Abstract
The invention discloses a multi-core high-and-low voltage composite submarine cable, comprising a cable core, wherein the cable core is formed by twisting two high-voltage power cables and two low-voltage cables, and an inner sheath; a galvanized steel wire armor layer and an outer protection layer are wrapped outside of the cable core in sequence; and asphalt as a waterproof filler is used among galvanized steel wires in the galvanized steel wire armor layer. The multi-core high-and-low voltage composite submarine cable has the advantages of good waterproof performance, corrosion resistance, long service life, high reliability, high mechanical strength and the like. By adopting the composite structure of the high-voltage and low-voltage cables, the construction workload is reduced, the construction period is shortened, the operation risk caused by multiple times of cable laying is reduced, the construction cost is saved and the cost is reduced.
Description
Technical field
The invention belongs to the power cable field, be specifically related to a kind of multicore high and low pressure composite submarine cable.
Background technology
When developing small-sized and marginal field, often rely on original macrotype platform, build the production platform of small-sized marginal field very simple and easy, that have even the small-sized and platform marginal field built up the simple and easy production platform that nobody that only have a small amount of critical process flow sheet equipment garrisons, control appliance to simple and easy production platform is arranged on the existing large-scale production platform, manages and controls by the Long-distance Control means.And to the electricity consumption of simple and easy production platform, generally be by submarine cable electrical source of power to be transported on the simple platform of not equipping the power station from the central platform that is provided with main electrical power plant.
On simple and easy production platform, be provided with simultaneously electric submersible pump equipment, navigation system and blind controller system.Equipment electricity consumption power supply requirement had both comprised the high voltage power power supply that the latent pumping system of power supply uses; Comprise again the low-voltage-powered power supply for navigation system and blind controller system.There are high voltage frequency conversion system and low pressure power frequency system doubling need for electricity.Because simple and easy production platform unattended operation; do not arrange simultaneously the room of relevant device; therefore the electric submersible pump control panel and the electric submersible pump transformer that newly increase oil well are arranged on the macrotype platform; in order to guarantee the independence of the electric submersible pump control on each fender bracket, need to use power supply to power to electric submersible pump respectively simultaneously.Therefore, simple platform wellhead protecting frame requirement of engineering macrotype platform is given power supply, and each simple platform needs high voltage source and low-tension supply.
Application standard form submarine cable also can solve whole technical problems, but the shortcoming that exists is exactly that expense is very high.The submarine cable of standard is three-core cable, each simple platform needs many independently submarine cables like this, because the restriction of the work capacity of the existing working ship that builds a submarine cable, can only lay and install 1 submarine cable at every turn, each simple and easy production platform needs to carry out repeatedly the work of laying of submarine cable like this, marine job engineering amount is very large, need to expend a large amount of time; In addition, corresponding submarine cable " J " type pillar also needs to install many with it, and the submarine cable junction box need to install a plurality of, and the floor space of the simple and easy production platform that nobody garrisons just needs to increase, and overall construction intensity just needs to strengthen; This certainly will cause engineering overall work amount to increase, and corresponding prolongation of duration causes the operating cost of offshore construction to increase.
Summary of the invention
The purpose of this invention is to provide a kind of water proofing property, corrosion-resistant, long service life, reliability is high, mechanical strength is higher, reduce the construction working amount, reduces the multicore high and low pressure composite submarine cable of construction period.
A kind of multicore high and low pressure composite submarine cable of the present invention comprises cable core, and described cable core is by two high-voltage power cables and two stranded forming of low-voltage cable, coats successively inner sheath, zinc-coated wire armour and outer jacket outside cable core.
Described high-voltage power cable comprises: the power cable cable core, and its power cable cable core is by three stranded forming of power core; Outside the power cable cable core, coat successively polyethylene bedding, copper strip shielding layer and the first oversheath.
Described low-voltage cable comprises: the low-voltage cable cable core, and its low-voltage cable cable core is by three stranded forming of low pressure core; Outside the low-voltage cable cable core, coat successively inner covering, the second lead sheath layer, polyethylene isolation layer, steel band screen and the second oversheath.
Described power core is by the power conductor and is extruded in the external conductor shield of power guide, insulating barrier, insulation screen, peninsula electric expansion belt, the first lead sheath layer, pe sheath layer and consists of.
Described low pressure core is by conductor and is extruded in the outer insulating layer of conductor of conductor and consists of.
Use pitch to fill as waterproof in the described zinc-coated wire armour between the zinc-coated wire.
Beneficial effect of the present invention is:
The present invention has been twined again one deck steel band screen for behind the high-tension cable stranding in its outside, solved the problem of disturbing between the high and low pressure cable.This submarine cable has also been used the power carrier technology simultaneously, namely by high-voltage power cable, the sampled signal of downhole sensor is sent to the manned platform, shows the operating state of down-hole electric submersible pump.The present invention has that water proofing property, corrosion-resistant, long service life, reliability are high, mechanical strength is than advantages of higher, when laying, avoided simultaneously the repetition operation, reduced the construction working amount, reduced the construction period, the operating risk of having avoided repeatedly extra large cable to lay, save project cost, reduced cost.
