FAQ

Navigating the technical specifications of multi-material cables requires precise information. Below, we address the most critical inquiries from engineering and procurement professionals to ensure you make the most informed sourcing decision.

• Which coating material is optimal for continuous outdoor exposure?
  For environments subjected to intense sunlight and weather fluctuations, PP (Polypropylene) or PE (Polyethylene) coatings are highly recommended. These materials possess superior UV resistance and moisture-repelling properties, preventing the jacket from becoming brittle or degrading over time, making them perfect for architectural railings and agricultural supports.

• How does the PU coating benefit dynamic mechanical systems?
  PU (Polyurethane) offers exceptional elasticity and extreme abrasion resistance. When used in systems requiring continuous movement over pulleys—such as fitness equipment or automated machinery—the PU jacket absorbs friction, operates silently, and resists wear significantly better than standard PVC, drastically extending the replacement cycle.

• What are the specific requirements for customized production runs?
  We offer deep customization to align with your project needs. For precise cut-to-length services, the minimum order quantity is set at 1 ton. If you require custom corporate logo printing or specific color-coding directly on the cable jacket, the minimum requirement is 10 kilometers of continuous production.

• Can this cable maintain integrity in extreme temperature zones?
  Absolutely. The thermal tolerance is dictated by the specific polymer jacket selected. For extreme cold, our PE-coated cables remain flexible and crack-resistant down to -40°C. Conversely, for high-heat industrial zones, the PU-coated variants maintain their structural and chemical stability in temperatures reaching up to +80°C.

• Does the product comply with industrial chemical resistance standards?
  Yes, our specialized coated cables are engineered to meet rigorous international safety and performance benchmarks. Specifically, they comply with the EN 60811-404 standard for mineral oil resistance, ensuring the protective jacket will not deteriorate when exposed to harsh industrial lubricants, hydraulic fluids, and processing chemicals.
