TEBAOFLEX Dredging Cable -3E is a medium-voltage submersible trailing cable for dredger power supply and other demanding marine applications. The cable is designed for dynamic service where the cable may operate in water, move along the seabed and experience abrasion, tensile loading and repeated handling.
The Dredging Cable -3E range covers rated voltages from 3.6/6 kV to 12/20 kV. Its three power cores and three tinned copper earth conductors support applications that require a robust, screened power cable with redundant earth-conductor configuration.
Dredging Cable -3E Configuration
The “-3E” designation identifies a construction with three earth conductors. These earth conductors are distributed in the interstices of the cable construction and provide a redundant earthing arrangement for specified dredging and marine power systems. Confirm the applicable project standard and grounding requirement before selection.
Construction and Materials
- Power conductors: extra-fine stranded tinned copper, Class 5 in accordance with VDE 0295 / IEC 60228.
- Insulation: EPR rubber, 3GI3 type, in accordance with DIN VDE 0207-20.
- Earth conductors: three tinned copper earth conductors distributed between the power cores.
- Screen: tinned copper wire braid for the screened cable construction.
- Inner sheath and filler: rubber and textile/polyester components selected for the cable assembly.
- Outer sheath: black CM chlorinated polyethylene rubber compound, 5GM3 type.

Selection Guidance
When specifying a Dredging Cable -3E, provide the required voltage, conductor size, power demand, operating water conditions, installation length, movement pattern, bend radius and tensile-load requirements. These details help determine the appropriate cable construction for the dredger system and its operating environment.
