A method for producing an insulated electric wire of the present invention is a method for forming an insulating coating film on a surface of an electric wire by performing baking treatment after forming an insulating layer on the surface of the electric wire by an electrodeposition method using an insulating electrodeposition coating material containing a polymer. Pretreatment of evaporating a solvent in the insulating layer is performed before the baking treatment, and the pretreatment is performed by a near infrared ray heating furnace. In addition, a temperature of the pretreatment is lower than a temperature of the baking treatment.

A method of manufacturing a connector device suitable for making an inter or intra static electrical energy converter connection. The device includes at least two flat conductors and at least one insulating material. The said method includes: preparing each flat conductor individually; applying at least one coat of enamel varnish to each conductor, which is thinner than a desired final thickness; carrying out cross-linking of the enamel coating; and repeating the depositing of a layer of enameling resin and the cross-linking until the chosen thickness is reached. The varnish coated conductors of the connector device are assembled by using a template and connecting elements.

An insulation application assembly for applying insulation to a power line employs an open-ended enclosure to partly surround a segment of the power line. The assembly employs an insulation material conveying mechanism to move insulation material from insulation storage to the insulation material applicator connected to the interior surface of the open-ended enclosure.

A device (1) and a method for producing enameled wires, comprises an application device (3) for applying at least one enamel coating, a furnace (4) for solidifying the enamel coating and an exhaust gas purification device (7) for removing at least nitrogen oxides from an exhaust gas (9) of the furnace (4). The exhaust gas purification device (7) has a unit (13) for the selective catalytic reduction of nitrogen oxides in the exhaust gas (9) of the furnace and a feeding apparatus (11) for feeding a reducing agent, preferably an ammonia-containing compound, in particular a urea solution, into the exhaust gas (9) of the furnace (4). The feeding apparatus (11) has at least one outlet opening, which is designed in such a way that the reducing agent exits from the outlet opening substantially in the flow direction of the exhaust gas (9).

The invention relates to a field coil (18, 20), in particular for a satellite hall-effect plasma thruster, said field coil (18, 20) comprising a core (22) on which a conductor (24) is wound, characterized in that the conductor comprises an inorganic insulation cable (26) impregnated with a high-temperature-resistant silicone coating (32).

A method for manufacturing a terminal-equipped electric wire includes a step of crimping a first terminal to one end of an electric wire, a step of crimping a second terminal to the other end of the electric wire with a tubular seal member, a first waterproofing step of providing, at the one end of the electric wire, an anticorrosion member that covers an element wire bundle of the electric wire, and a second waterproofing step of providing, at the other end of the electric wire, a sealing member so as to fill gaps between conductive element wires of the element wire bundle in a tubular insulating sheath. The second waterproofing step is performed after the first waterproofing step is performed.
