FIELD: electricity. ^ SUBSTANCE: high-voltage overhead line includes tower supports mounted on foundations with traverses, isolators, dead-end and suspended clamps with multi-core electric lines attached in them, including, at least, one of multi-core electric lines contains a core with not less than one composite core and multi-core lay. Note that high-voltage overhead line is erected and adapted for performing necessary repair works in the course of operation with removal of damaged or overage electric lines and their replacement by substituting high-temperature composite multi-core electric lines laid by repair method that provides technological and operational undamageability of the said substituting lines. ^ EFFECT: there performed is a mounting of substituting electric line with reeling out through braking machine with simultaneous provision of technological tension of electric line by tensioning machine, use of pay-out rollers adapted to electric lines substituting during repair and performed for this purpose with undamaging channel, as well as precise regulation of minimum allowable diameters of drums with individual factory winding of electric wires and drums of braking machine performed complying the condition of undamageability of the said highly efficient and economical material by consumption as well as by reduced resistance per unit of electric lines transported energy. ^ 15 cl, 8 dwg |
