Abstract
The utility model discloses a high-voltage seabed electric cable, comprising a conductor, an insulation layer, a buffering layer, a lead sleeve, an inner protection layer, an inner covering, an armoured layer, and a serving layer, which are arranged from the inside to the outside. The utility model is characterized in that at least one optical cable unit is embedded in the inner protection layer, and has the advantages that the optical cable units are embedded in the inner protection layer, and are protected by the inner protection, and are not flattened by the external compression, thereby the transmitting performance of optical fiber is guaranteed, and the best performance price ratio can be achieved when the thickness of the inner protection layer is 1.5mm thicker than the diameter of the cable units, and the optical units adopt stainless steel sleeves, which are convenient, practical, safe, and reliable. In addition, the manufacturing and laying cost is greatly saved by the structure of the entire electric cable which is not only can be used for transmitting electric power, but also can be used for transmitting communication signal, and the usage is extensive.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of high pressure submarine cable.
Background technology
Development along with telecommunications and island electric power, photoelectricity will be in conjunction with will be more and more general, and the use of 110kV and above high pressure submarine cable will constantly increase, but the high pressure submarine cable generally all adopts single cored structure, and this gives the compound increase certain degree of difficulty of photoelectricity.
The patent No. is that the optical fiber that discloses a kind of incorporated longer-sized incorporated subaqueous unit in the Chinese invention patent specification of ZL90107807.7 comprises be arranged in the plastic sheath inner face purchased on the longer size underwater units core body periphery or the optical fiber of outside such as power cable or water supply line.Each fiber assembly comprises an optical fiber that is received in its peripheral cated metal tube, described coating is higher than the synthetic resin material of the fusing point of plastic casing material and makes by its fusing point, and the outside of the plastic sheath on the core body periphery provides the armouring iron wire again, prevent any bending of fiber assembly thus, but fiber assembly is set to one deck separately in this structure, be vulnerable to the extruding of cable outer layer and fiber assembly is crushed easily, thereby influence the transmission performance of optical fiber.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of distortion that can effectively prevent optical fiber component, thereby guarantees the high pressure submarine cable of Optical Fiber Transmission performance.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of high pressure submarine cable, comprise the conductor, insulating barrier, resilient coating, plumbous cover, sheath, inner covering, armour and the serving that set gradually from inside to outside, be embedded with at least one optical cable unit in the described sheath.
Described optical cable unit comprises the stainless steel sleeve pipe and is arranged at least one interior optical fiber of described stainless steel sleeve pipe.
The thickness of described sheath is than the big 1～2mm of external diameter of described optical cable unit.
The thickness of described sheath is than the big 1.5mm of external diameter of described optical cable unit.
Compared with prior art, the utility model has the advantages that the optical cable unit is embedded in sheath, the optical cable unit is subjected to the protection of sheath and can be crushed because of the extruding of outside, thereby guaranteed the transmission performance of optical fiber, and the thickness of sheath can obtain best cost performance during than the big 1.5mm of diameter of optical cable unit; The optical cable unit adopts the stainless steel sleeve pipe, and is not only convenient and practical but also safe and reliable; In addition, the structure of whole cable has been saved manufacturing greatly and laid expense, can be used for transferring electric power, can be used for the transmission communication signal again, and is of many uses.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of optical cable of the present utility model unit.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of high pressure submarine cable, comprise the conductor 1, insulating barrier 2, resilient coating 3, plumbous cover 4, sheath 6, inner covering 7, armour 8 and the serving 9 that set gradually from inside to outside, evenly be embedded with optical cable unit 5 in the sheath 6, optical cable unit 5 comprises stainless steel sleeve pipe 52 and 3 optical fiber 51 that are arranged in the stainless steel sleeve pipe 52, and the thickness of sheath 6 is than the big 1.5mm of external diameter of optical cable unit 5.
In the foregoing description, the optical cable unit 5 that is embedded in the sheath 6 can be in sheath 6 arranged distribution arbitrarily, and quantity is at least one, the optical fiber 51 in the stainless steel sleeve pipe 52 also are at least one; In addition, the thickness of sheath 6 can change arbitrarily in than the scope of the big 1～2mm of external diameter of optical cable unit 5.
