Description

Technical Field

[0001] The utility model relates to the field of cables, and more specifically to a tensile-resistant and wear-resistant shore power cable. Background Art

[0002] Shore power cables are widely used in power, lighting, control, and communication systems on various ships, offshore oil platforms, and structures above water. Shore power cables are an indispensable component of a ship's electrical system, and their performance and quality are directly related to the ship's electrical safety and operational efficiency.

[0003] Shore power cables are not fixed in place. Instead, they connect to shore power sources or equipment while the ship is docked. Therefore, the shore power cables must be moved each time a connection is needed. To prevent damage caused by dragging the shore power cables on the ground, they are typically transported using transport carts. Traditional shore power cables lack tensile strength, which can easily damage or even break their internal structures during use, impacting the safety and stability of power transmission. Furthermore, if the cable's wear resistance is poor, the outer layer can easily wear out, damaging the cable's insulation and internal structure, leading to decreased electrical performance and even safety incidents.

[0006] Furthermore, there are four tensile ropes, which are distributed in a circular shape with equal intervals.

[0007] This allows the cable to withstand greater tension.

[0008] Furthermore, there are four cable cores, which are distributed in a ring-like shape with equal intervals.

[0011] Thereby effectively protecting the internal structure of the cable.

[0012] Furthermore, the outer shielding layer is an aluminum foil shielding layer, and the inner shielding layer is a copper wire braided shielding layer.

[0013] Thus the cable has better shielding performance.

[0014] Furthermore, the hook groove has rounded corners.

[0015] Thereby, the hook can be conveniently clamped in the hook slot.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The cable of the present application adopts a steel wire tensile rope and a stable supporting skeleton structure, so the cable can withstand a large tensile force and ensure stable operation in complex environments.

[0018] 2. The cable of the present application has a wear-resistant layer, so that the cable can effectively resist friction and wear in the external environment and extend its service life.

[0019] 3. The cable of the present application has a wear-resistant rubber ring with an annular hook groove for cooperating with the hook on the transport vehicle.
