OPTIMAL LOCATION OF COMMUNICATION LINES AND POWER LINES ON COMMON SUPPORT

Abstract

In the energy sector of Russia, there is a growing demand for electricity. An advantageous way to provide communication and power services is the construction of overhead lines and power lines. There is a connection of new consumers to existing lines. At the intersection of communication lines and power lines, a “tangle” of wires is formed, making it difficult to carry out installation
and repair work. When carrying out any work related to the installation, repair or maintenance of supports with such “tangles”, the risk of electric shock and the risk of workers falling from a height increase significantly. To reduce the complexity of maintenance and increase safety at key intersections, a constructive solution has been proposed in the form of a traverse. The proposed traverse will allow to arrange the placement of wires of communication lines and power lines at the nodes of their intersection, that is, it will allow optimization of the mutual placement of wires in space. Optimization of the mutual placement of wires in space meets the conditions for increasing the safety of work on supports and the convenience of servicing communication lines and power lines. In addition, the placement of wires using the proposed crosshead significantly improves the appearance of the supports themselves and the surrounding areas, since no “tangles” of wires are formed. To justify the feasibility of introducing the developed design,
an assessment was carried out of the professional risk of injury to electricians performing maintenance work on power lines, using and without a prototype traverse. The trial operation of the traverse was carried out at 17 work sites, each of which employed 15 electricians. The experiment showed that when using a traverse, the likelihood of safe work at work sites increased. Thus, the calculations showed that the proposed design can improve the safety of electricians
