Heavy duty rubber cable for control and power supplies. For festoon applications with mechanical tensile stress compared to dynamic stress. Different structures:
Conductor Flexible stranded, plain copper acc. DIN EN / IEC 60228 class 5
Insulation Elastomeric hard grade ethylene-propylene rubber compound better than IEC 60502-1
Inner sheath (not for single core versions) Special synthetic rubber compound for a max. operating temperature at conductor of 90 °C.
Outer sheath Heavy duty chlorinated rubber compound 5GM5 acc. DIN VDE 0207 part 21
