To achieve the above object, the utility model provides following technical scheme：A kind of anti-shark formula submarine cable, including lead Body, elastoplast body and copper cash, the outer ring of the conductor are provided with conductor shield, and it is mounted between conductor shield Water-blocking conductor, the outer ring of the conductor shield is provided with insulating barrier, and the outer ring of the insulating barrier is provided with insulation screen, institute The outer ring for stating insulation screen sets semiconductive water blocking layer, and the outer ring of the semiconductive water blocking layer is provided with lead set, the elasticity The inner ring of plastic body, which is mounted with cable, and its outer surface, is enclosed with wrapped bed course, is wrapped up on the outer surface of the wrapped bed course There is the first steel wire, the outer ring of first steel wire is provided with dipping serving, and the outer ring of the dipping serving is provided with poly- second Alkene sheath, the outer ring of the pe sheath, which is enclosed with dope layer, the outer surface of the dope layer, is provided with projection, the copper The outer ring of line is enclosed with the second steel wire, and it is placed in the inside of plastic skeleton, is filled between the copper cash and the second steel wire Copper core, the outer ring of second steel wire is provided with copper pipe.

It is preferred that, the outer surface color of the dope layer is crocus.

It is preferred that, waterproof material is filled with the gap of second steel wire.

It is preferred that, the conductor and cable are provided with three groups altogether, and it is installed in the inside of elastoplast body.

It is preferred that, the plastic skeleton is shaped as U-lag.

Compared with prior art, the beneficial effects of the utility model are：The anti-shark formula submarine cable is in pe sheath Outer surface on wrap up dope layer, and the color of dope layer is crocus, has a kind of poison of crocus sea snake in the sea to shark Lethality is very big, and shark also closes to this snake as far as possible and it is remote it, so shark typically can in the case of conditioned reflex To orange very sensitive, therefore use the dope layer of crocus, can prevent shark close to and bite cable broken, while set projection, due to The thickness of projection can not only prevent that the reef and rock in seabed cause abrasion to cable in laying, while its projection can be just In cable is buried in seabed.
