Abstract

The utility model discloses a computer cable for ships and offshore platforms. The computer cable comprises multiple conductor groups and insulating layers; each conductor group is formed by twisting two conductors wrapped with the insulating layers; the thickness of each insulating layer is 0.6-0.7mm; the outer side of each conductor group is wrapped with an inner belting layer; color belts are arranged between the inner belting layers and the insulating layers; the outer side of each inner belting layer is sequentially wrapped with a sub-shielding layer and a middle belting layer; the multiple conductor groups, after being wrapped with the middle belting layers, are sequentially wrapped with an outer belting layer and a main shielding layer; and the outer side of the main shielding layer is sequentially wrapped with an inner lining layer, an armor layer and an outer sheath layer. The utility model provides the computer cable for ships and offshore platforms, performance indexes such as low smoke, no halogen, flame retardation and the like required by computer cables for ships and offshore platforms are met, and problems of humidity proofing and anticorrosion are solved.

Description

A kind of boats and ships and pier computer cable

Technical field

The utility model relates to cable industry, is specifically related to a kind of boats and ships and pier computer cable.

Background technology

Shipboard cable is electric power, illumination, the control of rivers, ocean and aquatic building platform, the cable of system-specific such as communicate by letter.The boats and ships transportation is transported main mode as worldwide logistics, always in occupation of very important effect.Since stepping into 21 century, Southeast Asia is transferred at the center of world's shipbuilding industry gradually, and China also progressively becomes shipbuilding processing area the biggest in the world, is promoting the development of world's shipbuilding industry.

Traditional boats and ships and pier are a topic that is difficult to resolve with computer cable for oil resistant, anticorrosion problem in the actual working environment always.

The utility model content

The purpose of this utility model provides a kind of boats and ships and pier computer cable, satisfies boats and ships and pier cable and has low cigarette, Halogen, performance index such as fire-retardant, solves moistureproof, anticorrosion problem simultaneously.

Scheme of the present utility model is as follows: a kind of boats and ships and pier computer cable, comprise several conductor groups, insulating barrier, described several conductor groups constitute by the conductor of two wrap insulate layers is stranded respectively, described thickness of insulating layer is 0.6mm-0.7mm, described several conductor group outsides are enclosed with interior belting layer respectively, be provided with colour band between belting layer and the insulating barrier in described, belting layer is enclosed with sub-shield outward successively in described, middle belting layer, several conductor group outsides in the parcel behind the belting layer are enclosed with outer belting layer successively, total screen, described sub-shield, total screen adopts tinned copper wire to weave, count is not less than 90%, and described total screen is enclosed with inner covering outward successively, armour, external sheath layer.

Described insulating layer material is the flame-proof cross-linking polyolefin.

Belting layer employing thickness is the wrapped formation of polyester film of 0.05mm in described, and the wrapped rate of putting up is 25%-30%,

Described inner covering adopts the corrosion-resistant polyolefin of high flame resistance, low smoke Halogen to extrude formation.

Armour of the present utility model adopts the tinned copper wire braiding to constitute, count is higher, has the favorable mechanical protective value, effectively protects cable internal electric performance structure not to be subjected to the influence of external environment, be insulating material with the flame-proof cross-linking polyolefine material, have good flame retardant property; Halogen gas, gas pH value of water solution and the conductivity of overflowing during the cable material burning are low, have the low-corrosiveness energy; It is few to generate smog during cable fire, and possesses performances such as wear-resisting, anti-tear, oil resistant, anti-ozone, corrosion-resistant, high flame retardant.

Description of drawings

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

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Boats and ships and pier computer cable, comprise several conductor groups 1, insulating barrier 2, several conductor groups 1 constitute by the conductor 3 of two wrap insulate layers 2 is stranded respectively, insulating barrier 2 thickness are 0.6mm-0.7mm, several conductor group 1 outsides are enclosed with interior belting layer 4 respectively, be provided with colour band between interior belting layer 4 and the insulating barrier 2, the interior belting layer 4 outer sub-shields 5 that are enclosed with successively, middle belting layer 6, it is the wrapped formation of polyester film of 0.05mm that middle belting layer 6 adopts thickness, the wrapped rate of putting up is 25%-30%, several conductor group 1 outsides in the parcel behind the belting layer 6 are enclosed with outer belting layer 7 successively, total screen 8, sub-shield 5, total screen 8 adopts tinned copper wire to weave, total screen 8 outer inner coverings 9 that are enclosed with successively, armour 10, external sheath layer 11, conductor 3 adopts the stranded bunchy of several tinned copper wires to constitute, and conductor 3 sectional areas are 0.75-2.5 mm ², insulating barrier 2 roundness are less than 0.8 times, and material adopts crosslinked polyethylene, and external sheath layer 11 materials adopt the corrosion-resistant polyolefin of fire-retardant Halogen, and armour 10 adopts the tinned copper wire braiding to constitute, and count is not less than 90%.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
