Abstract

The utility model relates to a network digital cable used for a ship, and belongs to the technical field of the cable. The network digital cable is characterized in that the network digital cable is provided with a cable core composed of quad pair lines, lapped high flame resistant polyvinyl chloride PVC inner sheaths arranged on the wire core, a braided tinned copper wire main shielding layer, a zinc coated steel wire armoring layer, and an extruded low-smoke and halogen-free irradiating crosslinked polyethylene outer protective layer, wherein the tinned copper wire main shielding layer is arranged between the two layers of high flame resistant polyvinyl chloride PVC inner sheaths, and the low smoke and halogen-free irradiating cross-linked polyethylene outer sheath is extruded on the outer surface of the tinned steel wire armoring layer. The network digital cable has the advantages of compact structure and small volume. The product adopts four pair of 8-core ultra five categories of cabled cores, and has the comprehensive performances of flame retardancy, anti-jamming, anti-collision, moisture prevention, salt mist resistance, mildew-resistance, and weather-resistance, has high speed of data transmission, and is accurate and stable and reliable. The network digital cable is an ideal network digital cable, is especially suitable for the computer network used for a modern ship or vessel, and can be taken as a signal transmission line.

Description

Network data cable peculiar to vessel

Technical field

The utility model relates to a kind of structure of cable, particularly is adapted to the supporting structure with cable of boats and ships network, belongs to the cable technology field.

Background technology

Continuous progress along with science and technology, the application of computer in boats and ships is also more and more widely with universal, it is not only provided convenience for the routine office work of boats and ships, and to the safety in production of boats and ships, the raising of operating efficiency, the standardization of ship operation provides necessary condition.In recent years, along with development of internet technology, the particularly injection of local area network (LAN), local area network (LAN) rises thereupon, installs and uses in the boats and ships, for the transmission of the sharing of information resource of boats and ships and data, pass to move convenience be provided, also opened up new thinking simultaneously, in whole network for the management of boats and ships, netting twine is one of them most important component, has played a core tie that information is transmitted.Because influenced by external environment and ocean climate bigger for hull, especially under the mal-conditions such as rolling in broad water environment, trim and temperature, salt fog, humidity, radiation, narrow space in the boats and ships in addition, various kinds of equipment is intensive, and the phase mutual interference is very serious.In view of the foregoing develop a kind of network data cable peculiar to vessel, it is supporting to satisfy the modern ships network, is a urgent task of cable research and production enterprise.

The utility model content

The purpose of this utility model is for satisfying the needs of the modern ships network market, a kind of network data cable peculiar to vessel being provided.

The purpose of this utility model is to realize like this, network data cable peculiar to vessel, the low smoke and zero halogen IXPE outer jacket that it is characterized in that being provided with total screen of tinned copper wire that wrapped high flame retardant polyvinyl chloride PVC inner sheath, braiding are set on cable core that four phase-splittings, eight heart yearns constitute and the cable core and zinc-coated wire armour and extrude, the total screen of tinned copper wire is arranged between the two-layer high flame retardant polyvinyl chloride PVC inner sheath, and low smoke and zero halogen IXPE outer jacket is extruded in zinc-coated wire armour outer surface.

Described phase-splitting is extruded by zinc-plated copper free wire outer surface that wrapped aluminium-plastic tape phase-splitting screen constitutes on the line group of insulated wire cores pair twist of high density polyethylene (HDPE) PE insulating barrier.

The utility model compactness rational in infrastructure, volume is little.Product adopts 4 pairs 8 core CAT5E UTP cable to become cable core, wrapped phase-splitting screen of aluminium-plastic tape and tinned copper wire are set weave total screen, adopt double-deck inner sheath to add armour and oversheath, have fire-retardant anti-interference, anti-collision, the transfer of data of damp proof, anti-salt fog, mould proof, weather and two-forty and combination property such as accurately reliable and stable.Be a kind of desirable network data cable, be specially adapted to the peculiar to vessel and warship of modernization and use, make signal transmssion line with computer network.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure: 1 zinc-plated copper free wire, 2 insulating barriers, 3 phase-splitting screens, 4 inner sheaths, 5 total screens, 6 inner sheaths, 7 armours, 8 outer jackets.

Embodiment

As shown in Figure 1, adopt zinc-plated copper free wire 1 to be conductor, extrude high density polyethylene (HDPE) PE insulating barrier 2 at zinc-plated copper free wire outer surface and constitute insulated wire cores (CAT5E UTP cable), wrapped aluminium-plastic tape phase-splitting screen 3 constitutes the branch phase lines on the line group of two eradication edge core pair twists.Wrapped high flame retardant polyvinyl chloride PVC inner sheath 4 on the cable core with four branch phase line strandings, the total screen 5 of braiding tinned copper wire on high flame retardant polyvinyl chloride PVC inner sheath 4, wrapped high flame retardant polyvinyl chloride PVC inner sheath 6 on the total screen 5 of tinned copper wire, 7 braidings of zinc-coated wire braiding armour are arranged on the high flame retardant polyvinyl chloride PVC inner sheath 6, extrude low smoke and zero halogen IXPE outer jacket 8 on zinc-coated wire braiding armour 7.

Claims

1, a kind of network data cable peculiar to vessel, the low smoke and zero halogen IXPE outer jacket that it is characterized in that being provided with total screen of tinned copper wire that wrapped high flame retardant polyvinyl chloride PVC inner sheath, braiding are set on cable core that four phase-splittings, eight heart yearns constitute and the cable core and zinc-coated wire armour and extrude, the total screen of tinned copper wire is arranged between the two-layer high flame retardant polyvinyl chloride PVC inner sheath, and low smoke and zero halogen IXPE outer jacket is extruded in zinc-coated wire armour outer surface.

2, network data cable peculiar to vessel according to claim 1 is characterized in that described phase-splitting is extruded by zinc-plated copper free wire outer surface that wrapped aluminium-plastic tape phase-splitting screen constitutes on the line group of insulated wire cores pair twist of high density polyethylene (HDPE) PE insulating barrier.
