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] Ship hydrophone equipment needs to use waterproof shielded rubber cables. Since they work underwater for a long time, seawater is very corrosive to cables, so the cables are required to have good waterproof performance and insulation performance. At present, there is no dedicated cable for ships on the market. Cables for hydrophone equipment, non-special cables used in this environment have poor waterproof performance and short service life

Abstract

The invention discloses a cable for ship hydrophone equipment and a manufacturing method thereof, which belong to the field of cables, wherein a cable core is formed by intertwisting four insulated wire cores in a star shaped disposition, and the pitch diameter ratio for intertwisting is 8 to 10; each insulated wire core comprises a core wire conductor in the center; each core wire conductor is formed by intertwisting 16 tinned copper wire bundles with a diameter of 0.15mm to 0.20mm and a single wire elongation at break of 15% to 20%, and the pitch diameter ratio for intertwisting is 8 to 11; the peripheries of the core wire conductors are wrapped with insulating layers in an extrusion way, and the thickness of each insulating layer is 0.60 to 0.62mm; the insulating layers of two of the insulated wire cores, which are opposite to each other, are wrapped with shielding layers, and each shielding layer is formed by weaving the tinned copper wires with a single wire diameter of 0.12 to 0.14mm, and the weaving density is 90% to 95%; the shielding layers are externally lapped with insulated tape lapped layers, and a packing layer which makes the cable core round and complete is arranged on the periphery of the cable core; and the periphery of the packing layer is wrapped with an outer sheath in an extrusion way, and the outer sheath is made from chlorosulfonated polyethylene with a thickness of 1.2 to 1.4mm. The cable has advantages of fine insulating property, long service life and capability of meeting the operational requirements of the ship hydrophone equipment.
