An electrical conductor insulated with at least one layer of fibrous material and having free-flowing mica devoid of binder disposed about the layer of fibrous material.
A method for providing an electrical conductor insulated with at least one layer of fibrous material and having free-flowing powdered mica devoid of binder disposed about the conductor, said method comprising the steps of:
- passing the conductor through a fluidized bed of powdered mica;
- and then encompassing the mica coated conductor with the fibrous material.
A method for providing an electrical conductor insulated with at least one layer of fibrous material and having free-flowing powdered mica devoid of binder disposed about the conductor, said method comprising the steps of:
- passing both the conductor and the fibrous material through a fluidized bed of the powdered mica;
- and then encompassing the mica coated conductor with the mica bearing fibrous material.
A method for providing an electrical conductor insulated with at least one layer of fibrous material and having free-flowing powdered mica about the conductor, said method comprising the steps of:
- encompassing the conductor with the fibrous material;
- and then passing the fibrous covered conductor through a fluidized bed of the powdered mica devoid of binder.
A method for providing an electrical conductor insulated with at least one layer of fibrous material and having free-flowing powdered mica devoid of binder disposed about the conductor, said method including the steps of:
- electrostatically depositing the powdered mica on the conductor, and then encompassing the conductor with the fibrous material.
