Background technology:
The development of China's oil platform cable is started in the eighties in last century.Under the springing up of exploitation China offshore petroleum resources upsurge, Zhang Zhiqing at that time, Shengyang Electrical Cable Factory, red flag cable factory etc. possess the factory of shipboard cable manufacturing capacity, all once develop the offshore oil platform cable.But the macrotype platform in China's marine site probing and oil recovery all was foreign platform basically at that time, and small-sized platform is homemade.Even homemade platform also proposes to use the platform cable of foreign country, and homemade platform cable is almost completely kept outside of the door.
Because it is very high that the every technical performance of oil platform cable requires, 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 GJB1916-94 " naval vessel with low smoke cables and flexible cord general specification ", 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 naval vessel cable domesticize.
Along with the raising of China's electric wire technology, China has had many factories can make the offshore oil platform cable now, comprising the various electric power that use on sea floor optoelectronic composite cable and the platform, communication and instrument and meter electric wire.The production domesticization of oil platform is independently supplied, is substituted import for China's platform cable good market condition is provided.
At present, in " electric wire production development project study ", mention in country's the ninth five-year plan and 2010 imagination: from current demand of user and development from now on, key is to go up level (quality level and technical merit), the kind of development derivation, extension type, combined, compact, and the kind of studying some high-tech performances, for example low smoke, zero halogen low toxicity type Plastic-sheathed Cable and plastic cable, medium pressure grade shipboard cable.
Traditional ocean engineering is a topic that is difficult to resolve with cable for oil resistant, anti-mud problem in the actual working environment always, the utlity model has low cigarette, Halogen, performance index such as fire-retardant, and this cable has also solved oil resistant, anti-mud problem.The armour that has adopted the tinned copper wire braiding to constitute simultaneously can be used as screen simultaneously, and count is higher, replaces screen, has good shielding properties, and good anti-external electromagnetic field disturbs and do not produce external interference.
The utility model content:
The purpose of this utility model provides a kind of ocean engineering power cable, satisfies ocean engineering cable and has low cigarette, Halogen, performance index such as fire-retardant, and this cable has also solved oil resistant, anti-mud problem.

The ocean engineering power cable comprises three conductors, insulating barrier, and described cross-sectional area of conductor is long-pending to be 1.0～400mm
2It is characterized in that: described three conductors outside is enclosed with insulating barrier respectively, three mutual stranded bunchys of conductor behind the wrap insulate layer, the insulating barrier outside is enclosed with belting layer behind the bunchy, be provided with the packed layer of nonwoven fabrics as filler between described belting layer and the insulating barrier, the described belting layer outside is enclosed with inner covering, armour, and described armour adopts the tinned copper wire braiding, count is not less than 90%, and the described armour outside is enclosed with fire-retardant Halogen oil resistant mud polyolefin jacket layer.
Described ocean engineering power cable is characterized in that: described insulating layer material is a cross-linked polyolefin.
Described ocean engineering power cable is characterized in that: described belting layer adopts the overlapping wrapped formation of one or more layers band.
Described ocean engineering power cable is characterized in that: described inner covering adopts high flame retardant halogen-free polyolefin material to extrude formation.
The selected material of the utility model is:
(1) conductor.Conductor material is that oxygen-free copper bar draws the lead that forms.Conductor should adopt the 5th kind of copper or the tin-coated copper conductor of stipulating among the GB/T3956.Cross-sectional area of conductor is generally 1.0～400mm
2Especially for the heavy in section power cable, adopt the 5th class conductor not only to be easy to lay, soft more simultaneously, bending property is better, more is applicable to oil platform drillng operation demand.
(2) insulation.Ocean engineering is a cross-linked polyolefin with the insulating material that power cable adopts.This material has physics, chemical property and the high and low temperature resistance of excellent electrical insulation capability, excellence; Excellent flexibility performance and anti-wear performance; Excellent low cigarette, Halogen characteristic.
(3) cable element.The cable core gap adopts halogen-free flameproof glass cordage material to fill, so that the outward appearance rounding.Band adopts fire-retardant band wrapped, and outer wrapped one or more layers band of cable core is tightened, and prevents that cable core is loose in the laid processes.
(4) inner covering.Extrude high flame retardant halogen-free polyolefin material, surperficial shall be rounded up is smooth.
(5) braiding armouring.Armouring adopts the tinned copper wire braiding, and it has the double action of mechanical protection and shielding concurrently, and count is according to IEC 60092-350 standard code, and count is not less than 90%.
