[0002] A subsea traced cable, also known as an electric tracing tape, is a cable that can generate heat and is usually composed of a semiconductor heating material, a heat insulation material, parallel busbars, and an insulating layer. This cable is mainly used for pipeline heat preservation in ocean engineering, such as long-distance transportation of viscous oil and highly waxy oil at sea, to improve the pipeline heat preservation effect and avoid solidification inside the subsea pipeline or pressure increase.

[0003] The traditional cable connection seal uses a single-layer sealing method with a sealing gland. When the single-layer connection seal is used in deep water areas, water leakage may occur, resulting in a decrease in insulation or even zero insulation, causing the entire power supply system to trip and affecting the electric tracing effect.

A sealing ring is built into one end of the first sealing pipe, and each connection port is sleeved inside one end of a first sealing pipe through the sealing ring, and the other end of the first sealing pipe is sleeved outside the second sealing pipe.

[0007] An energizing piece is fixedly arranged at the middle position inside the communicating pipe body. Spring fixed ends are respectively fixedly connected to the inner top surface and the inner bottom surface of the communicating pipe body near the connection ports on both sides of the energizing piece, and a clamping block is connected to the spring movable end.

[0008] The energizing piece is connected to an indicator light arranged on the outer surface of the communicating pipe body.
