Abstract

The invention discloses a cable used for wind turbine generators. The cable comprises a cable core and a sheath layer used for coating the external side of the cable core; the sheath layer comprises, by weight, 2 to 4 parts of an anti-oxidant, 3 to 5 parts of isobutyltriethoxysilane, 8 to 12 parts of a plasticizer, 0.8 to 1.4 parts of hexakis(methoxymethyl)melamine, 0.4 to 1 part of ethoxylated trimethylolpropane triacrylate, 2 to 3.6 parts of di(tert-butylperoxy)phthalate, 55 to 65 parts of ethylene-propylene-diene monomer rubber, 40 to 60 parts of polyvinyl chloride, 20 to 30 parts of polyurethane, 60 to 80 parts of a composite filler, 1 to 2 parts of calcium stearate, 1.2 to 1.6 parts of barium stearate, and 1 to 3 parts of zinc naphthenate. The thermal stability of the cable is excellent; mechanical properties are excellent; aging resistance at extreme environment is extremely excellent; safety performance is high; and self life is long.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable for a wind turbine generator. Background technique [0002] Judging from the growth of global wind power generation in the past two years, wind turbine generators may grow at a rate of more than 50% in the next few years. These conditions show that there is a space for vigorous development and promotion of wind power generation, and it is matched with wind power projects. There is a huge market demand for special cable sheathing materials used. Wind power generation projects are carried out in the open air, and the service life of the cable sheath material is required to be very long. This requires extremely high thermal stability, aging resistance and mechanical properties of the cable material for wind turbine generators in extreme environments. Ordinary The cable has poor crack resistance, low safety performance and short service life cycle. Contents of the invention...
