Abstract

The utility model provides a variable frequency cable used for 690V vessel electric propulsion. The variable frequency cable comprises a cable core and a protective layer, wherein the cable core is round and formed by twisting three main insulating cores and three neutral insulating cores, and the main insulating cores and neutral insulating cores are mutually crossly arrayed and formed into a round cable core through filling. The main technical characteristics of the variable frequency cable lies in that each main insulating core consists of a main core conductor and an irradiation crosslinking polyethylene insulating layer, a semiconduction tape is wound outside the cable core, and the outer side of the semiconduction tape is provided with a warping tape consisting of a layer of flame retardant low-smoke halogen-free tape and two layers of polyester tapes; a shielding layer braided by tinned copper wires is arranged outside the polyester tapes of the warping tape, and a copper tape warping tape is arranged outside the shielding layer braided by the tinned copper wires; and a low-smoke halogen-free flame retardant over sheath is arranged outside the copper tape warping tape. The variable frequency cable has the advantages of good magnetic field shielding effect and low radiation and is beneficial to popularization and application.
