Abstract
Due to advantages of increase of safety and reduction of short circuit, overhead transmission lines with covered conductors have spread gradually. Analytical expressions of electric field to overhead transmission lines with covered conductors are presented. Calculation methods of allowable current and temperature to covered conductors are presented. Calculations of electric field and temperature of overhead lines with bare and covered conductors are taken. Results show differences of electric field and temperature to overhead lines with bare conductors and covered conductors.
