Problems solved by technology

However, the thermosetting rubber cables made of these materials using the usual vulcanization process have the following disadvantages: First, the production process is complicated and the environmental pollution is serious, such as carbon black pollution and carbon dioxide, sulfur dioxide and dust released by coal-fired boilers; The produced cable insulation and sheath have low mechanical strength and are not resistant to torsion, resulting in poor torsion resistance of soft power cables for wind power, which affects the service life of the cable

Abstract

The invention relates to an application of thermoplastic elastomer on soft power cable for wind power generation, which can greatly improve the property of soft power cables and simplify preparation technology. The thermoplastic elastomer comprises the following components in percentage by weight: 20-80% of EPDM, 5-50% of polyolefin resin, 2-20% of ethylene / vinyl acetate copolymer, 0.2-5% of phenolic resin, 0.2-5% of organic peroxide and the balance of accessory ingredient. The thermoplastic elastomer of the invention is applied to the soft power cable for wind power generation.

Description

Technical field: [0001] The invention relates to the application of thermoplastic rubber on flexible power cables for wind power generation. Background technique: [0002] As a non-polluting renewable green energy, wind energy has been paid more and more attention by people. In recent years, wind power has developed by leaps and bounds in the world. The power cables used in wind turbines are different from ordinary power cables. They need to withstand the torsion of frequent wind direction changes, and at the same time need to withstand the harsh climate where the wind farm is located, such as resistance to severe cold and salt spray from seawater. Therefore, the basic requirements for such power cables for wind power generation are: softness, twist resistance, low temperature resistance, and salt spray resistance. [0003] In the past, the commonly used flexible power cables were made of vulcanized rubber, such as ethylene propylene rubber, silicone rubber, etc. for the in...
