The utility model relates to a wire fixed knot constructs, especially relates to a 10kV overhead line wire fixed knot constructs. It includes aluminium package steel wire, and it makes the preformed helical wiring by two aluminium package steel wires at least, and this preformed helical wiring is fixed the wire and is formed U -shaped elbow section, pin insulator neck groove department's circular arc section and the leg wrappings wire section of holding with a firm grip, the U -shaped elbow section of the fixed wire of preformed helical wiring department compress tightly fifty percent discount behind the wire, fifty percent discount once more behind the opposite side is twined in the neck groove of prolonging pin insulator, twists reverse the preformed helical wiring of fifty percent discount, last turn round that tight preformed helical wiring is the leg wrappings wire section of holding with a firm grip and form the tubulose spiral and extend the form. The utility model discloses has solved not only that the long -time operation of traditional wiring is ageing to lead to the deterioration of strength problem, has still avoided because of construction technical problem leads to ligature technology not pass a test, meet extremely rugged environment still can normal operating, the grip is never released, reduces heavily to pollute regional distribution lines trouble and take place, has improved electric wire netting safe operation coefficient effectively.
