A device and method for sealing the end of cable outer sheath

Abstract

The invention belongs to the technical field of cable outer sheath end part sealing devices, in particular to a device for sealing the end part of a cable outer sheath. The device comprises a sealingcore (4) and a sealing pressing sleeve (5). The sealing core (4) comprises a sealing core connecting base (4-11) and a sealing core sealing section (4-12). The sealing core sealing section (4-12) is consolidated on the sealing core connecting base (4-11) to be integrally formed. The sealing pressing sleeve (5) has a hollow structure, and the sealing core (4) sleeves on the cable core (3). The sealing core sealing section (4-12) is located in the end part of the cable outer sheath (2). The sealing pressing sleeve (5) passes through the cable core (3) to sleeve on the outer side of the end partof the cable outer sheath and be fixedly connected with the sealing core. The device is a sealing connection device used for sealing the end part of the non-polar cable outer sheath and the reliability of the connection and the sealing of the end part of the non-polar sheath cable can be solved and the cable is enabled to be used in the deep sea for a long time.

Description

technical field [0001] The invention belongs to the technical field of cable outer sheath end sealing equipment, in particular to a device and method for sealing the end of a cable outer sheath, in particular to an outer sheath cable end of HDPE non-polar material Sealing device for use in deep sea. Background technique [0002] The outer sheath of the optical cable or cable can be differentiated between polar and non-polar. For the outer sheath of polar material, the end of the optical cable or cable can be sealed by vulcanization, potting or filling with glue. However, for non-polar The outer sheath made of polar material cannot seal the end of the cable or optical cable sheath by the above-mentioned conventional methods, especially for optical cables or cables used in deep sea for a long time.

[0002] The outer sheath of the optical cable or cable can be differentiated between polar and non-polar. For the outer sheath of polar material, the end of the optical cable or cable can be sealed by vulcanization, potting or filling with glue. However, for non-polar The outer sheath of polar material cannot seal the end of the cable or optical cable sheath by the conventional methods mentioned above, especially for optical cables or cables used in deep sea for a long time

[0003] The center of the steel wire armored cable is a photoelectric hybrid cable. Because the sheath of the photoelectric hybrid cable is HDPE, which is a non-polar material, when it is used in deep seawater, it cannot be installed reliably through the conventional vulcanization potting method or stuffing box method. ground seal
