Series resistance heating cables
Heating cables with series resistance should be used when the voltage has a high impact on on heating cable power. These are ideal for frost protection and temperature maintenance if the total lenght of the cable exeed 200 meters.
Max working temperature
up to 600V
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.
