FAQ

• How does the 7x19 construction impact the cable's performance in high-flex applications?

  The 7x19 architecture, comprising 133 individual wires, offers a superior bend radius compared to standard configurations. This intricate braiding disperses mechanical stress evenly across the core, significantly reducing metal fatigue. This makes it exceptionally reliable for continuous-flexing mechanisms like automated doors, material handling conveyors, and robotic assemblies where rigid cables would quickly fail.

• What specific environmental factors dictate the choice between PE and PU coatings?

  Polyethylene (PE) is highly recommended for outdoor or industrial environments involving severe chemical exposure and freezing temperatures down to -40°C, as it resists cracking under thermal stress. Conversely, Polyurethane (PU) is the optimal selection for applications requiring extreme abrasion resistance and strict food-grade compliance, particularly in environments exposed to industrial oils or frequent physical scraping.

• Can the polymer jacket withstand prolonged exposure to direct sunlight without degrading?

  Yes, specifically when opting for our Polypropylene (PP) or UV-stabilized PVC coatings. These materials are formulated with advanced ultraviolet inhibitors that prevent the polymer chains from breaking down. This ensures the jacket remains flexible, vibrant, and structurally intact during years of outdoor architectural, construction, or marine deployment.

• How is the minimum breaking strength calculated when customizing the cable diameter?

  Breaking strength increases exponentially with the cross-sectional area of the steel core. For instance, while a 2.5mm core provides 4,410N of breaking force, scaling up to a 20mm core yields an immense 157,000N. Our engineering team assists in calculating the precise diameter required based on your specific dynamic and static load parameters, ensuring absolute safety compliance.

• What protocols are in place to ensure the integrity of custom end-fitting assemblies?

  All custom terminations are applied using precision hydraulic swaging equipment to ensure a flawless cold-weld between the fitting and the steel core. We strip the coating only at the exact insertion point to maintain maximum environmental protection along the cable length. Furthermore, each assembly batch undergoes rigorous pull-testing to verify it meets or exceeds the specified tensile ratings before dispatch.
