Abstract
The utility model discloses a moisture-proof wire which comprises a conductor. An insulation layer is wrapped on the outer surface of the conductor, and a moisture-proof layer is wrapped on the outer surface of the insulation layer. The insulation layer and the moisture-proof layer of the moisture-proof wire adopt double-layer co-extrusion and are molded in one-shot. Compared with a wire which is provided with a single polrvinyl chloride insulation layer, the moisture-proof wire greatly improves moisture-proof performance, and is the same with the wire provided with a single polrvinyl chloride insulation layer in cost. Meanwhile, the moisture-proof wire greatly improves process technology and processability, and greatly reduces cost. The moisture-proof wire is high in cost performance, and reduces insulation material consumption in unit length by at least 5%, increases carrying capacity by more than 7%, and saves labor by more than 20%. The insulation layer and the moisture-proof layer adopt double-layer co-extrusion and are molded in one-shot.
Description
Technical field
The utility model relates to a kind of moistureproof electric wire, specifically is a kind of use in the protection against the tide of civilian, industrial, commercial, building etc., energy-efficient, moistureproof electric wire and manufacturing approach thereof that cost performance is high.
Background technology
When traditional BV type electric wire used in the environment of civilian, industrial, commercial, building etc., because insulating barrier is a pvc material, it was prone to suction, makes moist easily.The structure of BV type electric wire and material behavior cause electric wire this after long-time use heating, heat can not in time distribute, and that high heat quickens electric wire is aging, thereby causes the electric wire easy fault, causes major disasters such as discharge is hurted sb.'s feelings, fire.And traditional BYJ type electric wire, the unit length consumptive material is big, and cost is high, and cost performance is low, and technology falls behind, and lavishes labor on.
There is following problem in the production technology of traditional BV or BYJ type electric wire: 1) the conductor processing technology falls behind, and can only extrude by individual layer; 2) unreasonable structure of insulating barrier does not have double-layer coextrusion; 3) BV type electric wire insulation layer good permeability, suction, make moist easily, it is aging to quicken electric wire; BYJ type electric wire unit length consumptive material is big, and cost is high, and cost performance is low; 4) waste national resources and social labor power.
The utility model content
The utility model technical problem to be solved provides a kind of novel moistureproof electric wire, and this wire structure is reasonable, and is high greatly in the cost performance that guarantees wire insulation and mechanical performance, and practiced thrift national Limited resources and social labor power.
The described a kind of moistureproof electric wire of the utility model comprises the conductor that electric wire is middle, at conductor outer surface double-layer coextrusion one layer insulating and one deck damp-proof layer.
Said insulating barrier and damp-proof layer are provided with one heart.
Said insulating barrier is the polyvinyl chloride insulation layer, and damp-proof layer is a high density crosslinked polyethylene layer.
Compared with prior art, the beneficial effect of the utility model is:
(1) adopting the sophisticated technologies technology is double-layer coextrusion and concentric mould.
(2) insulating barrier and damp-proof layer adopt double-deck co-extrusion with one heart, disposal molding.
(3) performance of insulating barrier and damp-proof layer has obtained best performance separately, remedies synergy mutually.
(4) unit length insulation consumptive material reduces 5% at least, and ampacity increases more than 7%.
(5) eliminate the production capacity that falls behind, realized the transformation of scientific and technical result, reasonable in design, the product price ratio improves greatly, and labor savings economizes on resources more than 20%, brings benefit to the people.
Description of drawings
Fig. 1 is the structural representation of moistureproof electric wire in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify.
Moistureproof electric wire shown in Figure 1 comprises a conductor 1, conductor 1 outer surface double-layer coextrusion one layer insulating 2 and one deck damp-proof layer 3.According to theoretical and practical condition design, different size, the extrusion die size of double-layer coextrusion is different, and the double-layer coextrusion mould is concentric mould.
The utility model is that the different performance according to insulating layer material and moisture barrier material designs, and insulating barrier and damp-proof layer adopt double-layer coextrusion, disposal molding.Conductor 1 is processed by single electrolysis copper wire or many electrolysis copper wires press strand and process.Insulating material adopts ample supply of commodities on the market, cheap, insulation property and the good pvc material of softness, but this material good permeability, suction; Moisture barrier material adopts the high density cross-linked polyolefin, its molecular structure is network structure, do not absorb water, airtight, insulation property are superior, form the damp-proof layer and the second road insulating barrier, and in this protection against the tide electric wire the material proportion of standing very little.
Come to set forth in detail the manufacturing approach of the described a kind of moistureproof electric wire of the utility model below through a specific embodiment.
Embodiment: making specification is that (specification of 95 expression conductors is 95mm to FC-BVY-450/750V 95
2) the manufacturing approach of moistureproof electric wire, concrete steps are following:
1) cathode copper melting, continuous casting and rolling go out Φ 8.0 mm cathode copper bars;
2) Φ 8.0 mm cathode copper bars carry out wire drawing, anneal and process the soft copper silk of Φ 2.52 mm;
3) the soft copper silk of 19 Φ 2.52 mm is pressed stranded, press mould and adopt nano die, its diameter of bore is 11.6mm, and stranded conductor outermost layer left-hand is stranded;
4) extrude polyvinyl chloride insulation layer and damp-proof layer, adopt the double-layer coextrusion extrusion die, 95mm
2The insulation thickness of inner wire is 1.45mm, and damp-proof layer thickness is 0.15 mm;
5) external diameter of the moistureproof electric wire of finished product is 14.8 mm, the bright and clean rounding of appearance.
All to test whether reach necessary requirement after the above per pass operation.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
