Application
For the connection of mobile electrical equipment in mines and tunnels. Suitable also for coal cutting machines,
particularly for extreme bending loads inside of steel or plastic track chains.
CABLE CONSTRUCTION
Power Cores
conductor:Tinned copper conductor DIN VDE 0295 class 5
Insulation:Based on 3Gl3-EPR rubber and semi rubber compound
CONTROL CORES+MONITORING PE CORE(S)
conductor:Tinned copper conductor DIN VDE 0295 class 5
Insulation:3Gl3 type EPR compound and semi conductive rubber compound
Cradle Separator:A shaped section of elastomeric material. Semi conductive, with control wire in the center.
