Application

For the connection of electrical equipment large material handling machines such as excavators, cranes,

dumpers in mining and tunneling applications in combination of power and data transmission. The flexible cable

design allows for movement of the equipment during operation. Suitable also as flex MV reeling cable and also

for festoon systems.

CABLE CONSTRUCTION

conductor：Electrolytic stranded tinned copper wire DIN VDE 0295 Class 5

Insulation:3Gl3 type EPR compound

Electrical Field Control:Inner and Outer semiconductive layer of semiconductive rubber

Protective-Earth conductor:Tinned Copper conductor with semiconductive layer

Optical Fiber:Fibre core diameter of fiber 9μm, 625μm or 50μm; Diameter over cladding 125μm; diameter over

coating 250 μm; designs up to 24 fibers available.

Fiber coading:Color coding of the fibers and buffering tube for identification of the fiber type.

Fiber covering:Hollow core with filling compound,basic material ETFE

Arrangement of Fiber cores:Six cores in one layer and specially laid-up around the central support element

Lay Up:Three main conductors laid-up with two control cores and fiber optic element in the outer interstice

Inner Sheath:GM1b Type EPR compound

Reinforcement:Embedded braid made of anti torsion synthetic threads

Outer Sheath:5GM5 Type elastomer compound. Red
