The invention discloses a photoelectric composite
submarine cable repair joint, which comprises a cylinder and cover boards arranged on two ends of the cylinder, the
submarine cable penetrates the cover boards and jointed in the cylinder, the cover board is provided with an airproof fixation piece, a set of
electricity conductive drawbars electrically connected with the airproof fixation piece is arranged between the airproof fixation piece and the cylinder, the
submarine cable in the cylinder is provided with two mutual assorted inner cylinders, a double components resin is arranged in the two inner cylinder, the outer surface of the cylinder is provided with an optic cable joint
package, the optic cable is connected with the optic cable joint
package through the cylinder, a double components resin is arranged in the optic cable joint
package, the invention has the advantages that: due to the setting of the airproof fixation piece, two fault ends of the
submarine cable is fixed, the
cutting of the
submarine cable in the joint position under an outside force action is avoided; the setting of the
electricity conductive drawbars ensures the electric communication between the jacket steel wire of the two
submarine cable fault ends; due to the setting of the optic cable joint package, the optic cable is connected with the optic cable joint package through the cylinder and ensures the electric communication of the optic cable; the setting of the double components resin plays the role of anti-
corrosion, waterproof, and airproof.
