Abstract
The utility model discloses a composite cable for an offshore oil platform, which comprises three large conductors, two small conductors and insulating layers. Each of the three large and two small conductors is wrapped in one flame-retardant crosslinked polyolefin insulating layer; after wrapped and insulated, the two small conductors are intertwisted and then lapped, braided and shielded to form a line pair, and the line pair is intertwisted and bundled with the three large conductors to form a cable core; the bundled cable core is wrapped in a belting layer, wherein flame-retardant fiber glass ropes as a filling layer are arranged between the belting layer and the insulating layers; the belting layer is wrapped in an inner lining layer; the inner lining layer is wrapped in an armored layer, wherein the armored layer employs large-size thick galvanizing steel wire for armoring, and the maximum armoring gap of the thick steel wires is no more than 2.5mm; asphalt smearing is carried out; and the armored layer is wrapped in a high-flame-retardation low-smoke halogen-free oil-slurry-resistant polyolefin sheath layer. The composite cable for the offshore oil platform provided by the utility model satisfies low-smoke, halogen-free, flame-retardant and other performance indexes for offshore oil platform cables, and at the same time solves oil resistant and slurry resistant problems.
Description
Technical field
The utility model relates to cable industry, is specifically related to a kind of offshore oil platform composite cable.
Background technology
The development of China's oil platform series 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 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 domestic.Even Domestic Platform also proposes to use the platform cable of foreign country, 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 offshore oil platform is a topic that is difficult to resolve with composite cable for oil resistant, anti-mud problem in the actual working environment always.
The utility model content
The utility model provides a kind of offshore oil platform composite cable, satisfies low cigarette that offshore oil platform cable has, Halogen, the performance index such as fire-retardant, and this cable has also solved anti-mud, oil resistant problem simultaneously.
Scheme of the present utility model is as follows: a kind of offshore oil platform composite cable, comprise three large conductors and two little conductors, insulating barrier, described three large conductors and two little conductor outsides are enclosed with respectively the flame-proof cross-linking polyolefin insulation layer, carry out pair twist after two little conductor wrap insulate and carry out wrapped braid shielded forming line to group, line is to group and three stranded bunchys of large insulated wire cores, 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, the described belting layer outside is enclosed with inner covering, the described inner covering outside is enclosed with armour, described armour adopts large specification lagging cover zinc wire armoring, thicker wire armouring maximal clearance is no more than 2.5mm, and smear bitumen treatment, the described armour outside is enclosed with the high flame resistance, low smoke Halogen oil resistant polyolefin jacket of anti-mud layer.
Described large cross-sectional area of conductor is long-pending to be 25～300m mm
2, little cross-sectional area of conductor is long-pending to be 1.0mm
2
Described belting layer adopts the overlapping wrapped formation of one deck aluminium strip.
Described line adopts the tinned copper wire braiding to the shielding of group.
Armour of the present utility model adopts the core composite construction, three large conductors are used for electric power transfer, and two little conductors are used for the signal transmission, and separated-shielding protection is arranged, reduce the interference of external electromagnetic ripple, armour adopts lagging cover zinc wire armoring, and wire gauge is large, and hardness is high, has extraordinary prevention mechanical damage characteristic, smear pitch and prevent that effectively seawater to corrosion and the embrittlement of steel wire, being insulation with the flame-proof cross-linking polyolefine material, have 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; It is few to generate smog during cable fire, and possesses the performances such as wear-resisting, anti-tear, oil resistant, anti-ozone, corrosion-resistant, anti-mud, high flame retardant.
