Abstract
The utility model discloses a computer cable for an offshore oil platform. The computer cable comprises multiple groups of conductors and insulation layers, wherein each group of conductors is formed by twisting two conductors wrapped with insulation layers; thickness of each insulation layer is 0.6 to 0.7mm; the outside f each group of conductors is wrapped with an inner wrapping tape layer; a color belt is arranged between each inner wrapping tape layer and each insulation layer; the outside of each inner wrapping rape layer is wrapped with an sub-shielding layer and a middle wrapping tape layer sequentially; each middle wrapping tape layer is formed by lapping a polyester film of 0.05mm with a lapping cover rate of 25 to 30%; the multiple groups of conductors, after wrapped by the middle wrapping tape layers, are wrapped with an outer wrapping tape layer and a main shielding layer sequentially; the sub-shielding layers and the main shielding layer adopt a method of overlapping aluminum-plastic composite tapes with a thickness being no less than 0.08mm; each aluminum-plastic composite tape takes a plastic thin film as a base material and is formed with one surface or both surfaces coated with aluminum powder, and during the wrapping the aluminum surface is arranged inward; the sub-shielding layers and the main shielding layer are separately provided inside with a drainage wire twisted by multiple tinned copper wires with the cross section of the drainage wire being no less than 0.3mm<2>; and the outside of the main shielding layer is wrapped with an inside liner, an armored layer and an outer protective sheath layer sequentially. The computer cable solves problems such as poor cable shielding effect, explosion of explosive gas, cable self capacitance and distributed inductance caused by electric sparks and heat effect, and at the same time, solves problems of oil resistance and slurry resistance.
Description
Technical field
The utility model relates to cable industry, is specifically related to a kind of offshore oil platform computer cable.
Background technology
The development of China's oil platform series cable is started in the eighties in last century.At exploitation China offshore petroleum resources
Under the springing up of upsurge, Zhang Zhiqing at that time, Shengyang Electrical Cable Factory, red flag cable factory etc. possess shipboard cable manufacturing energy
The factory of power all once developed offshore oil platform cable.But, at that time the probing of China marine site and recover the oil large
The type platform all is foreign platform basically, and small-sized platform is domestic.Even Domestic Platform also proposes to use the flat of foreign country
The platform cable, and the Domestic Platform cable is almost completely kept outside of the door.
Because the every technical property requirements of petroleum platform cable is very high, domestic development is started late.For realizing the production domesticization of oil drilling facility-specific cable, domestic have cable factory to succeed in developing 2000V and following offshore oil and warship ship power cable with reference to military standard GJB1916-94 " naval vessel with low smoke cables and flexible cord general specification ", Norway electrical standard NEK606-2009 " offshore platform with Halogen/anti-mud cable ", the standard IEEE 45-1998 of AAEE " the boats and ships electrical installation rules that IEEE recommends " and the requirement of the U.S. DAA-1048B of SURPENANT company technical specification, realized that tentatively oil platform and ship cable domesticize.
Traditional ocean engineering is a topic that is difficult to resolve with computer cable for oil resistant, anti-mud problem in the actual working environment always.
The utility model content
Of the present utility modelly provide a kind of offshore oil platform computer cable, solved the cable shield effect relatively poor, because electric spark and thermal effect cause the problem of explosion hazard gases blast and cable selfcapacity and distributed inductance, also solved simultaneously oil resistant, anti-mud problem.
Scheme of the present utility model is as follows: a kind of offshore oil platform computer cable, comprise several conductor groups, insulating barrier, described several conductor groups consist of 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 respectively interior belting layer, be provided with colour band between described interior belting layer and the insulating barrier, described interior belting layer is enclosed with sub-shield outward successively, middle belting layer, it is the wrapped formation of polyester film of 0.05mm that described middle belting layer adopts thickness, the wrapped rate of putting up is 25%-30%, 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 the overlapping wrapped mode of aluminium-plastic tape that is not less than 0.08mm, aluminium-plastic tape is by take plastic film as base material, single or double applies aluminium powder and makes, and aluminium is towards interior during coating; Described sub-shield, total screen are respectively equipped with stranded drainage thread of multiply tinned copper wire of interior placement, and the drainage thread cross section is not less than 0.3mm
2, described total screen is enclosed with inner covering, armour, external sheath layer outward successively.
Described conductor adopts the stranded bunchy of several tinned copper wires to consist of, and described cross-sectional area of conductor is long-pending to be 0.75-2.5 mm
2
Described insulating barrier roundness is less than 0.8, and material adopts crosslinked polyethylene.
Described inner covering material adopts high flame resistance, low smoke Halogen oil resistant mud polyolefin.
Described armour adopts the tinned copper wire braiding to consist of, and count is not less than 90%.
Described external sheath layer material adopts high flame resistance, low smoke Halogen oil resistant mud polyolefin.
The utility model flame-retardant crosslinking polyethylene is insulation, helps to reduce mutual capacitance, improves insulation resistance, improves voltage-resistent characteristic, has good fire resistance; 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; Generate smog during cable fire few.Cable has low electric capacity and low inductance; And possess the performances such as wear-resisting, anti-tear, oil resistant, anti-ozone, oil resistant mud, high flame retardant, secondly, cable has good shielding properties, and good anti-external electromagnetic field disturbs and do not produce external interference.The cable of aluminium-plastic tape shielding, external diameter is little, lightweight, soft, moistureproof, and shield effectiveness is good
