摘要

Method of manufacturing non-combustible coating for electrical conductors based on plastic materials characterized in that prepared a mixture formed by polyvinyl chloride chloro-rubber cellulose acetate alkyl and phenolic resins with a plasticizer and addiction where appropriate and as a talc asbestos filler and all this in the proportions required by the type of conductor to be protected and once the aforementioned mixture is mixed to achieve its absolute uniformity according to the means usually employed in the plastics industry, the conductors to be protected are arranged in such a way that force them to pass through said mixture in pasty state to form on them separately an initial initial cover continuing then to undergo an individual drawing that is independent for each conductor to whose output the ones that have to form each cable are grouped to return to pass through the aforementioned doughy mixture volvi the wire is then drawn to the diameter that the cable must ultimately have undergoing a heating polymerization after which it is subjected to a cooling by artificial means.
