Description

Marine network data cable

technical field

The utility model relates to a structure of a cable, in particular to a structure suitable for a supporting cable for a ship network, and belongs to the technical field of cables.

Background technique

With the continuous advancement of science and technology, the application of computers in ships is becoming more and more extensive and popular. It not only provides convenience for the daily office work of ships, but also provides a guarantee for the safe production of ships, the improvement of work efficiency, and the standardization of ship operations. necessary conditions. In recent years, with the development of network technology, especially the injection of LAN, the local area network in the ship has risen, installed and used, which provides convenience for the sharing of information resources of the ship and the transmission and transfer of data. Management has opened up new ideas. In the entire network, the network cable is one of the most important components, and it acts as a core link for information transmission. Because the hull is greatly affected by the external environment and marine climate, especially under the harsh conditions of roll, pitch, temperature, salt spray, humidity, radiation, etc. in a wide water environment, coupled with the narrow space inside the ship, various equipments are dense and interfere with each other. very serious. In view of the above situation, it is an urgent task for cable research and production enterprises to develop a marine network data cable to meet the requirements of modern ship network.

Utility model content

The purpose of the utility model is to provide a ship network data cable to meet the needs of the modern ship network market.

The purpose of this utility model is achieved in this way. The marine network data cable is characterized in that it is provided with a cable core composed of four-phase eight-core wires and a wrapped high flame-retardant polyvinyl chloride PVC inner sheath and braided cable core. Tinned copper wire overall shielding layer, galvanized steel wire armor layer and extruded low-smoke halogen-free irradiation cross-linked polyethylene outer sheath, tinned copper wire overall shielding layer is set on two layers of high flame-retardant PVC Between the PVC inner sheaths, the outer sheath of low-smoke halogen-free radiation cross-linked polyethylene is extruded on the outer surface of the galvanized steel wire armor.

The phase separation is composed of tinned oxygen-free copper wires whose outer surface is extruded with a high-density polyethylene PE insulation layer, and an aluminum-plastic composite tape phase-separation shielding layer wrapped around a pair of twisted wire groups with insulated cores.

The utility model has reasonable and compact structure and small volume. The product adopts 4 pairs of 8-core super-category 5 wires as cable cores, and is equipped with aluminum-plastic composite tape wrapped phase-separated shielding layer and tinned copper wire braided overall shielding layer, and adopts double-layer inner sheath plus armored layer and outer sheath. It has comprehensive properties such as flame retardant, anti-interference, anti-collision, anti-humidity, anti-salt spray, anti-mold, anti-weather, high-speed data transmission and accurate, stable and reliable. It is an ideal network data cable, especially suitable for modern ships and naval computer networks, as a signal transmission line.

Description of drawings

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

In the figure: 1 tinned oxygen-free copper wire, 2 insulating layer, 3 phase-splitting shielding layer, 4 inner sheath, 5 overall shielding layer, 6 inner sheath, 7 armoring layer, 8 outer sheathing layer.

Detailed ways

As shown in Figure 1, a tinned oxygen-free copper wire 1 is used as a conductor, and a high-density polyethylene PE insulating layer 2 is extruded on the outer surface of the tinned oxygen-free copper wire to form an insulated wire core (super-category five wires). The phase-splitting shielding layer 3 wrapped with an aluminum-plastic composite tape forms a phase-splitting line on the twisted wire group of wire cores. A cable core made of four phase-separated wires is wrapped with a high flame-retardant polyvinyl chloride PVC inner sheath 4, and a tinned copper wire overall shielding layer 5 is braided on the high flame-retardant polyvinyl chloride PVC inner sheath 4. The overall shielding layer 5 of tinned copper wire is wrapped with a high flame-retardant polyvinyl chloride PVC inner sheath 6, and the galvanized steel wire braided armor layer 7 is braided on the high flame-retardant polyvinyl chloride PVC inner sheath 6. The steel wire braided armor layer 7 is extruded with an outer sheath layer 8 of low-smoke halogen-free irradiation cross-linked polyethylene.
