  • Publication number: 20190259507
    Abstract: A conductor for a power transmission cable including at least two separate lengths of conductors, having at least 99.5% by weight aluminium, and the remainder other metals or substances except a titanium content of at most 0.02% by weight. The at least two lengths of aluminium conductors joined together by a weld. The welding material alloy has an aluminium content of at least 85.2% by weight, a silicon content of from 4.0 to 13.0% by weight and the remainder up to 100% by weight and at most 1.8% by weight, other metals and/or substances; or an aluminium content of at least 99.5% by weight, a titanium content of from 0.10 to 0.50% by weight and the remainder up to 100% by weight, other metals and/or substances.

  • Patent number: 10224704
    Abstract: A welding sleeve for armored cables including a first sleeve part arranged to receive an armored cable, wherein the first sleeve part has a perimeter surface for welding armoring wires of an armored cable thereto, a second sleeve part arranged to receive an armored cable, wherein the second sleeve part has a perimeter surface for welding armoring wires of an armored cable thereto, wherein the first sleeve part is arranged to receive the second sleeve part, the second sleeve part being axially displaceable relative to the first sleeve part, along a common central axis, between an extended position and a retracted position, in which retracted position the first sleeve part receives a greater portion of the second sleeve part than in the extended position, and a rotation preventing arrangement arranged to prevent rotational motion of the first sleeve part relative to the second sleeve part.
