Description
Przedmiotem wynalazku jest przy¬ gotowywanie srodka nasycajacego dla izolacji wlóknistej przewodników elek¬ trycznych, które przy podwójnej trwalo¬ sci pozostaja odpornemi na zmiany po¬ gody i zachowuja gietkosc.Niedawno zaproponowano do poko¬ stu, przeznaczonego do owijania prze¬ wodów elektrycznych, dodawac zwia¬ zki, wydzielajace tlen. Ten sposób posiada te ujemna strone, ze prze¬ wodniki wysychaja i zczasem pekaja.W przeciwienstwie do tego, wada ta zostaje uniknieta przez to, ze nietylko nie ulatwia sie utlenienie, lecz prze¬ ciwnie hamuje sie je przez dodanie do oleju srodków odtleniajacych (redukcyj¬ nych). Wskutek tego warstwa izolacyj¬ na pozostaje gietka i przelozenie (zalo¬ zenie na nowo) starego przewodnikai nie przedstawia zadnych trudnosci.Redukujace dzialanie pylu cynkowego na oleje jest juz znane, lecz zasadniczo dla innych celów. Stosowanie zas oleju, traktowanego pylem cynkowym, do na¬ sycania i owijania przewodów elektrycz¬ nych, jest czems nowem, jak i wogóle dodawanie redukujacych srodków do oleju lub pokostu. Nastepna zaleta go¬ towej masy polega na tern, ze przewod¬ nik przy malej srednicy posiada bar¬ dzo wielka zdolnosc izolacyjna i nad¬ zwyczajna odpornosc przeciwko przebi¬ janiu. Pozatem przewodniki sa nad¬ zwyczaj lekkie. Metoda zostaje zasto¬ sowana w taki sposób, ze sie miesza.pyl cynkowy z pokostem z oleju lnia¬ nego w odpowiednim stosunku. Nastep¬ nie owity lub opleciony drut zostaje na¬ sycony masa i wystawiony na powie¬ trze dla schniecia. Po wysuszeniu moz¬ na przeciagnac drut jeszcze przez to¬ piona cerezyne (wosk ziemny) lub pa¬ rafine. Uzywanie cerezyny i parafiny dla powlekania przewodnika nasyconego olejem lnianym jest juz znane. W da¬ nym jednak wypadku otrzymuje drut gladszy wyglad, przyczem doplyw po¬ wietrza do masy nasycajacej zostaje przerwany, i wskutek tego osiaga sie dalsze zahamowanie procesu utleniania.Wreszcie, przez to ulatwionem zostaje przeciaganie drutów. PLThe subject of the invention is the preparation of a impregnating agent for the fibrous insulation of electric conductors, which, with a double durability, remain resistant to weather changes and retain flexibility. Recently it has been proposed for a room intended for wrapping electric wires, adding a bonding Tears, giving off oxygen. The disadvantage of this method is that the conductors dry out and break over time. On the contrary, this disadvantage is avoided by not only not facilitating the oxidation but, on the contrary, inhibiting it by adding deoxidizing agents to the oil. May). As a result, the insulating layer remains pliable and the reposition (refitting) of the old conductor presents no difficulties. The reducing effect of zinc dust on oils is already known, but essentially for other purposes. The use of zinc dust treated oil to impregnate and wrap electrical cables is often new, as is the addition of reducing agents to the oil or varnish in general. A further advantage of the finished mass is that the conductor, with a small diameter, has a very great insulating capacity and an extraordinary puncture resistance. Moreover, the guides are extremely light. The method is applied in such a way that the zinc dust is mixed with the linseed oil varnish in a suitable ratio. The wrapped or braided wire is then saturated with the mass and exposed to the air to dry. After drying, the wire can still be pulled through melted ceresin (earth wax) or paraffin. The use of ceresin and paraffin to coat a linseed oil saturated conductor is already known. In this case, however, the wire becomes smoother, the air supply to the impregnating mass is interrupted, thereby further inhibiting the oxidation process. Finally, the pulling of the wires is facilitated thereby. PL
