A process of applying a fluid containing one or more additives to a surface of a linear substrate in a linear compartment. The process includes passing the linear substrate through first and second seals of the linear compartment, contacting the linear substrate with the fluid within a chamber within the linear compartment while an exposure gap has a first length that is greater than zero, the contacting being conducted for a time with the fluid at a temperature. The linear compartment is dimensionally reconfigurable, optionally during an infusion process.

A single coated conductor for an overhead power transmission or distribution line is provided comprising one or more electrical conductors (400) and a first coating (401) provided on at least a portion of the one or more electrical conductors (400). The first coating (401) comprises: (i) an inorganic binder comprising an alkali metal silicate; (ii) a polymerisation agent comprising nanosilica (“nS”) or colloidal silica (SiO.sub.2); and (iii) a photocatalytic agent, wherein the photocatalytic agent comprises ≥70 wt % anatase titanium dioxide (TiO.sub.2) having an average particle size (“aps”)≤100 nm. The first coating (401) has an average thermal emissivity coefficient E≥0.90 across the infrared spectrum 2.5-30.0 μm and has an average solar reflectivity coefficient R≥0.90 and/or an average solar absorptivity coefficient A≤0.10 across the solar spectrum 0.3-2.5 μm.

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.

Provided are apparatuses for the processing of one or more components of a fluid into the surface of a linear substrate. The apparatuses include a processing barrel having a chamber defined therein as well as a linear substrate inlet and a linear substrate outlet. The processing barrel also includes a fluid inlet and a fluid outlet in fluid communication with the chamber. An exposure gap is defined between the linear substrate inlet and the linear substrate outlet. The chamber is dimensionally reconfigurable so that the exposure gap can have a length from zero to greater than zero.
