    Sicherheitskabel.   



     Die Anwendung   der Elektrizität in Bergwerken und in Räumen, in denen explosive Gase vorhanden sind, wurde bisher   dadurch beeinträchtigt, dass   durch die bei Beschädigungen der Leitungen   entstehenden Kurzschlüsse   oder Stromunterbrechungen Funken erzeugt werden, 
 EMI1.1 
 
Solche Beschädigungen der Leitungen können sowohl durch Zerreissen derselben, wie auch durch   Quetschung, Drehung und   Schlag geschehen.

   Diese Gefahr tritt besonders dort ein. wo es sich um biegsame, lose   Leitungen handelt, wie   sie als Zuleitung für transportable Apparate, besonders auch für   Handlampen usw. verwendet werden.   
 EMI1.2 
 werdcn wird dadurch erreicht, dass zwischen   den Leitern eine sehr dünne Isolationsschicht sich     befindet, während die   Isolation nach aussen aus einem sehr dicken,   widerstandsfähigen, hoch-   elastischen Material besteht, welches durch die Wirkungen einer etwaigen Funkenbildung bei Berührung der Leiter nicht zerstört werden kann, und welches auch infolge seiner elastischen Eigenschaften bei Beanspruchung des Kabels auf Zerreissung die Bruchstelle im Innern noch luftdicht abschliesst. 



   Die innere Isolationsschicht muss. da das Kabel alle beim Gebrauch vorkommenden Biegungen ertragen soll, ohne dass eine   Beschädigung   eintritt, biegsam und geschmeidig, nicht   brüchig   sein, auch nicht bei niedrigen Temperaturen. 
 EMI1.3 
 standsfähigkeit umgeben ist, die ausserdem von einer imprägnierten   Garnumklöpplung   geschützt wird. 
 EMI1.4 
 filiert   Leiter verwenden kann,   zu dem Zwecke, die innere   Isolierschicht leichter zu durchschneiden.   als dies bei runden Drähten der Fall ist.

    Security cable.



     The use of electricity in mines and in rooms where explosive gases are present has so far been impaired by the fact that sparks are generated by short circuits or power interruptions caused by damage to the lines,
 EMI1.1
 
Such damage to the lines can be caused by tearing them, as well as by crushing, twisting and hitting them.

   This danger occurs especially there. where flexible, loose cables are involved, such as those used as supply lines for portable devices, especially for hand lamps, etc.
 EMI1.2
 is achieved in that there is a very thin insulation layer between the conductors, while the outside insulation consists of a very thick, resistant, highly elastic material, which cannot be destroyed by the effects of any spark formation when the conductors are touched, and which, due to its elastic properties, closes the breakage point on the inside still airtight when the cable is stressed.



   The inner insulation layer must. because the cable should be able to withstand all bends occurring during use without damage occurring, be flexible and pliable, not brittle, not even at low temperatures.
 EMI1.3
 stability is surrounded, which is also protected by an impregnated yarn braiding.
 EMI1.4
 filleted conductors can be used to make it easier to cut through the inner insulating layer. than is the case with round wires.
