ENVIRONMENTAL IMPACT OF SEMIINSULATED CONDUCTORS
KOMUNALNA ENERGETIKA / POWER ENGINERING, 18
For overhead power lines, there are increasingly used compact conductors with carbon core. If such a conductor is »incomplete« isolated, we get covered conductorm which is mechanically stronger and what is even more important, it is spatially less wasteful. Furthermore, because of the isolation the electric field strength is lower near such a conductor.
There is a design of a covered conductor given in this article, which we could install on the existing 220 kV columns and so increase the transmission capacity of the Slovenian electricity network. The integration of regular energy infrastructure is increasingly demanding, therefore we investigated the impact of such covered conductor for the highest voltage levels to the environment. We compared the analytical calculation of the electric field strength near the proposed covered conductor with the method of finite elements. The results were evaluated according to the regulation on electrictromagnetic radiation in the natural and living environment.
