FIELD: electric power engineering.
SUBSTANCE: invention relates to electric power industry, namely to tension pressing clamps for attachment to supports of overhead transmission lines of antivibration steel and aluminum wires twisted from two conductors. Clamp consists of housings 3, 4, connected with housings 3, 4 of anchors 5, 6 and lugs 7, 8. Clamp structure includes link 9 intended for connection with elements of insulating suspension of overhead transmission line. In hole 10 of link 9 there are anchors 5, 6 of housings 3, 4 hingedly fixed. Breaking load PBR.LIN of link 9 is determined depending on rupture force of twisted wire PRUP.TW.W from the ratio: PBR.LIN≥1.125·PRUP.TW.W·0.6.
EFFECT: proposed tension pressing clamp is simple in terms of design and manufacturing technology, reliable in continuous operation.
