Description
Technical field
The utility model discloses a kind of three core photoelectric composite submarine cables, especially belong to the submarine cable field.
Background technology
It is a large-scale engineering that difficulty is complicated that the submarine cable technology is known as by countries in the world, no matter is that design, manufacturing, the difficulty of construction of cable all is higher than other cable product out and away.Because extra large cable environment for use is that the large degree of depth, external force circumstance complication, biology, chemistry and physical damage are serious, particularly in the seabed of the large degree of depth, huge hydraulic pressure requires cable to have good block-water performance and mechanical performance.
As everyone knows, because extra large cable is used for island to the continent, island are to island, platform is to island, platform is to the electric power in continent and the transmission of communication, joint length is generally several kilometers even tens kilometers, involve great expense, in case break down then mean salvaging and the maintenance of whole cable, even scrap, because extra large cable environment for use is the large degree of depth, the external force circumstance complication, biological, chemistry and physical damage are serious, particularly in the seabed of the large degree of depth, huge hydraulic pressure requires cable to have good block-water performance and mechanical performance, to avoid the generation of fault, bring about great losses.
The patent No. having occurred subsequently is 201120226927.9, and the applying date is on June 30th, 2011, and denomination of invention is a kind of patented technology scheme of photoelectric composite submarine cable, although this patented technology is from having solved to a great extent waterproof, corrosion-resistant problem.But, owing in this patented technology scheme, adopted normal conductor, so that the threat that cable still can be corroded for a long time in complicated rugged environment; It has adopted aluminium-plastic tape, because the waterproof effect of aluminium-plastic tape is not good, so, the waterproof effect of the cable in this patented technology is slowly undesirable, because the armour in this patented technology only has individual layer, therefore, can not bear the outer force environment of sea bottom complex, make the cable core of extra large cable inside and light unit affected by tension force, and then the mechanical performance of cable and electrical property are descended.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of length large, blocks water, waterproof, antiseptic property be good, the cable that mechanical performance is good.
For realizing above-mentioned technical purpose, the technical solution of the utility model is as follows:
A kind of three core photoelectric composite submarine cables, comprise three core conductor cores 1, two core light unit 10, every conductor thread core 1 skin all is disposed with conductor shield 3, crosslinked polyetylene insulated layer 4, insulation screen 5, semi-conductor electricity blocks water and is with 6 and polythene PE inner sheath 8, described three core conductor cores 1 and two core light unit, 10 stranded formation cable cores, described cable core also is disposed with rubber strap 11 outward, wire armoring layer 12, PP rope and anti-corrosion asphalt layer 13, also comprise the packing 9 that is filled between cable core and the rubber strap 11, it is characterized in that, described conductor thread core 1 also is provided with conductor waterstop 2 for including the water blocking yarn conductor between described every conductor thread core 1 skin and the conductor shield 3.
The semi-conductor electricity of every conductor thread core 1 described in the utility model block water be with 6 and polythene PE inner sheath 8 between also be provided with seamless plumbous cover 7.
Be coated with anti-corrosion asphalt on the seamless plumbous cover 7 described in the utility model.
Because the utility model has adopted technique scheme, therefore have the following advantages:
(1) chance of the water blocking yarn in conductor water expands rapidly, fills slit between the conductor monofilament, stops water along the cable longitudinal flow, the outer wrapped waterstop of conductor and insulation shielding is met water and is expanded rapidly, and the generation jelly, the space between filling and the skin stops water along the cable longitudinal flow.
(2) lead has farthest been avoided the radially intrusion of water along cable as the best metal material of block-water performance, and anti-corrosion asphalt guarantees the decay resistance of lead sheath.The PE inner sheath has good radial water-resisting performance.
(3) the outer force environment that wrapped rubber strap and double wire armor structure can better be born sea bottom complex behind the stranding makes the cable core of extra large cable inside and light unit avoid tension force.
(4) the PP rope adds water-tight corrosion-proof pitch, has guaranteed the mechanical performance of cable serving.
