Abstract:

An all-plastic submarine cable capable of carrying simultaneously audio and carrier frequencies, named Quina, is described. The cable core comprises five conductors, namely a polyethylene insulated central copper wire and four curved copper strips, suitably spaced and spirally applied upon the said central insulated conductor on the four copper strips a polyethylene jacket and finally a copper screening tape are applied. The four small tapes can be used as a symmetrical star quad for audio or low carrier frequencies, and the coaxial pair having the four tapes as outer conductor and the central wire as inner conductor for frequencies above say 60 kcsec the two systems being used simultaneously if desired. The cable armour can be of the conventional type or of the antitwist type comprising parallel strands embedded in a polyethylene sheath. Author
