Cable insulation cross-linking apparatus with catenary and rectilinear cross-linking tubes

Abstract From the Canadian patent

Apparatus for the continuous cross-linking or vulcanizing of material on a conductor comprising a tube with a vulcanizing section in the shape of a catenary arc with the convex portion facing downwardly and with its ends at substantially the same level and a rectilinear cooling section extending upwardly and with its axis tangent to the axis of the catenary arc at the end of the vulcanizing section which adjoins the cooling section. Hot non-aqueous liquid is, circulated in the vulcanizing section and an inert cooling gas under pressure is circulated in the cooling section the liquid, being exposed to the gas where the sections meet. Inert gas also contacts the liquid at the end of the …
