Embodiment Construction

[0030] The present invention will be described in further detail below through examples, and the following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0031] Such as figure 1 As shown, a light variable frequency flexible cable for ships and offshore engineering platforms of the present invention includes a main insulated core 1, a neutral core 2, a shielding layer 3, an armor layer 4 and an outer sheath 5, and the main insulated core 1 is three and its section is tile-shaped at 120 degrees. The three main insulated cores 1 form a complete ring and are set outside the neutral core 2. The shielding layer 3, the armor layer 4 and the outer sheath 5 are from the inside to the outside. The outside is sheathed on the outside of the main insulated wire core 1 in turn. The three main insulated wire cores 1 are in the shape of 120° tiles, and a neutral wire core 2 is distributed in the center of the three mai...

Abstract

The invention discloses a light variable frequency flexible cable for ships and offshore platforms and a manufacturing method thereof. Its cross-section is in the shape of a 120-degree tile. The three main insulated wire cores form a complete ring and are sleeved on the outside of the neutral wire core. The shielding layer, armor layer and outer sheath are sequentially sleeved on the main insulated wire core from inside to outside. outside. The present invention uses a structure in which the tile-shaped main insulated wire core surrounds the outer side of the circular neutral wire core. There is no gap between such structures and the inside and both sides of the tile-shaped main insulated wire core are pressed against each other, and the outer side is covered. Covering, so that the four directions are completely restricted, the structure is stable, and it is not easy to cause position deviation, so that when the cable is bent and twisted, the stable symmetry of the cable can also be guaranteed.

Description

technical field [0001] The invention relates to a flexible cable and a manufacturing method thereof, in particular to a light frequency conversion flexible cable for ships and marine engineering platforms and a manufacturing method thereof, belonging to the field of cable manufacturing. Background technique [0002] With the development of energy saving in the shipbuilding and offshore engineering industries, variable frequency AC drives are widely used in fans, capstans, main propellers, rudder propeller drives and various special working conditions. Harmonics, electromagnetic interference, reflected wave voltage, and induced voltage of adjacent cables generated by the frequency conversion system will cause damage to the cable, shorten the service life of the cable, and affect electrical safety performance. The reliability of ships and offshore equipment is a very critical issue. Vibration, humidity and salt may cause damage to the mechanical and electrical components of ma...
