Abstract
The invention discloses an electrical cable for a high-carrying-capacity wind turbine generating set. An ethylene propylene rubber insulating layer is prepared from the following components: ethylene-propylene-diene-terpolymer rubber Kep510, microcrystalline wax, paraffin oil 2280, antimonous oxide, titanium dioxide, white carbon black, zinc oxide, nano-flame-retardant reinforcing agent JP150, 4-8 parts of elastomer particles, adhesive, 1-3 parts of dicumyl peroxide DCP and 0.8-2 parts of tri-methylol propane tri-methacrylate TMPTMA, wherein the elastomer particles are prepared from the following components: polypropylene, styrene-isoprene-styrene segmented copolymer SIS, glass fibers, glycerol tripalmitate and cyclohexane oxide. The high-carrying-capacity anti-torsion power cable can be used for solving the problem that the service life of a 5MW offshore wind turbine generation power anti-torsion cable is reduced due to long-term high carrying capacity, bending fatigue, aging and the like, and can remarkably improve the heat resistance of a material.
Description
technical field [0001] The invention relates to a torsion-resistant and fixed power transmission cable for a generator stator inside a fan, in particular to a high-capacity torsion-resistant cable. Background technique [0002] Wind energy, as a clean and renewable new energy source, has been widely concerned by countries all over the world. Wind energy is inexhaustible, and wind power is clean energy, which can reduce the consumption of traditional petrochemical energy and reduce CO emissions. [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 environmental corrosion, marine organism adhesion, foundation soil erosion and foundation dy...
