Hotline of power engineering specialists:
Specialists of IDGC of Centre continue the implementation of measures to replace non-insulated wires with self-supporting insulated wire (SIW) on 0.4-10 kV overhead power lines. The work is carried out within the framework of the technical re-equipment and reconstruction program.
Since the beginning of the year, the energy company has replaced 351 km of wire with self-supporting insulated wire. In total, in 2018 the work will cover 919 kilometres of overhead power lines. The largest amount of work will be carried out in the branches of Yarenergo and Orelenergo: 233 km and 158 km of uninsulated wire will be replaced there with SIW, respectively.
Compared to conventional wire, SIW wire has much higher mechanical strength and durability. Its application in 0.4-10 kV grids allows reducing operating costs for line maintenance, decreasing the number of unauthorized connections to grids and cases of wire theft. In addition, the use of SIW wire can reduce the number of interruptions due to sticking and formation of snow and ice. All this in the end contributes to improving the reliability of electricity supply to consumers.
It should also be noted that the use of self-supporting insulated wire reduces the number of cases of electric injuries and improves the overall aesthetic characteristics of electric grids.
