Embodiment Construction

[0024] The insulating thickness of the extruded and irradiated cross-linked ethylene-propylene rubber insulating layer 2 is 0.8-1.4 mm. The extruded radiation cross-linked neoprene inner sheath 5 has a thickness of 1.3-1.5 mm. The extruded radiation crosslinked neoprene outer sheath 7 has a thickness of 2.0-3.5 mm.

[0025] The manufacturing process of the above-mentioned deep-water sealed rubber-sheathed cable is as follows:

[0026] Step 1: Use 7 strands of annealed copper wire, and perform normal stranding according to the arrangement of "1+6" to obtain a conductor. Gap between copper wires;

[0027] Step 2: Dry the irradiated ethylene-propylene rubber material at 50±5°C for 2 hours and inject it into a plastic single-screw extruder to complete the extrusion of the irradiated cross-linked ethylene-propylene rubber insulation layer to obtain an insulated wire core; Extrusion molds are used in the plastic single-screw extruder described above. The temperature of the feed i...

Abstract

The invention discloses a deep water seal rubber sleeve cable and a manufacturing process thereof. A cable conductor is formed by twisting seven annealed copper wires and is coated with sealing glue. Insulation is achieved through irradiation crosslinking ethylene propylene rubber. Gaps among core wires are filled with water blocking glue when the core wires are twisted to form a cable core of a cable body. A water blocking wrapping band wraps the cable body. An irradiation crosslinking chloroprene rubber inner protective sleeve is arranged on the cable body in an extruding mode. A protective sleeve reinforcing layer is woven from tin-plated annealed copper wires coated with sealing glue. Finally, an irradiation crosslinking chloroprene rubber protective sleeve is arranged on the cable body in an extruding mode. The cable is reliable in longitudinal water-tightness performance, high in flexibility and resistant to seawater corrosion and deep water pressure; reliability of power transmission and control signal transmission can be normally kept under a certain water pressure condition. The cable can be used for cable transmission and control signal transmission of electrical instruments and power distribution units of underwater crafts, marine business, underwater equipment and marine survey systems and underwater mining devices.

Description

technical field [0001] The patent of the invention relates to a deep-water sealed rubber-sheathed cable and its manufacturing process, belonging to the technical field of electric wires and cables. Deep water sealed rubber sheathed cables are mainly used in signal transmission, control and measurement systems of electrical instruments and power distribution devices of underwater ships. Background technique [0002] With the continuous development of science and technology, watertight series cables are indispensable components for information transmission in the field of underwater and marine technology. Watertight cables are mainly used in the signal transmission, control and measurement systems of electrical instruments and power distribution devices of underwater ships. They are key components connecting the power and control systems in ships. The reliability of signal transmission must also ensure the safety of the underwater ship or device of the watertight cable under ...
