accompanying drawing indicates: 1, conductor element, and 2, polyvinyl chloride oversheath, 3, packed layer, 101, conductor, 102, polyvinyl chloride insulation layer, 103, nylon sheath wire layer.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of flame-proof polyvinyl chloride insulated nylon protective case wire cable, comprises polyvinyl chloride oversheath 2 and 3 close-packed arrays conductor element 1 together.It is outside that described polyvinyl chloride oversheath 2 is coated on 3 described conductor elements 1.Packed layer 3 is filled with between described conductor element 1.Described conductor element 1 is followed successively by conductor 101, polyvinyl chloride insulation layer 102 and nylon sheath wire layer 103 from inside to outside.Conductor 101 is preferably copper core conductor.
Further, in the present embodiment, during the outside diameter of cable≤25mm, the cable bend Ban Jing≤4 times outside diameter of cable; As outside diameter of cable >25mm, the cable bend Ban Jing≤6 times outside diameter of cable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
