Embodiment Construction

[0026] Such as figure 1 As shown, a marine shore connection cable includes a cable core composed of multiple insulated wire cores, the cable core is extruded with a chlorinated polyethylene inner sheath 4, and the inner sheath 4 is wrapped with an aramid yarn braid layer in turn 5 and chlorinated polyethylene outer sheath 6;

[0027] In the insulated wire core, the conductor 1 is wrapped with an isolation tape 3, and the covering rate of the wrapping is 20-25%;

[0028] The isolation belt 3 is wrapped with an ethylene-propylene rubber insulating layer 2, and the thickness of the insulating layer 2 is 1.8-2.4 mm;

[0029] The thickness of the inner sheath 4 is 2.5-3 mm, the weaving density of the aramid yarn braided layer 5 is not less than 85%, and the thickness of the outer sheath 6 is 3.5-5.5 mm.

[0030] The number of insulated wire cores is three.

[0031] A chlorinated polyethylene inner sheath 4 is arranged outside the cable core by means of extruded extrusion.

Abstract

A marine shore connection cable, including a cable core composed of multiple insulated wire cores, the cable core is extruded with a chlorinated polyethylene inner sheath, and the inner sheath is sequentially wrapped with aramid yarn braiding layer and chlorinated polyethylene Outer sheath; in the insulated wire core, the conductor is wrapped with an isolation tape, and the covering rate of the wrap is 20-25%; the isolation tape is wrapped with an ethylene-propylene rubber insulating layer, and the thickness of the insulating layer is 1.8-2.4 mm; the inner sheath The thickness of the sheath is 2.5-3 mm, the weaving density of the aramid yarn braiding layer is not less than 85%, and the thickness of the outer sheath is 3.5-5.5 mm. The marine shore connection cable provided by the present invention can solve the problem of short service life of the existing cable, easy to cause power supply failure, and high replacement cost. Excellent, lightweight and comprehensive performance.

Description

technical field [0001] The invention relates to the field of cables, in particular to a marine shore connection cable. Background technique [0002] The shore connection power system is powered by manually dragging the shore connection cable from the ship to the shore and manually connecting it to the shore power distribution box. When the ship leaves the port, the cable is also manually wound. At present, there is no cable that fully meets the requirements of shore power supply, and YCW type cables, CEFR or CEPJR marine cables are usually used. However, these cables have obvious disadvantages, such as short service life, easy to cause power failure, and high replacement costs. [0003] Disadvantages / deficiencies of existing technologies: [0004] The long-term water immersion insulation resistance of YCW cables is low, and the withstand voltage is poor, which is not consistent with the wet and humid working environment of ports and wharfs; at the same time, a large cross-...
