PROCEDE DE FABRICATION DE FILS ELECTRIQUES ET PRODUITS EN RESULTANT.
La présente invention est relative aux fils conducteurs d'électricité et a pour objet un procédé de fabrication,qui donne aux fils un très grand coéfficient d'isolement et assure leur incombustibilité.Ce dernier avantage présente une grande importance d'une manière générale,il en est spécialement ainsi lorsque les fils doivent être utilisés pour la signalisation des chemins de fer et analogues.
Suivant l'invention,on enroule d'abord autour du conducteur nu du fil de verre ; fait alors traver- ser par le fil ainsi guipé un bain de vernis isolant et ignifuge.Ensuite on effectue un second guipage,après quoi on le vernit et ignifuge de nouveau.Avant que le vernis ne soit complètement sec,on recouvre le fil avantageusement de talc,afin de faciliter son passage dans les canalisations.
<Desc/Clms Page number 2>
Le second guipage peut être remplacé par un tressage autour du fil conducteur d'un fil d'amiante,de coton ou d'une fibre textile appropriée.
Grâce au double vernissage ignifuge subit par le fil, celui-ci est rendu totalement incombustible,si bien même que son exposition à la flamme n'influence nullement son isolement.

METHOD OF MANUFACTURING ELECTRIC WIRES AND RESULTING PRODUCTS.
The present invention relates to electrically conductive wires and relates to a manufacturing process, which gives the wires a very high insulation coefficient and ensures their incombustibility. This last advantage is of great importance in general, it This is especially so when the wires are to be used for railway signaling and the like.
According to the invention, it is first wound around the bare conductor of the glass wire; then passes through the wire thus wrapped a bath of insulating and fire-retardant varnish. Then a second wrapping is carried out, after which it is varnished and fire-retardant again. Before the varnish is completely dry, the wire is advantageously covered with talc, to facilitate its passage in the pipes.
<Desc / Clms Page number 2>
The second wrapping can be replaced by a braiding around the conducting thread of an asbestos thread, of cotton or of a suitable textile fiber.
Thanks to the fire-retardant double varnishing undergone by the wire, it is made completely incombustible, so that its exposure to the flame does not in any way influence its insulation.
