Design procedures for high-voltage direct current transmission cables

摘要

The design of HVDC cables is governed by maximum acceptable values of conductor and ambient temperatures, and by maximum acceptable values of transient and steady-state stresses (voltage gradients) in the cable dielectric. Because these stress distributions are related in a complex fashion to temperature and stress, iterative procedures are required to design these cables. A logic diagram and all equations and reference required to accomplish these designs are provided. The equations are readily solvable with a calculator.
