In the open-cast and underground mining bigger performances are demanded by the machines and processes, which means that nowadays also bigger machines are used. E. g., a bucket wheel excavator or a crawler excavator now operates with an installed capacity of more than 15 MW at a voltage of 35 kV. This requires that reliable cables are used for these specific applications.
For such movable machines, the Prysmian Group, Wuppertal/Germany, has developed special high flexible reeling cables which can withstand the extreme conditions in mining (Figures 1, 2). The flexible cables PROTOLON, PROTOMONT and TENAX have been used worldwide for decades and are developed continually.
