FLEXTRACE long heating cables and belts®

Long serial heating cables and belts were designed for the heating of long segments supplied from one spot. They are designated primarily for the heating of rails and railways, but can also be used for heating long pipelines, e.g. in tunnels and mines.

Increased expenses are always connected to setting up supply points for long heating routes. Therefore long heating cables and belts bring along financial savings. 

They are produced single-, double- or triple-core. Heating cables and belts are powered in single-phase, between two phases or three-phase. They consist of serial resistance conductors, flurinepolymer and silicone insulation and are further equipped with a stainless steel braiding for mechanical and electrical protection. 

These heating cables are manufactured based on the customer´s assignment in the required length, output and supply voltage.

C1FS/I – C2FS/I – R3FS/I – long heating cables and belts


A single-core heating cable, especially designed for heating concrete tracks for VAL subways (automatic without an engineer). Can be placed into a copper pipe.


A double-core heating cable, especially designed for heating metal tracks and rails for VAL subways. Can be inserted into composite U forms and attached to the rails by stainless steel clamps.


A triple-core heating cable used for heating very long segments, where a three-phase supply is available, e.g. in tunnels and mines.
