Low-temperature-resisting twisting soft cable for wind power generation

Abstract

The invention discloses a low-temperature-resisting twisting soft cable for wind power generation, which comprises a cable core; the cable core is formed by twisting multiple insulation wire cores; agap of the cable core is filled with a heat insulation wool, and the cable core is externally coated with a butyl glue water layer; the butyl glue water layer is externally wrapped with a cold-resisting internal sheath; the internal sheath is externally woven with an armor layer of a non-magnetic steel wire and a non-magnetic steel band metal structure; the armor layer is externally wrapped withan elastic buffer layer, and the elastic buffer layer is externally coated with a polyurethane heat insulation pipe; the cold-resisting internal sheath is formed by the mixture of a main sheath material and a secondary sheath material. The low-temperature-resisting twisting soft cable has fireproof, waterproof, windproof, sunproof, mildew proof, cold-resisting, aging-resisting, wind pressure resisting, and other performances; the cable has the advantages of high intensity, impact resistance, environment aging prestress crack resistance, corrosive resistance, low temperature resistance, and others.

Description

technical field [0001] The invention belongs to the field of power cables, in particular to a cold-resistant twisted flexible cable for 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 efficiency close to conventional energy...

Problems solved by technology

[0005] 1. This type of cable needs to be twisted for a long time. In the prior art, the cable is prone to bulges due to long-term twisting because there is no internally strengthened and stable structure;

[0006] 2. Due to the weight of this type of cable, and the long-term use of the cable at a height difference of 20 meters, and the use of the cable under the action of continuous torsional force, the cable joint will be easily broken due to the concentration of acceptance. thus affecting the use of
