A method produces a cable. A sheath is applied to a product in strand form and the product in strand form is supplied, for this purpose, to an apparatus which has a bath containing a curable material. A build-up zone is formed in the bath, within which build-up zone the curable material is at least partially cured by an exposure source and through which the product in strand form is conveyed lengthwise in a conveying direction, so that cured material is arranged on the product in strand form and is conveyed out of the bath together with the product in strand form as a sheath on the product in strand form.

A process of making a cable having a conductor surrounded by at least one crosslinkable layer having a polymer composition. The polymer composition has (a) a polyolefin bearing hydrolysable silane groups and a silanol condensation catalyst compound.

Methods and systems for a dielectric material coated busbar are provided. In one example, a conductive material may be formed into a shape of a busbar and portions of the busbar may be selectively coated with a dielectric material which may be both electrically insulating and thermally conductive. The dielectric coated portions of the busbar may dissipate heat to a heat sink via a thermal interface material compressed on the busbar.

A coated electrical accessory includes a bare electrical accessory and a substantially inorganic and dried coating layer coating the bare electrical accessory. The coating layer includes a heat radiating agent and a binder. When the coated electrical accessory is tested in accordance with ANSI CI 19.4-2004 with an amount of imparted current, the coated electrical accessory exhibits an operating temperature that is less than an operating temperature of a bare electrical accessory tested in accordance with ANSI CI 19.4-2004 with the same amount of imparted current. Methods are also provided.

A production method of double-wire string lights, comprising the steps of: prepaying wires; annealing to optimize the flexibility of the wires; cooling and washing; making outer layer of the wires; removing the outer layers of both the positive and negative wires to expose the positive and negative wires and form the bulb welding positions; coating with tin; using an automatic bulb welding machine for welding of the positive wire bulb welding positions and the negative wire bulb welding positions corresponding to the positive poles and negative poles of the surface-mounted LED chips; wrapping the surface-mounted LED chips and the bulb welding positions with high-transmission epoxy resin and then putting them into a UV pre-solidification equipment with an extraman to solidify the epoxy resin in exposure to UV, demolding after solidification; the simple structure offers convenience and flexibility in use.

A curing material, having a solubility parameter of 9.4 or more, contains at least a chain transfer agent that contains a compound containing a polyether structure and two or more urethane bonds or two or more urea bonds in a molecule, and a metal-containing compound. A wire harness is manufactured by supplying the curing material to a conductor exposed portion of a wire bundle including a plurality of bundled insulated wires each having a conductor covered with a covering material made of an insulating body, the conductor exposed portion being formed by removing a part of the covering material of the wire bundle to expose the conductor inside; and curing the curing material by irradiating light in a state in which a surface of the curing material is covered with a protective member formed from a resin containing a plasticizer and having light transmissivity, thereby forming a waterproof portion.

A composite wire includes a metal inner core, an easily-passivated metal layer wrapping a surface of the metal inner core, and a self-adhesive resin layer wrapping a surface of the easily-passivated metal layer. An insulation layer of the composite wire is a metal passivation layer that is formed by the easily-passivated metal layer obtained after sintering treatment and oxidation. The preparation method is used for manufacturing the composite wire. The method for preparing a power inductor is used for preparing a new type of power inductor including the composite wire. The composite wire is high-temperature resistant and is easily wound. During winding, the easily-passivated metal layer is unlikely to fall off, thereby ensuring that the insulation layer formed by passivation of the easily-passivated metal layer has desirable weather resistance and voltage resistance.

A nanocable in which the thickness of a core including a wire of first conductor is reduced and a layer of second conductor containing carbon nanotube is introduced, thereby achieving a cable having an ultrafine wire diameter and preventing current intensity from decreasing due to an increase in resistance because of the ultrafine wire diameter. The nanocable is configured such that a polymer layer (an insulating layer) is interposed between the core including a wire of first conductor and the layer of second conductor, thus preventing current intensity from decreasing due to an increase in resistance attributable to the ultrafine wire diameter while ensuring a cable having an external diameter ranging from ones of m to hundreds of m and having a nano-sized core diameter, whereby the nanocable can be utilized in medical instruments such as endoscopic tools.
