For the connection of mobile machines under extremely high mechanical loads, mainly in mining situations, e.g. for coal-cutting machines, free trailing applications, particularly suitable for extreme bending loads, high tensile stress and impact and crushing loads. The torsion and tensile-stress-resistant armour, in conjunction with the high flexibility of the cable, also allows the cable to be operated via guide pulleys or used as a reeling cable on Load-Haul-Dumpers (LHDs). The phase-concentric monitoring shield and the common-concentric earth conductor, in conjunction with appropriate monitoring equipment, make it possible to monitor the cable for insulation faults and damage resulting from external influences. The cable can be supplied with 2, 3 or 6 pilot cores.
