MES Urals to introduce the latest technology to strengthen the foundations of supports 220-500 kV transmission lines using high-carbon fiber. The work carried out in preparation for the power grid facilities of JSC "FGC UES" to the period of the heating season 2012-2013.
Carbon fiber reinforcement fully recovers bearing capacity of the structure, blocking the process of destruction of the support. The foundation supports subjected to a special anti-corrosion treatment, followed by polymer-formulations restored geometry of the foundation is applied hydroprotective mastic, on top of which is laid carbon fiber. The polymer material has high seismic resistance and resistance to chemicals, physical and technical characteristics — for example, breaking carbon fiber stronger than metal. In addition, the ease of use of carbon fiber provides the shortest time repairs and reduces their cost.
The new method developed Yekaterinburg Research Institute of high-gain systems OOO "Institute APU" INTER / Energy ‘. "
Currently, work on strengthening the foundation of poles held at 500 kV Tagil — BAZ Reftinskaya — Tyumen 1.2, South — Shagol, Votkinskaya GES — Emelino, Emelino — South, as well as the 220 kV transmission line Serov GRES — BAZ and Sos’va — Krasnotur’insk. By the end of October 2012 with the help of this method will be strengthened foundation supports 18 220-550 kV power lines in Perm, Sverdlovsk and Kurgan regions.
