CDT Double-Twist Stranders
Strong new designed equipment based onto a proven technology, suitable for heavy productions. An external rotating capstan can be combined to produce Cl. 2 conductors up to 61-wires.
  • Single-bow design for reduced energy consumptions.
  • Stepless pitch control and adjustable winding tension.
  • Heavy compacting of round conductors and straight sectoral.
  • Special twisting pulleys and bows for quality Cl. 5 conductors and cables lay-up.
  • Precision traverse by ball nut screw mechanism driven by brushless motor.
  • Perfectly balanced clamping of the take-up reel thanks to a dual-moving pintles design.
CDT are multi-purpose stranding machines suitable to produce Cl. 2 conductors with heavy compacting, Cl. 5 flexible conductors at high speeds and cables lay-up. When combined with the external rotating capstan CHR1000 they represent an effective alternative to rigid-cage stranders for mass production of Cl. 2 conductors with large cross-section.
