Embodiment 1

[0032] See figure 1 with figure 2 , The photoelectric composite cable for shore power in this embodiment includes a main core 1, a ground core conductor 2, a loop control core 3, an optical cable 4, an inner filling layer 5, a strengthening layer 6 and an outer sheath 7.

[0033] There are three main cores 1 , and the three main cores 1 have the same structure, including a conductor 11 , a first shielding layer 12 , an insulating layer 13 and a second shielding layer 14 . The conductor 11 is made of several tinned copper wires twisted, and the nominal cross section of the conductor 11 is 50mm 2 to 240mm 2 , this embodiment adopts 756 tinned copper wires with a diameter of 0.4mm twisted, and the nominal cross section of the conductor 11 is 95mm 2. Conductor 11 meets the requirements of GJB1916 Table 1-2. The first shielding layer 12 , the insulating layer 13 and the second shielding layer 14 are wrapped outside the conductor 11 by three-layer co-extrusion. The first shie...

Abstract

The invention discloses an optoelectronic composite cable for shore power. The optoelectronic composite cable comprises three main wire cores, a ground wire core conductor, a loop control wire core, an optical cable, an inner filling layer, a reinforcing layer and an outer sheath. The three main wire cores, the ground wire core conductor, the loop control wire core and the optical cable are stranded to form the cable. The ground wire core conductor, loop control wire core and optical cable are located in a gap outside the two adjacent main wire cores. The inner filling layer is extruded outside the three main wire cores, the ground core wire conductor, the loop control wire core and the optical cable. The reinforcing layer is disposed outside the inner filling layer. The outer sheath is extruded outside the reinforcing layer.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a photoelectric composite cable used in ship shore power systems. Background technique [0002] Ship power station refers to the device on the ship that converts mechanical energy into electrical energy and monitors, controls, measures, distributes and protects it. The ship power station is composed of a prime mover, a generator (combined into a generator set) and a switchboard. A generator set is a device that converts kinetic energy into electrical energy, which is controlled and distributed through a switchboard. The prime mover that drives the generator can be a diesel engine, a steam turbine or a gas turbine, and the corresponding generator set is called a diesel generator set, a steam turbine generator set or a gas turbine generator set. Diesel generator sets have high working efficiency, low fuel consumption, light weight, fast start-up, convenient opera...
