Problems solved by technology

Conventional torsion-resistant power cables for offshore wind power generation do not have high requirements for torsion resistance, and only need to meet the torsion angle of ±120° / m. However, with the further development of offshore wind power, the existing torsion-resistant power cables cannot meet the requirements of large offshore wind turbines. Large Angle Yaw Requirements

Abstract

The invention discloses a halogen-free low-smoke rubber-sheathed flexible cable for marine wind power generation and a preparation process thereof. The flexible cable comprises a copper conductor positioned at the center, an isolation belt layer is wound on the outer surface of the copper conductor, an ethylene-propylene rubber insulating layer coats the outer surface of the isolation belt layer,and a 110DEG C halogen-free low-smoke polyolefin rubber sheath layer coats the outer surface of the ethylene-propylene rubber insulating layer and is composed of EVM500HV, microcrystalline wax, DOS,white carbon black, aluminum hydroxide, elastomer Poe, antiager XH-3, DCP, trimethylolpropane trimethylacrylate TMPTMA, A-172, waterproof agent and high-wear-resistance carbon black N-330. The problems of long-time high carrying capacity, aging, special oil resistance and large torsional angle of the flexible cable are solved, and the flexible cable reaches international leading level and has highpractical value and popularization value.

Description

technical field [0001] The invention relates to a cable for ships, in particular to a halogen-free low-smoke rubber-sheathed flexible cable for offshore wind power generation. Background technique [0002] As a clean and renewable energy, wind energy has been paid attention to by many countries in the world in recent years. Because the development of offshore wind power does not occupy land land, and offshore wind energy resources are abundant and suitable for large-scale development, offshore wind power has become an inevitable trend in the future development of wind power. [0003] Compared with onshore wind farms, the marine environment in which offshore wind turbines are located is very complex and harsh, and they are subjected to a variety of random loads that vary with time and space, including wind, waves, currents, sea ice, and tides acting on the structure. threatened by earthquakes. Under such harsh environmental conditions, unfavorable factors such as environmen...
