Abstract
The utility model discloses a non-heat-treated aluminium alloy overhead insulation cable. The cable successively comprises a conductor, a semiconductor shielding layer and an insulating layer or comprises a conductor and an insulating layer from inside to outside. The conductor is intertwisted concentrically by non-heat-treated aluminium alloy molded single wires which are no less than 58.5% in terms of conductivity according to IACS, and the filling coefficient of the intertwisted conductor is not less than 93%. The conductor is intertwisted concentrically by the non-heat-treated aluminium alloy molded single wires which are no less than 58.5% in terms of conductivity according to IACS, so that the conductor is soft, round, smooth and tight. Therefore, the whole cable is light in weight, high in strength and low in sagging, can transmit high-capacity current, can meet different usage occasions, is energy-saving and environment-friendly, and has a quite wide market prospect.
Description
Technical field
The utility model relates to a kind of non-heat-treatable aluminum alloy aerial insulated cable, the aerial insulated cable in replaceable existing market.
Background technology
Aerial insulated cable just came out as far back as last century, and brought into use in countries such as Europe, Japan and the United States, and facts have proved for many years uses aerial cable can improve power supply reliability, minimizing accident number of times.To so far, aerial insulated cable is widely used.
The conductor of aerial insulated cable mainly adopts copper, aluminium, aluminium alloy, steel reinforced aluminium conductor.Wherein therefore front technique manufacturing is difficult for aluminium alloy, generally all need heat-treat, and involves great expense, and conductance is low, fails to be widely used.Copper conductor is restricted by price and weight also, and the market utility ratio is low.The aerial insulated cable that uses in the market is in the majority with aluminium core and steel reinforced aluminium conductor, does not adopt molded line.
Fine aluminium conductor intensity is lower, and is less at span, and the more abundant occasion of the space passage is used more, is generally rural subscribers' distribution.And when design, consider the intensity of conductor, substantially all be partial to and use the steel reinforced aluminium conductor conductor, but payingoff construction is loaded down with trivial details.
In process of production, no matter be fine aluminium conductor or steel reinforced aluminium conductor conductor, all adopt conductor compacting technique.Easily cause conductive surface crude, in the aluminium wire gap, the aluminium bits are piled up.Easily carry the aluminium bits secretly in follow-up insulating exruded technique.Finished product punctures more when doing voltage test, has a strong impact on product percent of pass.
In actual use procedure, investigation for many years proves, aluminum cable steel reinforced aerial insulated cable weight is excessive, and during large span hanging wire, sag is larger.Especially when present municipal construction, the space passage is compact, and during one-sided three-phase unwrapping wire, sag is excessive easily to be caused wind to hit to wave, the cable collision, and safety is used in impact.
The utility model content
The purpose of this utility model is the bottleneck that runs in and use not enough for existing aerial insulated cable, and a kind of excellent performance, lightweight is provided, and sag is little, can satisfy different use occasions, the non-heat-treatable aluminum alloy aerial insulated cable of energy-conserving and environment-protective.
The technical scheme that realizes the utility model purpose is a kind of non-heat-treatable aluminum alloy aerial insulated cable, comprises successively from the inside to the outside conductor, shield semiconductors layer and insulating barrier or is from the inside to the outside conductor and insulating barrier; It is the non-heat-treatable aluminum alloy molded line single line concentric stranding that is not less than 58.5%IACS that described conductor adopts conductance, and the activity coefficient of stranded conductor is not less than 93%.
Described shield semiconductors layer is 6kV and above cross-linking type or non-crosslinked type.
Cable is conductor and insulating barrier from the inside to the outside; Described insulating barrier is the weather-proof material of black.
Adopted technique scheme, the utlity model has following beneficial effect: compared with prior art, non-heat treatment molded line aluminium alloy aerial insulated cable of the present utility model, aluminium alloy conductor intensity 〉=240MPa, conductance 〉=58.5%IACS, adopt molded line cold-drawing process technology leading in the world at present, the stranded conductor activity coefficient is reached more than 93%, so conductor softness, rounding, tight.Prove through lot of experiments, the non-heat treatment molded line aluminium alloy conductor of equivalent diameter is compared with the steel reinforced aluminium conductor conductor, and when the former conductor pull-off force and 20 ℃, D.C. resistance all is better than the latter.Conductor is piled up without the aluminium bits when follow-up extrusion technique, can realize cleaner production.And the conductive surface rounding, the test percent of pass is high.Whole cable is lightweight, intensity is high, sag is little, can the transmission of large capacity electric current, can satisfy different use occasions, and energy-conserving and environment-protective, market prospects are boundless.
