Hotline of power engineering specialists:
Specialists of Rosseti Centre and Rosseti Centre and Volga Region* continue to implement measures to replace non-insulated wires for self-supporting insulated wires (SIW) on 0.4-10 kV overhead power lines. Work is being carried out as part of a technical re-equipment and reconstruction program.
In the first half of the year, the power engineers replaced 735 kilometres of wire with SIW, which is more than 100% of the plan. 1.358 billion rubles were allocated for these purposes. In total, in 2019 the work will cover 1,814 kilometres of overhead power lines. The largest volume of work will be carried out in the branches of Tverenergo, Yarenergo, Belgorodenergo, Ryazanenergo, Kirovenergo, Kalugaenergo. The total funding will amount to 4.166 billion rubles.
Compared with ordinary wire, the SIW wire has much higher mechanical strength and durability. Its use in 0.4-10 kV grids allows reducing operating costs for line maintenance, decreasing the number of unauthorized connections to grids and cases of theft of wire. In addition, the use of self-supporting insulated wire allows reducing the number of breaks due to sticking and freezing of snow and ice. All this ultimately helps increase the reliability of power supply to consumers.
In addition, the use of self-supporting insulated wire reduces the number of cases of electrical injuries and improves the overall aesthetic characteristics of electric grids.
