Abstract
The utility model provides an intensity aluminium alloy stranded conductor in steel core, it includes the enhancement core that comprises at least one galvanized steel wire and spiral winding intensity aluminiumalloy wire in strengthening the at least one deck of core outlying, the intensity aluminiumalloy wire includes many single lines in every layer, every adjacent in two -layer spiral winding opposite direction of intensity aluminiumalloy wire. The utility model discloses intensity aluminium alloy stranded conductor in steel core has guaranteed the power of breaking of wire owing to adopted zinc -plated steel core as strengthening the core, adopts the conductivity be among the 57 percentIACS intensity aluminiumalloy wire as the current -carrying part, not only increases the tensile strength of whole wire, also makes the resistance reduction of whole wire, and the transport capacity is higher, has reduced the line loss, is particularly useful for well ice formation.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to strength aluminium alloy twisted wire in a kind of steel core.
Background technology
Cable is widely used in transmission line, especially aerial high-voltage power transmission line.For the cable for ice formation aerial high-voltage power transmission line, not only require that it has higher tensile strength, also require lower conductor resistance, meet circuit conveying and require to reduce line loss simultaneously.Be used for now the ACSR with high strength aluminium wires of ice formation, wire transmission capacity is limited, and line loss is larger.
Utility model content
The purpose of this utility model, has strength aluminium alloy twisted wire in the steel core of good tensile strength to provide a kind of exactly.
In order to achieve the above object, the utility model have employed following technical scheme: strength aluminium alloy twisted wire in a kind of steel core, comprise strength aluminium alloy line in the strengthening core be made up of at least one galvanized steel wire and at least one deck being spirally wound on strengthening core periphery, in every layer, strength aluminium alloy line comprises many single lines, and in every adjacent two layers, the spiral winding direction of strength aluminium alloy line is contrary.
The middle strength aluminium alloy line of described middle strength aluminium alloy line to be conductance be 57%IACS.
Described strengthening core is made up of a galvanized steel core and the six roots of sensation galvanized steel wire be spirally wound on outside galvanized steel core.
The described middle strength aluminium alloy line being spirally wound on strengthening core periphery is three layers.
The described middle strength aluminium alloy line being spirally wound on strengthening core periphery is four layers.
The described middle strength aluminium alloy line being spirally wound on strengthening core periphery is five layers.
The described middle strength aluminium alloy line being spirally wound on strengthening core periphery is two-layer.
In the utility model steel core, strength aluminium alloy twisted wire is owing to have employed zinc-plated steel core as strengthening core, ensure that the pull-off force of wire, adopt conductance be in 57%IACS strength aluminium alloy line as current-carrying part, not only increase the tensile strength of whole wire, also the resistance of integrated wire is made to reduce, transmission capacity is higher, reduces line loss, is particularly useful for middle ice formation.
