Calculation of Admissible Currents for the Protected Wires of 110 kV Overhead Lines

详细

Protected wires have insulation from cross-linked polyethylene with low heat conductivity, which impairs heat removal from the hot wire. A methodology is proposed for designing admissible continuous currents for the insulated wires of overhead transmission lines, taking into account various climatic conditions, and based on the solution of the equation of thermal balance. The materials provided in this article can be used for design and operation of overhead transmission lines on which the protected wires are used.
