Problems solved by technology

[0002] EPDM rubber is widely used as wire and cable insulation materials because of its excellent electrical properties, high heat resistance and aging resistance, and good low temperature flexibility. However, the insulation properties of different formulations of EPDM rubber vary greatly.
[0003] Waterproof shielded rubber cables are required for surface ships, submarines or fixed underwater sonar transducers. Since they work underwater for a long time, seawater corrodes the cables severely, so the cables are required to have good waterproof and insulation properties. At present, there is no cable specially used for underwater sonar transducers of ships on the market. Non-special cables used in this environment have poor waterproof performance and short service life.

Abstract

The invention discloses a ship underwater sonar transducer cable of the cable field and a manufacturing method of the cable. A cable core is formed by inter-stranding two shielding insulated cores with a stranding pitch diameter ratio of 10-12. The shielding insulated core includes a core conductor which is arranged in the center of the shielding insulated core. The core conductor is formed by inter-stranding a plurality of tinned copper wire bundles which have a diameter of 0.3 mm-0.35 mm, a single fiber elongation at break of 15%-20%, and a stranding pitch diameter ratio of 8-11. A rubber insulating layer having a thickness of 0.8-0.9 mm is extruded around the core conductor, and the maximum thickness of the same cross section is not larger than 1.25 times the minimum thickness. The rubber insulating layer is peripherally coated with a shielding layer. The cable core is peripherally extruded with an inner sheath and an outer sheath. The cable is good in waterproofness and insulatibity, has a long service lifetime, and is able to work underwater for a long time.
