The invention discloses a low-loss stable-phase cable. The cable comprises a silver-plated soft round
copper wire inner conductor, a microporous
polytetrafluoroethylene tape insulator, a silver-platedcopper flat tape outer conductor, a silver-plated soft round
copper wire outer conductor and a
fluorinated ethylene propylene sheath, wherein the outer side of the silver-plated soft round
copper wire inner conductor is wrapped with the microporous
polytetrafluoroethylene tape insulator, the outer side of the microporous
polytetrafluoroethylene tape insulator is wrapped with the silver-plated copper flat tape outer conductor, the outer side of the silver-plated copper flat tape outer conductor is wrapped with the silver-plated soft round
copper wire outer conductor, and the soft round copperwire drawing is realized through the
size difference between the two
wire drawing wheels;
wire drawing is convenient, the efficiency is high,
wire drawing is carried out in water, so that the phenomenon that a
copper wire is easy to deform and break during traditional wire drawing is avoided, the
copper wire is ensured to be in a low-temperature environment through
underwater wire drawing, deformation of the copper wire due to local heating is avoided, the soft round copper wire is ensured to be tightly wound on the collecting roller through supporting and tightening of the first guide wheel and the second guide wheel, and the elastic retraction phenomenon of the soft round copper wire is avoided.
