Cable harnesses: Protection and insulation
Politubes produces a wide range of multilayer tubes and endcaps designed to:
1. Protect and insulate thermal protectors - thermistors in electric motor cable harnesses;
2. Hold together and protect lead-out wires from damage.
The choice of film to use for spiral wound tubes and endcaps for these applications depends on the thermal class of the motor, starting from class B up to class H.
As spiral wound tubes and endcaps are multilayer, different films can be added to a single tube or endcap, to combine their thermal and mechanical properties in a single product.
