Problems solved by technology

[0003] In the existing winding wire technology for offshore wind power stator blocks, the winding insulation structure includes the inner layer of grade 1 to grade 2 paint film and the outer layer of polyester glass sintering. The disadvantages are that the insulation electrical performance is poor in stability and the breakdown voltage is not high. The solvent evaporates during the manufacturing process, which is not conducive to environmental protection and operation health
Because the inner layer of the winding wire is made of enamelled copper flat wire, and the paint film is used as the main insulating material of the product, due to the limitation of the processing technology of the enameled flat wire and the limitation of the insulat

Example Embodiment

[0024] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0025] like figure 1 As shown, a winding wire for an offshore wind power stator block includes a conductor 10 and an insulating layer attached to the conductor 10, and the insulating layer includes a first insulating layer 11 and a second insulating layer that sequentially coat the conductor 10 from the inside to the outside. Layer 12, the first insulating layer 11 is composed of Teflon polyfluoroethylene propylene composite polyimide film wrapped on the conductor 10, and the second insulating layer 12 is composed of polyester and polyester wrapped on the first insulating layer 11. Made of fiberglass blend.

[0026] In this example, the nominal thickness of the first insulating layer 11 is 0.038 mm, wherein the nominal thickness of the Teflon polyfluoroethylene propylene film is 0.013 mm, and the nominal thickness of t

Abstract

The invention relates to a winding wire for an offshore wind power stator block and a preparation method thereof. The winding wire comprises a conductor and an insulating layer attached to the conductor, and the insulating layer comprises a first insulating layer and a second insulating layer which sequentially coat the conductor from inside to outside; wherein the first insulating layer is formedby a Teflon polyfluoroethylene propylene composite polyimide film wrapped on the conductor, and the second insulating layer is formed by polyester and glass mixed fibers wrapped on the first insulating layer. According to the winding wire for the offshore wind power stator block, the phenomenon that the sealing performance of a product is affected due to uneven bonding of the Teflon polyfluoroethylene propylene is avoided, meanwhile, the bonding performance of the Teflon polyfluoroethylene propylene after high-temperature treatment is higher, and therefore the sealing performance of an insulating layer is better; and the polyimide film is used as the main insulating layer, so that the electrical performance is more stable and reliable, the product is softer, the anti-knocking performanceis better, and the cable is more suitable for rear flat bending winding and bending forming.
