Mixed type glass suspension string unit will improve the reliability of networks of IDGC of Urals

The pollution of the insulation of overhead transmission lines are one of the causes of technological violations in grid complex. According to experts, outages on distribution networks up to 110 kV connected with reasons which are difficult to diagnose: dew, air ionization, and icing. Mixed type glass suspension string units with different diameters and other innovative solutions will allow minimizing outages and reducing energy costs.

Today mixed type glass suspension string units are designed and manufactured in Yuzhnouralsky Insulators and Fittings Plant (part of the holding Global Insulator Group).

Mixed type glass suspension string units (insulators of antifog and aerodynamic profiles) are able to self-cleaning from dry dust deposits. At the blowing of wind flow with fine disperse particles of mud the flat plate of aerodynamic insulator does not create eddy currents in both upper and lower surfaces, and the particles of mud does not precipitate. The difference between the diameters of the insulators reduces the possibility of overlapping due to overvoltage in the conditions of rain.

This technical solution and other innovations will now be used in the networks of OJSC "IDGC of Urals" (enters into Group of companies PJSC "Rosseti"): on 12 July in Yekaterinburg was signed the agreement on joint technical cooperation between "IDGC of Urals" and "YuAIZ". According to the document, "YuAIZ" will participate in the pilot projects of "IDGC of Urals", which directed to ensure the reliability of work of the electric grid complex. Together with specialists in energy the industrial enterprise will create patentable technological solutions in the field of line insulation. "YuAIZ" will also participate in expert evaluation during emergency situations in electricity distribution networks. The agreement was signed within the international forum "INNOPROM 2016".

According to the words of President of "Global Insulator Group" Dennis Tasakov, the signed agreement directed to the application on the lines already developed in JSC "YuAIZ" new types of insulators and insulating suspension and in joint work to determine the causes of outages that affect the insulation of the lines. «It is here the same interests of "IDGC of Urals", as a network company and "YuAIZ", which produces insulation for power lines. Therefore, this agreement is so important for both companies ", — commented Denis Tasakov.

"The agreement on technical cooperation — another example of the close cooperation of the industrial enterprises and the specialists of the electric grid complex, which directed to improve the technical characteristics of the equipment operation, as well as to demonstrate that the industry is ready to support and contribute to the introduction of advanced domestic innovations," — said General Director of JSC "IDGC of Urals" Sergey Dregval.
