Abstract :
A new computer model is presented for precise calculation of sag and tensions of composite conductors for overhead lines. All the effects known to increase the sag are accounted for: residual deformations, evolution of creep with time, compression in aluminum layer of ACSR conductors at high temperature, etc. This general model can also be applied for the simpler cases of one-material conductors and messengers supporting multiples or telecommunication cables
