The cable penetrating piece is used for connecting a main cable in the pipe area and a branch cable in the cargo hold area, and the watertight grade of the filler in the cable penetrating piece is not less than the maximum draught pressure of the container ship. Assuming that the maximum draft of the container ship is 22.3m/BL, the watertight grade of the filler in the cable penetration piece is 2.7bars, which is equivalent to bear 27m of water pressure, thereby meeting the maximum draft and not influencing the stability of the broken cabin.

The plurality of cable holders are respectively aligned with each of the cable penetrations and routed along their respective bays.

And the cable main bracket is internally provided with a main cable connected with initial electrical equipment in the cabin area, and each branch cable on the main cable penetrates through the corresponding cable penetrating piece from bottom to top and is laid along the cable bracket until the branch cable is connected with terminal electrical equipment in the cargo cabin area.

And the starting electrical equipment in the cabin area and the terminal electrical equipment in the cargo hold area are both a liquid level remote measuring system and a valve remote control system.

And the liquid level remote measuring system and the valve remote control system of the cargo compartment area are arranged at the bottom of the transverse compartment of the cargo compartment area.

The invention also provides a cable laying method from the cargo hold area of the container ship to the cargo hold area, which comprises the following steps:

and S1, determining the positions of the initial electrical equipment in the cabin area and the terminal electrical equipment in the cabin area.

And S2, determining the specifications of the cable main bracket and the cable bracket according to the specifications of the main cable and the branch cables thereof (including the number of the cables and the size of the cable section), and selecting the type of the cable penetration piece according to the maximum draught of the ship.

S3, arranging main cable brackets from the cabin area to the pipe area along the length direction of the ship, then installing a plurality of cable penetration pieces corresponding to the cross compartments in the cargo hold area on the top plate of the pipe area, and then arranging a plurality of cable brackets along each cross compartment of the cargo hold area.
