Power engineering currently seeks, among other things, to use innovative energy-efficient technology and to benefit from the R&D potential associated with grids. Conventional solutions based on general design methodologies are a hindrance in this respect, as they prevent the strategic objectives from having the expected quantitative and qualitative effects in full. Requirements to the reliability, cost-effectiveness, and performance of grid facilities are ever stricter, specifically those to overhead power lines (OPL). Next-gen power lines are proposed as a solution. What makes a power line design next-gen? An innovative wire of cost-effective crosssection, a special tower design, state-of-the-art insulation and ground wire, if necessary. The paper seeks to investigate how innovative OPL components affect the design outcomes from the standpoint of common guidelines and standards. The research uses a systematic approach and presents the specifics of innovative next-gen OPL components to show that standards are sometimes obsolete and do not match the today's state-of-the-art solutions. The paper advocates the development of newer standards and guidelines on OPL design.

Currently, there is an increase in power flows along power lines. An important task for the development of the power grid complex is to increase the current-carrying capacity of existing power lines. The use of advanced conductors has become a successful technical solution for this purpose. "New generation conductors" are modern conductors that have advanced mechanical and electrical properties and characteristics. Thus, it has become important to have information about the maximum operation temperature and current limits of the overhead line with new conductors. The approximate current-carrying capacity in Amperes is the value of current at which the conductor temperature reaches its maximum permissible value. It determines the maximum current load of overhead power lines. For traditional steelaluminum conductors, there are several methodological approaches to determining the maximum current load. This fact complicates the definition of an approach to calculating the current carrying capacity for advanced conductors. Nevertheless, the general basis of all methodological approaches is the thermal balance of the conductor. The purpose of this article is to assess the possibility of adapting the method of calculating the approximate currentcarrying capacity of traditional conductors to the calculation of advanced conductors. The article deals with advanced conductors of various brands of comparable cross-section with the classic ACSR 240/39. This work provides information about the selected conductors, their characteristics and design features. The paper shows a mathematical model for calculating the approximate current-carrying capacity of a conductor and shows calculating results for selected conductors. According to the results of analysis and calculations, the adaptation of the presented mathematical model is possible if we refine its parameters and coefficients.
