(N)SHT11Y PUR Vertical Reeling Cable is a 0.6/1kV low-voltage cable engineered for vertical reeling duties on mobile harbour cranes and spreader basket systems. It combines exceptionally fine-stranded copper conductors, a self-supporting aramid element, braid reinforcement, and a black polyurethane outer sheath to address repeated movement, tensile loading, and harsh port environments.
TEBAOFLEX supplies special cables for demanding crane and port applications. Share the operating height, reeling arrangement, travel speed, and required control or data elements to confirm the appropriate construction.
Why Choose (N)SHT11Y for Vertical Reeling
- Self-supporting design: aramid reinforcement supports suspended vertical cable lengths.
- High dynamic durability: polyester braid reinforcement and torsion protection support repeated reeling cycles.
- Harsh-environment resistance: the black polyurethane sheath is specified as UV-, oil-, ozone-, and water-resistant.
- System integration: constructions can combine power conductors with control or data elements such as CAN-BUS pairs.
