CORDAFLEX SMK Reduced Earth 3+3x/3 Drum Reeling Cable | 0.6/1 kV VDE GOST-R

CORDAFLEX (SMK) drum reeling cable with reduced 3-way split earth section. Type (N)SHTOEU. 0.6/1 kV, rubber PCP, 30 N/mm², 240 m/min. VDE registered, GOST-R approved. High-capacity crane power.

CORDAFLEX (SMK) Reduced Earth 3+3×/3 Drum Reeling Cable

The CORDAFLEX (SMK) with reduced 3×/3 earth section is designed for gantry and container crane installations where maximum power conductor cross-section is required within the constraints of a fixed drum width and cable OD. By splitting the earth conductor into three equal sections distributed in the interstices between the phase cores, the design allows one or two cross-section steps larger phase conductors compared to equivalent full-earth cables.

All CORDAFLEX (SMK) design features are retained: PROTOLON EPR insulation, PROTOFIRM PCP double sheath, anti-torsion polyester braid, VDE registration, and GOST-R approval — with 30 N/mm² tensile load and 240 m/min travel speed.


Key Design Features

  • Type: (N)SHTOEU with 3-way split reduced earth (3×/3 configuration)
  • Phase conductors: 35 mm² to 300 mm² Class FS
  • Earth conductors: three equal sections in phase core interstices
  • PROTOLON EPR insulation (compound 3GI3)
  • PROTOFIRM PCP inner + outer sheath (yellow)
  • Anti-torsion polyester braid — vulcanized bond
  • Individual shielding on control/data cores: tinned Cu braid ≥60%/≥80%
  • Max tensile: 30 N/mm²; torsional: ±50°/m; speed: 240 m/min
