Abstract

The invention belongs to the field of a cable and particularly relates to an offshore composite cable with low-temperature resistance, salt spray resistance and high strength. The problems that the existing composite cable cannot meet the requirements of low temperature resistance and salt spray resistance can be solved. The composite cable is provided with an insulating cable core, a flame-resistant glass woven belt cushion layer and a flame-resistant polyvinyl chloride elastic body jacket; wherein the insulating cable core is divided into first to fifth layers of insulating cable cores which are arranged from inside to outside; the flame-resistant glass woven belt cushion layer is coated outside the fifth layer of the insulating cable core; and the flame-resistant polyvinyl chloride elastic body jacket is arranged outside the flame-resistant glass woven belt cushion layer. The offshore composite cable with low-temperature resistance, salt spray resistance and high strength is high in strength and has good performances of low temperature resistance and salt spray resistance in seawater, and the like.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a low-temperature-resistant, salt-spray-resistant, high-strength integrated marine cable. Background technique [0002] In the field of photoelectric transmission, cable is a very important transmission medium, and has been widely used in the field of signal transmission technology. [0003] Existing integrated cables can transmit electrical signals and power at the same time, but they only simply twist together the signal transmission unit for transmitting electrical signals and the power supply unit for transmitting power. Such a structure is too simple, making the complex complex The cable cannot withstand external force and is easily deformed, which cannot meet the requirements for comprehensive cable resistance performance. [0004] In addition, because the signal transmission unit and the power supply unit in the existing integrated cable are simply wrapped in the sheath, and the sig...
