The article proposes the use of air signal systems (IVS) on Mi-8 and Mi-24 helicopters in order to improve the reliability of airmetric power systems.

Successful long-term experience (since 1982) in field testing of linear polymer insulators on existing Yakutskenergo power transmission lines (35 kV and 110 kV)shows advantages over traditional insulators made of glass and porcelain in the extreme climate of the North. The estimated durability of polymer insulators is approximately 40 years. Further field tests of suspended polymer insulators would be valuable in determining the durability and reliability of electrical and mechanical parameters of polymer insulators and would allow them to be recommended as highly reliable products for industrial energy in the North.
