Abstract

The invention discloses a 66kV wind-power high-voltage twisted cable and a production process thereof. The cable includes: a saddle-shaped support filling layer located at the center of the cable andprovided with three arc-shaped notches and having a surface coated with graphite powder; three main wire cores disposed in the three arc-shaped notches of the filling layer and having a surface coatedwith graphite powder; three grounding cells each arranged between two main wire cores and supported by the filling layer, and having a surface coated with graphite powder; a semi-conductive inner protection Layer, a fiber silk braided layer and an outer sheath which are arranged in order outside the three main wire cores. The filling layer of the invention has the arc-shaped notches, engaged withthe main cores, which not only strengthens the cable's tensile and torsion resistance, but also achieves compact structure, a small installation space, and a large twisting pitch.

Description

technical field [0001] The invention relates to a cable, in particular to a 66kV wind power high-voltage twisted cable and a production process thereof. Background technique [0002] At present, the world is keen on sustainable renewable new energy, among which wind power plays a pivotal role. The driving force for the development of wind power technology in the future mainly comes from the booming construction of offshore wind farms, and this development trend is irreversible. Offshore wind turbines will gradually develop into large-scale units above 10MW, and the supporting foundation will change from fixed to floating. The scale of offshore wind farms will also continue to develop towards large scale. With the continuous growth of offshore wind power unit capacity, 33kV as the voltage level of the submarine cable in the field has gradually become a bottleneck restricting the design of the submarine cable system. Therefore, some European offshore wind farms took the lea...
