Abstract
Использование: в воздушных лини х электропередачи. Сущность изобретени : с целью повышени эксплуатационной надежности провода путем снижени его веса стальной сердечник заменен на алюминиевый с проволоками, диаметр которых в три раза меньше, чем у стальных. 2 ил.Usage: in overhead power lines. SUMMARY OF THE INVENTION: In order to increase the operational reliability of a wire by reducing its weight, the steel core is replaced by an aluminum core with wires whose diameter is three times smaller than that of steel. 2 ill.
Description
Изобретение относитс к кабельной технике, в частности к конструированию неизолированных проводов дл воздушных линий электропередачи.The invention relates to cable technology, in particular to the design of bare wires for overhead power lines.
Целью изобретени вл етс повышение надежности провода путем уменьшени его веса,The aim of the invention is to increase the reliability of the wire by reducing its weight,
Сущность изобретени по сн етс чертежом , на котором показаны поперечные сечени двух конструкций провода (фиг. 1 и 2).The invention is illustrated in the drawing, which shows cross-sections of two wire structures (Figs. 1 and 2).
Сердечник провода выполнен из алюминиевых проволок, при этом диаметр проволок 1 в сердечнике по крайней мере в 3 раза меньше диаметра проволок 2 в пови- вах. Разрывна прочность такого проводаThe core of the wire is made of aluminum wires, while the diameter of the wires 1 in the core is at least 3 times smaller than the diameter of the wires 2 in the grades. Breaking strength of such a wire
не уступает разрывной прочности провода- прототипа, имеющего стальной сердечник. Уменьшение же веса от замены стального сердечника на алюминиевый повышает эксплуатационную надежность провода, уменьша усили в зажимах.not inferior to the breaking strength of the prototype wire having a steel core. Reducing the weight from replacing the steel core with aluminum increases the operational reliability of the wire, reducing the force in the clamps.
