Multi-core warp resistance medium voltage rubber jacketed flexible cable for wind power generation

Abstract

The invention discloses a multi-core warp resistance medium voltage rubber jacketed flexible cable for wind power generation. The flexible cable comprises a cable core and a star shaped bar inside the cable core. The cable core is formed in such a manner as three insulation cores are twisted in parallel inside the star shaped bar. The twisting direction of the core is identical to that of conductors. The core is coated with a first butyl rubber water layer; an inner protection sheath is wrapped around the first butyl rubber water layer through extrusion; a reinforcing aramid yarn is woven outside the inner protection sheath. The reinforcing aramid yarn is coated with a second butyl rubber water layer. Finally, an outer protection sheath is arranged through extrusion as the outermost layer of the cable. The uttermost center of the cable core is further provided with a reinforced aramid fiber rope. The introduction of a new structure into the cable enables the cable to possess a strong warp resisting ability. In comparison with the prior art, the service lifetime of cable can be extended so that the cable renewal cycle of a wind power generator is shortened. The cable is also energy-saving, possesses the feature of reducing emissions and plays an important role in saving resources.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a twist-resistant rubber-sheathed soft cable for multi-core medium-voltage wind power generation. Background technique [0002] In the 21st century, my country's economy has developed rapidly, industrialization and urbanization have accelerated, energy demand has grown rapidly, and the contradiction between energy supply and demand has become increasingly prominent. Increasing the diversified supply of energy and ensuring energy security have become important tasks for economic and social development, and the development and utilization of renewable energy has become an important part of the national energy development strategy. As one of the renewable energy sources, wind power generation has been highly valued in my country due to its great resource potential, low environmental pollution, sustainable utilization, and basically mature power generation technology and economic effi...
