As improvement, said steel reinforced aluminium conductor structure is meant: some strands of steel wire leads are positioned at the center, and some strands of aluminum conductors are outside the steel wire lead and be twisted into the steel reinforced aluminium conductor conductor each other.
As improvement, said screen comprises semi-conductor electricity band and conductor shield, and core is wrapped in the semi-conductor electricity band, and the semi-conductor electricity band is wrapped in the conductor shield.
Improve again; Said insulator screen comprises that insulation screen, semiconductive water-blocking buffer layer, copper strips lapping layer, semiconductive water-blocking buffer layer are the insulator screen; And said sheath comprises plumbous cover and semiconductive polyethylene inner cushion layer, and it arranges routine position for being followed successively by insulation screen, semiconductive water-blocking buffer layer, copper strips lapping layer, semiconductive water-blocking buffer layer, plumbous cover and semiconductive polyethylene inner cushion layer from the inside to the outside.
Improve, said armouring inner cushion layer may be selected to be the pitch inner cushion layer of polypropylene rope as inner reinforcement again; And said armouring external protection is the pitch outerwrap layer of polypropylene rope as inner reinforcement.
Improve, said armour is made up of many galvanized steel wire ropes again, and said galvanized steel wire rope is positioned at the structure of same periphery distribution with cross section and the protective layer that forms.
Improve, said armour is being provided with between galvanized steel wire rope at a distance from the magnetic aluminum-alloy wire again, and said galvanized steel wire rope is positioned on the same periphery with the cross section of separated magnetic aluminum-alloy wire.
As further improvement; Also be provided with the optical cable layer between said armour and the armouring inner cushion layer; This optical cable layer comprises cable line, polyethylene interstitial wire and supports aluminium alloy wire; The cross section of said cable line, polyethylene interstitial wire and support aluminium alloy wire is positioned on the same periphery; And the left side of per two cable lines is arranged in order and is the polyethylene interstitial wire, supports aluminium alloy wire, and it is the polyethylene interstitial wire that the right of these two cable lines is arranged in order, support aluminium alloy wire, and per two cable lines and about each two polyethylene interstitial wire, support the six roots of sensation line that aluminium alloy wire forms and consist of repetitive and rearrange the optical cable layer.
Compared with prior art, the present invention adopts core to be made up of steel wire lead and aluminum conductor, and said steel wire lead is positioned at the center of core, and steel wire lead and aluminum conductor are twisted into the formed core of steel reinforced aluminium conductor structure jointly.The advantage of this structure is; Replaced copper by aluminium, not only provided cost savings, and the also complete conformance with standard of conductivity; And the blend of the strand of steel wire wherein aluminium; Can exempt to mend the not enough problem of aluminum conductor tensile strength again, so the cable that the present invention processes had both reduced production cost, and conductivity and tensile strength standard all up to specification.
