Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 92 words
A steel-cored aluminum cable for electric power conduction, comprising a steel core including a plurality of steel wires, an aluminium coating disposed all around the wires and formed from an aluminium sheet having an inner surface pressed into direct contact therewith and a substantially cylindrical outer surface and a plurality of aluminium staples disposed around the aluminium coating ans upset into direct contact with the cylindrical outer surface of the aluminium coating along the entire innermost circumferential surface of the aluminium staples to impart a trapezoidal cross-section to each of the staples.
Claim 2
Dependent Claim 92 words
A steel-cored aluminum cable for electric power conduction, comprising a steel core including a plurality of steel wires, an aluminium coating disposed all around the wires and formed from an aluminium sheet having an inner surface pressed into direct contact therewith and a substantially cylindrical outer surface and a plurality of aluminium staples disposed around the aluminium coating ans upset into direct contact with the cylindrical outer surface of the aluminium coating along the entire innermost circumferential surface of the aluminium staples to impart a trapezoidal cross-section to each of the staples.
Claim 3
Dependent Claim 21 words
The steel-cored aluminium cable according to claim 1, wherein any space between the steel core and the coating contains anti-corrosive filling.
Claim 4
Dependent Claim 15 words
The steel-cored aluminium cable according to claim 2, wherein the filling is acid free vaseline.
Claim 5
Dependent Claim 25 words
The steel-cored aluminium cable according to claim 1, wherein the coating is formed at least two aluminium sheets engirdling each other on the steel core.
Claim 6
Dependent Claim 63 words
Process for producing the steel-cored aluminium cable according to claim 1, characterized in that beside the seel cable (2) aluminium sheet (8) is deflected, then during their forwarding together, the aluminium sheet (8) is continuously bent around the steel cable (2) and pressed onto the steel cable (2), and thereafter, the aluminium mantle is stranded onto the coating (3) made of aluminium sheet.
Claim 7
Dependent Claim 29 words
Process according to claim 5, characterized in that before the contacting the aluminium sheet (8), an anticorrosive substance, expediently acid-free vaseline (5) is supplied to the steel cable (2).
Claim 8
Dependent Claim 40 words
Process according to claim 5 or 6, characterized in that the steel cable (2), together with the aluminium sheet (8), being led through a drawing stone (9), the aluminium sheet (8) is bent and pressed onto the steel cable (2).
Claim 9
Dependent Claim 27 words
Process according to claim 5 or 6, characterized in that the aluminium sheet (8) is bent and pressed onto the steel cable (2) by means of rolls.
Claim 10
Dependent Claim 51 words
Process according to claim 5, characterized in that during the bending and pressing of the aluminium sheet (8) onto the steel cable (2) a load generating a stress belonging to, or higher than the yield point of the material of the aluminium sheet (8) is exerted onto the aluminium sheet (8).
Claim 11
Dependent Claim 32 words
Process according to claim 5, characterized in that the aluminium mantle is upsetted onto the steel core (2) provided with coating (3) expediently by leading it through a drawing stone (11, 13).
