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 insulation screen, semiconductive water-blocking buffer layer, copper strips lapping layer, semiconductive water-blocking buffer layer; And said sheath comprises plumbous cover and insulation inner cushion layer, 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 insulation inner cushion layer from the inside to the outside.
Improve, said armouring inner cushion layer is preferably the pitch inner cushion layer of polypropylene rope as inner reinforcement again.
Improve, said armouring external protection can be the pitch outerwrap layer of polypropylene rope as inner reinforcement again.
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 filler can be and gathers third ethene rope again.
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 twisted wire of the strand of steel wire lead wherein aluminum conductor; 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.
