It is used for connection of mobile machines with very high mechanical load, especially in mines for coal cutting and loading machines as well as for supplying appliances and devices and auxiliary electrical circuits. Concentric phase monitoring screen and overall concentric earth conductor facilitate in connection with a suitable monitoring equipment monitoring of the cable from standpoint of insulation faults and damages that are caused by external effects.
Cable Design
Power Cores
Conductor: Tinned copper conductor DIN VDE 0295 class 5.
Insulation: Based on 3GI3 – EPR rubber and semi conductive rubber compound
CONTROL CORES + MONITORING PE CORE(S)
Conductor: Tinned copper conductor DIN VDE 0295 class 5.
Insulation: 3GI3 type EPR compound and semi conductive rubber compound.
Lay Up: Three power cores laid-up, with double concentric control cores and monitoring core in the outer interstices. If there are 3 control cores, the monitoring core is concentrically wrapped over insulation of control cores
Inner Sheath: GM1b type EPR compound
Screen / Armour: Flexible – pliable armour in helix of tinned copper and galvanised steel wires
Outer Sheath: Heavy duty elastomer 5GM5 type rubber compound. Yellow or Red.
