One aspect is a method for producing a plurality of wire elements, including providing a metal wire, coating the metal wire with a first layer to obtain a first coated wire, subjecting the first coated wire to a first quality control process, marking any first defects identified in the first quality control process, coating the first coated wire with a further layer to obtain a further coated wire, and cutting the further coated wire to obtain a plurality of wire elements. Prior to cutting the further coated wire to obtain the plurality of wire elements, a first length of the first coated wire is less than 10% longer than a further length of the further coated wire.

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 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.

An insulated electric wire includes a linear conductor and one or more of insulating layers formed on an outer peripheral surface of the conductor. In the insulated electric wire, at least one of the one or more of insulating layers has a plurality of pores, outer shells are disposed on peripheries of the pores, and each of the outer shells has a plurality of projections on an outer surface thereof.

To provide an electric wire and coil covered with a cured product of a heat- or photo-curable fluorinated polymer and having high insulating properties and high productivity. An electric wire comprising a conductor wire and a covering layer covering the outer periphery of the conductor wire, wherein the covering layer is made of a cured product of a curable composition comprising a fluorinated polymer containing at least three functional groups represented by the following formula (F):

R.sup.f1COZ.sup.1(F)

(in the formula (F), R.sup.f1 is a single bond, a fluoroalkylene group, or a fluoroalkylene group with at least two carbon atoms having an etheric oxygen atom between carbon-carbon atoms, Z.sup.1 is NR.sup.1NR.sup.2H, NR.sup.3OR.sup.4 or OR.sup.5, and R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are each independently a hydrogen atom or an alkyl group.)

A conductive portion of a circuit body is formed by performing spraying on a surface of a resin casing. For spraying of the conductive portion, a cold spray method in which metal powder and inert gas are sprayed to an object is used. A circuit component is mounted on the conductive portion. Each terminal portion of the conductive portion is provided with a connector for connection with an external circuit body. An insulating resin is laminated on a surface of the conductive portion. The circuit body is directly formed on the surface of the resin casing by a series of processes described above.

Provided are apparatuses for the infusion of one or more additives into the surface of a linear substrate. The apparatuses include a processing barrel having an infusion chamber defined therein as well as a linear substrate inlet and a linear substrate outlet. The processing barrel also includes an infusion fluid inlet and an infusion solution outlet in fluid communication with the infusion chamber. The infusion chamber is dimensionally reconfigurable, optionally during an infusion process.

The present invention relates to a surface modified overhead conductor with a coating that allows the conductor to operate at lower temperatures. The coating contains about 5% to about 30% of an inorganic adhesive, about 45% to about 92% of a filler, about 2% to about 20% of one or more emissivity agents, and about 1% to about 5% of a stabilizer.
