Researches torsional rigidity of wires for electricity transmission air-lines
Abstract: In article the questions concerning researches of torsional rigidity of wires of air-lines of electricity transmission (ET) in laboratory of tests of building strictures and constructions of DonNACEA are considered. To achieve the purpose of researches new types of wires applied in world practice for ET are studied, the stand for rigidity studying on torsion of wires is developed and designed; experimental researches and their analysis are made. It is confirmed that rigidity on torsion of the sector condensed and compact wires (AAAC) above torsion rigidity of traditional steel alluminium wires (ACSR) even under condition of comparison on close values of diameter of a wire. Under condition of comparison of wires on equal current loading, given priority of modern types of wires considerably increases. Results of work are necessary for the further researches concerning studying of influence of wires twisting on icing, and working out the actions for the purpose of maintenance of trouble-free operation of ET at icing-wind influences.
