The invention discloses a special power cable for seabed. The special power cable is used for power transmission at the seabed and comprises a plurality of main wires and a plurality of auxiliary wires; one of the main wires is a signal transmission wire; conducting cable cores and polymerization materials are arranged in the power transmission main wires and the auxiliary wires; the signal transmission wire comprises four signal transmission sub wires and optical cables which are at least partially located in a pore space among the sub wires; the sub wires comprise a plurality of signal transmission cable wires and shielding layers; the sub wires and the optical fibers are wrapped by the polymerization materials; an insulation material fills and wraps the main wires and the auxiliary wires into a whole; a cladding layer which is formed by wrapping an aluminium plastic composite belt is arranged on the periphery of the insulation material; a waterproof layer is arranged on the periphery of the cladding layer; a protection sheath is arranged on the periphery of the waterproof layer; an armor layer which is formed in a way that a plurality of aluminium wires wrap the cladding layer along the oblique lines is arranged between the waterproof layer and the cladding layer; the aluminium wires which form the armor layer comprise aluminium core bodies which are located in the center and tin layers covering the aluminium core bodies; a tin metal layer is arranged between the cladding layer and the armor layer.
Description
technical field [0001] The invention relates to the technical field of power cables, in particular to a submarine special power cable. Background technique [0002] With the rapid development of the economy, submarine cables have been widely used, and the requirements for submarine cables are also getting higher and higher. The submarine environment is highly corrosive, and the cable is generally equipped with a shielding layer for anti-interference requirements. An induced potential will be generated on the shielding layer, resulting in serious eddy current and hysteresis loss, which will aggravate the corrosion hazard and shorten the cable life. service life. Due to the difficulty in laying submarine cables, the frequent replacement of submarine cables caused by the short service life will cause huge economic losses. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a submar...
