Abstract
The utility model relates to a refractory composite insulated copper strand winding wire, which is formed by a conductor 1, a conductor insulating layer 2 and a composite insulating layer 3. The conductor insulating layer 2 is lapped on the conductor 1 to form an insulated conductor. A plurality of insulated conductors are twisted together and are pressed into a circular insulated conductor. The composite insulating layer 3 is lapped on the outer layer of the circular insulated conductor. The conductor 1 is of an annealed round copper single wire. The conductor insulating layer 2 is made of a refractory F-grade polyester film in an overlapping and lapping way. The composite insulating layer 3 is formed by an inner layer and an outer layer, wherein the inner layer is lapped with a refractory F-grade polyester film and the outer layer is lapped with alkali-free glass tapes. Through changing the material and the structure of the conductor, the utility model has the advantages that the volume of the device and the energy consumption are reduced, the voltage resistance and the operating stability of the winding wire are improved, and the service life of the device is prolonged. The utility model provides a novel product for the conducting wire and cable manufacturing field.
