Abstract

The utility model discloses a variable-frequency cable for ships and offshore platforms. The cable comprises conductors and insulating layers, wherein the outer sides of the conductors are wrapped with the insulating layers; after the conductors are wrapped with the insulating layers, large wire cores and small wire cores are distributed alternately; then the insulated wire cores are twisted into a bundle to form a cable core, of which the outer side is wrapped with a belting layer; a flame-retardant glass fiber rope serving as a filling layer is arranged between the belting layer and the insulating layers; the belting layer is wrapped with a shielding layer which is woven with copper wires, wherein the weaving density is not smaller than 90 percent; the outer side of the shielding layer is wrapped with an inner lining layer and an armor layer; the armor layer is woven with tinned copper wires, wherein the weaving density is not smaller than 90 percent; and the outer side of the armor layer is wrapped with a high-flame-retardation low-smoke halogen-free corrosion-resistant polyolefin sheath layer. Performance indexes such as low smoke, no halogen, flame retardation and the like required by variable-frequency 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 frequency-changing cable

Technical field

The utility model relates to a kind of boats and ships and pier frequency-changing 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.

Because it is very high that boats and ships and pier require with the every technical performance of cable, domestic development is started late.For realizing the production domesticization of oil drilling facility-specific cable, domestic have cable factory to succeed in developing 3kV and following offshore oil and boats and ships power cable with reference to international standard IEC60092 " shipboard cable manufacturing standard ", CCS " steel seagoing vessel classification rules ", " maritime affairs labour pact ", Japanese Electric Committee Standard JIS 4910 " boats and ships and overseas platform cable ", the standard IEEE 45-1998 of AAEE " the boats and ships electrical installation rules that IEEE recommends " and French NEXANS company, realized that tentatively boats and ships and pier domesticize with cable.

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

The utility model content

The utility model provides a kind of boats and ships and pier frequency-changing cable, satisfies boats and ships and levelling bench cable and has low cigarette, Halogen, performance index such as fire-retardant, and this cable has also solved moistureproof, anticorrosion problem.

Scheme of the present utility model is as follows: a kind of boats and ships and pier frequency-changing cable, comprise conductor, insulating barrier, the described conductor outside is enclosed with insulating barrier respectively, behind the wrap insulate layer core is pressed small one and large one spaced apart, the stranded bunchy of insulated wire cores then, the cable core outside is enclosed with belting layer behind the bunchy, be provided with the flame retardant type glass cord between described belting layer and the insulating barrier as packed layer, described belting layer outer wrapping screen, described screen adopts the copper wire braiding structure, count is not less than 90%, the described screen outside is enclosed with inner covering, armour, described armour adopts the tinned copper wire braiding, and count is not less than 90%, and the described armour outside is enclosed with the corrosion-resistant polyolefin jacket layer of high flame resistance, low smoke Halogen.

Described cross-sectional area of conductor is long-pending to be 25～300 mm ², the core number is the 3+3 core.

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

Described belting layer adopts the overlapping wrapped formation of one or more layers fire-retardant oxygen barrier band.

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

Cable core of the present utility model adopts 3+3, and small one and large one is alternately arranged, reduced the electromagnetic stack of frequency-changing cable, kept the good rounding property of cable simultaneously, screen adopts the copper wire braiding to constitute, the count height, has the anti-tampering characteristic of outstanding shielding, armour adopts the tinned copper wire braiding to constitute, count is higher, have very strong mechanical protection performance, strengthened the shielding properties of cable simultaneously, good anti-external electromagnetic field disturbs and does not produce external interference, be insulation 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.
