Loop Feeder Cable to BS6346

Application and Description :

Loop Feeder Cable is used to connect traffic lights to the central control management system. The cables come in armoured, for direct burial, or unarmoured for applications where additional mechanical protection has been afforded by other means such as ducting. The Loop feeder cables are supplied in a highly visible orange for easy location of buried services. These cables are also suitable for use in small power, lighting or control circuits.
