Abstract

The invention discloses a carbon fiber copper core alloy wire spirally-wrapping cable including a conductor and an insulation layer. The insulation layer wraps the conductor. The conductor includes an inner core and two alloy wire layers. The inner core is composed of a carbon fiber core wire in the center and copper leads surrounding the carbon fiber core wire. The two alloy wire layers are formed by wrapping the inner core with a plurality of alloy wires in a spiral manner. Materials of the two alloy wire layers are the same and the spiral directions of the two alloy wire layers outside the inner core are the same. The spiral angels of climb of the two alloy wire layers are in a range between 25 degrees and 45 degrees. According to the invention, the carbon fiber copper core alloy wire spiral wrapping cable is high in tensile strength, good in ductility, low in DC resistance, good in electric conductivity, low in line loss and comparatively low in sag.

Description

The wrapped cable of a kind of carbon fiber copper core alloy wire spiral

Technical field

The present invention relates to technical field of electric wires and cables, relate to especially the wrapped cable of a kind of carbon fiber copper core alloy wire spiral.

Background technology

In the prior art, copper core steel strand wire are present domestic cables that generally use, and its twisted wire is galvanized steel wire, and the sag of this common wire is larger, and line loss is large, and galvanized steel wire weight is large, directly causes the rising of needed capital construction facility cost; In the reconstruction of old circuit process, adopt the method for increasing section to realize that the purpose of increase-volume is bound to change height and the span of steel tower, construction cost is multiplied.

Summary of the invention

Problem for prior art exists the present invention proposes the wrapped cable of a kind of carbon fiber copper core alloy wire spiral.

The wrapped cable of a kind of carbon fiber copper core alloy wire spiral, comprise conductor and insulating barrier, insulating barrier is coated on outside the conductor, wherein, conductor comprises inner core and two alloy wire layers, and described inner core is comprised of the carbon fiber heart yearn at center and the copper conductor that is looped around around the carbon fiber heart yearn, and described two alloy wire layers are formed in the coiling of described inner core external spiral by many alloy wires, the material of two alloy wire layers is identical and the hand of spiral outside described inner core is consistent, and its spiral angle of climb is the 25-45 degree.

Preferably, two alloy wire layers are wrapped outside described inner core by many aluminium alloy wires and form, and perhaps, two alloy wire layers are wrapped outside described inner core by many magnesium alloy wires and form, and perhaps, two alloy wire layers are wrapped outside described inner core by many copper alloy wires and form.

Preferably, the spiral angle of climb of two alloy wire layers is the 30-40 degree.

Preferably, be positioned at the alloy wire quantity of alloy wire layer of internal layer less than the alloy wire quantity that is positioned at outer field alloy wire layer.

Based on disclosing of above technical scheme, the tensile strength of the wrapped cable of this carbon fiber copper core alloy wire spiral is high, good percentage elongation, and the D.C. resistance of cable is little, conducts electricity very well, and line loss is little, and sag is less.
