Claims (4)
1. Ljusbägsskydd att användas i anslutning till en ledare (1) i en sk. belagd friledning, vilken ledare är 5 försedd med ett tunt isoleringsskikt och är med ett spi-ralband (2) fast pä en isolator, vilket 1jusbägsskydd om-fattar dtminstone en skyddsdel (4) avsedd att mottaga brännverkan frän ljusbägens fotpunkt och anordnad i gal-vanisk kontakt med ledaren (1), och en parallellt med den 10 belagda ledaren vid dess upphängningspunkt placerad blank strömväg, kännetecknat därav, att spiralban-dets (2) resistans är förminskad i sädan grad att det kan fungera som en ljusbägen transporterande blank strömväg.
2. Ljusbägsskydd enligt patentkravet 1, k ä n -15 netecknat därav, att den blanka strömvägen utgörs av en electricitet ledande beläggning pä träden eller trä-darna som bildar spiralbandet (2).
3. Ljusb&gsskydd enligt patentkravet 1, kännetecknat därav, att den blanka strömvägen omfat- 20 tar en eller flera i spiralbandet (2) integrerade metallt-rädar.
4. Ljusbägsskydd enligt nägot av patentkraven 1-3, kännetecknat därav, att spiralbandet (2) är anordnat i galvanisk kontakt med skyddsdelen (4). » · I • ·
