Abstract

The invention discloses a medium-voltage torsion-resistant power cable for a wind generating set, and an insulating material thereof, wherein the insulating material comprises, by weight, 40-50 partsof ethylene propylene diene monomer, 1-3 parts of microcrystalline wax, 3-6 parts of paraffin oil, 5-12 parts of antimony trioxide, 1.3-3.7 parts of titanium dioxide, 1.6-3.4 parts of nanometer zinc oxide, 40-50 parts of calcined kaolin, 0.6-1.4 parts of a coupling agent, 1-2 parts of an anti-aging agent, 1.6-2.5 parts of a vulcanizing agent, and 0.8-1.6 parts of a vulcanizing aid. According to the invention, the high-temperature-resistant ethylene propylene rubber insulating material can tolerate 105 DEG C at most; and with the applications of the medium-voltage torsion-resistant power cablein the insulating of the anti-torsion power cable of an 8 MW offshore wind generating set, various power transmission and use performances of the high-current-carrying-capacity torsion-resistant cableof the offshore wind generating set in a normal working environment (the working temperature of -40 DEG C to 105 DEG C) are met, and the problem of service life reducing caused by the long-term highcurrent carrying capacity, bending fatigue, aging and the like of the torsion-resistant power cable of the 8MW offshore wind generating set is solved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a medium-voltage torsion-resistant power cable insulation material for a wind-driven generator set, and a medium-voltage torsion-resistant power cable for a wind-driven generator set using the insulating material. Background technique [0002] Compared with land wind farms, offshore wind farms are located in a very complex and harsh marine environment, bearing a variety of random loads that vary with time and space, including wind, waves, currents, sea ice, and tides that act on the structure. , and is also threatened by earthquake action. Under such harsh environmental conditions, unfavorable factors such as environmental corrosion, marine organism adhesion, foundation soil erosion and foundation dynamic softening, material aging, component defects and mechanical damage, fatigue and damage accumulation of crack propagation will cause damage to offshore wind turbine...
