Abstract

A process of producing a conducting layer on the outer surface of a thermoplastic synthetic resin insulation layer comprises applying to the external surface of the resin a dispersion of a fine-grained powder wherein the liquid is such that it becomes permanently absorbed into the resin and so leaves the fine-grained powder to form at the external surface of the said conducting layer, wherein the absorption of the liquid increases the resistance to glow discharge and the destructive strength of the resin, and wherein the dielectric constant of the liquid is substantially equal to that of the resin. The particles may be of carbon black or graphite and the synthetic resin may be polyethylene. The liquid constitute 50-70% by weight of the dispersion and may be an aromatic hydrocarbon containing two benzene nuclei linked directly or through a carbon atom. Liquids specified are bisbenzyl toluene, dimethylisopropylebenzene, dodecylbenzene, a low molecular weight polymer of trifluoromonochloroethylene and hexachlorobutadiene. For insulations consisting of high-pressure polyethylene, paraffin oils may be used and for polyvinyl chloride insulation, fatty acid esters and benzoic acid esters are specified. Anti-ageing compounds such as amines or phenols may be added to the dispersion. The dispersion may be heated before application and may be applied to the hot surface of the insulating layer immediately after it has been applied. The dispersion may be applied as a spray or the insulating layer may be passed through a bath of dispersion which thereby may act as a cooling bath. The dispersion may be applied immediately the layer leaves the mouthpiece of an extrusion machine. In the apparatus shown, covered cable 5 leaves an extrusion machine (not shown) and the suspension is sprayed on from nozzle 4 and excess returns to vessel 1. Surplus dispersion still adhering to the cable is removed by the stripper 6 in the form of a foam sponge.
