Flexible cable for power supply or connections for large material handling or mining machines in open-pit mines where exposed to extremely high mechanical stresses, abrasion and tear usually during trailing operation. Cables classified according to EN 50575 (CPR).
Cable Design
Conductor : finely stranded class 5 (EN 60228, DIN VDE 0295) tinned, electrolytic copper
Protective-earth conductor : very finely stranded class 5 (EN 60228, DIN VDE 0295) tinned, electrolytic copper
Insulation : EPR compound with improved electrical and mechanical characteristics (DIN VDE 0207, Part 20)
Electrical field control : inner and outer layers of semiconductive rubber
Core identification : natural colouring with black semiconductive rubber and printed white digits 1 to 3
Core arrangement : three main conductors laid-up with protective-earth conductor split into 3 in the outer interstices
Reinforcement : extremely tear-resistant reinforcing tape preventing sheath movements and protecting from transverse and longitudinal stress
Inner and outer sheath : special 5GM5 compound (acc. to DIN VDE 0207, Part 21) with improved tear- and abrasion resistance characteristics, inner and outer sheath are inseparably bonded. Sheath colour black.
