Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0022] see figure 1 , a LAN cable for ships, including a tape 3 wrapping a core wire 1, a tinned copper wire armor layer 4 is braided outside the tape 3, and a low-smoke and no-smoke layer is formed outside the tinned copper wire armor layer 4. Halogen flame retardant polyolefin jacket5. The diameter of the direct grounding copper wire 2 is Φ0.50mm.

[0023] The core wire 1 includes a wire pair 11, a wrapping tape 12 wrapped outside the wire pair 11, an aluminum foil longitudinal wrap 13 wrapped outside the wrapping tape 12 and the direct grounding copper wire 2, and a low-smoke, halogen-free flame retardant molded outside the aluminum foil longitudinal wrap 13. Polyolefin sheath14. The diameter of the direct grounding copper wire 2 is Φ0.5...

Abstract

This invention discloses a LAN cable armored technology used in ships including the following steps: 1, forming a core wire with a belting wrapping a line pair then wrapping the core wire with longitudinal Al foil and directly putting earth copper wire to put them into an extruder to be extruded to form a molding low smoke halogen-free flame retarding polyolefin jacket, 2, armoring the jacket on a high speed weaving machine, 3, the armored cable enters into the extruder to be extruded to form a low smoke halogen-free flame retarding polyolefin jacket. This invention adds a tinned copper wire armored layer with 30% weaving density outside of a core to double-screen together with longitudinal-wrapped Al foil, in which, the screen density reaches to 100%.

Description

technical field [0001] The invention relates to a preparation method of a local area network cable for network communication, in particular to an armoring process of a local area network cable for ships. Background technique [0002] On a ship, cables are like human blood vessels and nerves all over the ship's body, responsible for power supply, signal control and communication, to ensure the normal operation of the ship. With the improvement of the degree of automation of modern ships, various network systems are used more and more on ships, and the number and requirements of the required LAN are getting higher and higher. Since ships are often in a complex electromagnetic environment, general communication cables are generally not suitable for ships due to their large attenuation of digital signal transmission and unstable transmission quality. [0003] At present, the LAN cables used on ships are all imported land-use shielded Category 5 network cables. Although the lan...
