Electric Connection
Backer offers two different types of heating cables with series resistance: Single core teflonized heating cable supplied with a resistances between 0,8 and 8000 ohm/km. Can be used for applications where temperatures up to 260°C can occur and were a voltage up to 600V is required Longline heating cables manage 5 km from one power sorce. Longline can be used for applications where temperatures up to 230°C can occur. The heating cable is offered in 1-pole or 3-pole designs and can give a constant wattage up to 60W/m The cables are EX-proof.
