PRODUCTION OF INSULATED ELECTRICAL CONDUCTORS

摘要

PRODUCTION OF INSULATED ELECTRICAL CONDUCTORS Method and apparatus for forming an insulating layer of substantially constant diameter on an electrical conductor. The layer is coated upon the conductor as a homogeneous mixture of fluid carrier and magnetically permeable particles and the coating operation takes place by passing the conductor upwardly through the fluid mixture and then upwardly and axially through a magnetic field. The field resists the flow of particles through it, thereby permitting a certain thickness of the material to pass through the field and coat the conductor. At least one annular magnet is used to create the field and when two or more magnets are used, these are axially in line with each other.
