Low-smoke halogen-free flame-retardant oil-resistant data transmission bus cable for ship and ocean engineering equipment and manufacturing method thereof

Abstract

The invention discloses a low-smoke halogen-free flame-retardant oil-resistant data transmission bus cable for ship and ocean engineering equipment and a manufacturing method thereof. The data transmission bus cable comprises stranded copper wire conductors, light skin-foam-skin structure physical foaming polyethylene insulation layers, tension-resist customized-size filling strips, a single-sided aluminum-plastic film composite shielding warping tape, a flexible multi-strand tinned copper wire braided shielding net, a high-flame-retardant low-smoke halogen-free polyolefin oxygen barrier layer and a high-oil-resistant low-smoke halogen-free flame-retardant crosslinked polyolefin sheath. According to the bus cable, by combining ship cable laying and use environment, the tension-resist filling elements are added between cable cores; through a skin-foam-skin physical foaming structure, data transmission stability is improved; and by increasing the environment-friendly oxygen barrier layer and the sheath layer having excellent physical and chemical properties, safety, reliability and environment adaptability of the cable are improved to be maximum degree, so that the cable is allowed to be fully suitable for ship and ocean engineering application environment, and the cable is allowed to have low-smoke halogen-free flame-retardant and oil-resistant properties and high mechanical protection capability and the like.

Description

technical field [0001] The invention relates to a cable, in particular to a low-smoke, halogen-free, flame-retardant and oil-resistant data transmission bus cable suitable for use in ships and marine engineering equipment environments and a manufacturing process thereof. Background technique [0002] Data transmission bus cables play a dominant role in various automation fields, and the number of device nodes in the world has exceeded 20 million. It consists of three compatible parts, namely PROFIBUS-DP (Decentralized Periphery), PROFIBUS-PA (Process Automation), and PROFIBUS-FMS (Fieldbus Message Specification). Among them, PROFIBUS-DP is used at the field level. It is a high-speed and low-cost communication used for communication between equipment-level control systems and distributed I / O. The bus cycle is generally less than 10ms, using the first and second layers of the protocol and the user interface to ensure fast and efficient data transfer. ; PROFIBUS-PA is suitabl...

AI Technical Summary

Problems solved by technology

[0003] As an independent application system, shipbuilding and marine engineering, with the wide application of more and more automation equipment in its system, the corresponding data transmission bus cables have also shown a considerable demand. However, due to The particularity of the application environment system of ships and ocean engineering equipment has high requirements on the safety, reliability, and environmental adaptability of cables. Relatively speaking, ordinary data transmission bus cables and their manufacturing processes suitable for land application environments The extent to which these requirements are met is not satisfactory
