Abstract

The invention discloses an ultrahigh pressure cross linked polyethylene insulated flexible direct-current optical fiber composite submarine cable and relates to a direct-current cable. The ultrahigh pressure cross linked polyethylene insulated flexible direct-current optical fiber composite submarine cable is particularly used in large-power remote submarine power transmission in a flexible direct-current power consumption system of the vacuum control switch (VCS) current-switching technology and grid-tied connection among new energy alternating current systems of aperiodic operating wind power generation, tidal power generation and the like. The ultrahigh pressure cross linked polyethylene insulated flexible direct-current optical fiber composite submarine cable comprises direct-current cables, an optical fiber unit, a grounding feeder, filling strips, a main armor layer and an outer protective layer, wherein the two direct-current cables are respectively arranged on the left side and the right side, the optical fiber unit is arranged above the middle of the two direct-current cables, the grounding feeder is arranged under the middle portion of the two direct-current cables, and the cable is formed in a flat-supporting non-stranding mode; cable forming gaps are filled through arc-shaped filling strips; the direct-current cables, the optical fiber unit and the grounding feeder form the cable and then are armored through the main armor layer, the outer protectively layer is arranged on the surface of the main armor layer, anti-corrosion insulating glue is coated on each layer of polypropylene rope, and high-strength self-adhesive tapes are twisted outside the anti-corrosion insulating glue.

Description

technical field [0001] The ultra-high voltage cross-linked polyethylene insulated flexible direct current optical fiber composite submarine cable of the present invention relates to a direct current cable, especially for high-power long-distance submarine power transmission in the flexible direct current transmission system of VCS commutation technology, and aperiodically operated wind power Grid connection between new energy AC systems such as power generation and tidal power generation. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, the state vigorously develops and utilizes renewable clean energy and optimizes the energy structure. Compared with high-voltage AC transmission, DC transmission has the advantages of low line cost, small loss, long transmission distance, high system stability, small short-circuit current, and can realize AC back-to-back connection and phased construction and capacity exp...
