TRATOS MTO®-Z

Used as power supply connection cable for mobile equipment in underground mining applications, such as coal shearer, tunnel driving machines and scoops (LHDs). (Z) Coal cutter cables are designed for free trailing operation and due to their special construction may be trailed for considerable distances behind the machine during operation.

The conductor is finely stranded copper conductor, tinned in class5 refer to DIN VDE 0295. The protective-earth conductor is steel/Cu stranded braid between the inner and the outer sheath. Control core is double-concentric control/monitoring conductor elements in the outer interstice.

The insulation of TRATOS MTO with basic material EPR with compound type 3GI3 refer to DIN VDE 0207 part20. Electrical field control with an outer semiconductive layer of semiconductive cold-strippable rubber.

The core arrangement is in three main cores laid-up, with double-concentric control/monitoring conductor elements in the outer interstice. Length of lay approx.6xD.The inner sheath is vulcanized rubber inner sheath with basic material EPR type GM1B. The reinforced braid is steel/copper wires in a vulcanized bond between inner and outer sheath. The outer sheath from TRATOS MTO is basically PCP in the compound type 5GM5. The colour of the outer sheath is yellow. The cores can be identified by colours in black, blue, brown and control cores in blue. The marking includes the year of manufacturing; VDE; TRATOS MTO-Z; NSSHCGEÖU; the number of cores; cross-section.

The standard is DIN VDE 0250, part 812.
