- Cross-Linked Polyethylene (XLPE) is a thermoset insulation offering superior heat resistance (≥125°C), excellent chemical durability, and lower dielectric losses compared to PVC; preferred for engine bays, battery, and high-voltage applications.
- 2. What does 'Class 5/6' copper conductor mean?
- Classes 5 and 6 (per IEC 60228) denote flexible and extra-flexible stranded copper conductors, enabling tight bending radii and vibration resistance essential in vehicle harnesses.
- 3. What is a wiring loom?
- A wiring loom is a precisely grouped bundle of wires, cables, and connectors arranged for robust routing in vehicles or machinery, minimizing EMI (electromagnetic interference) and simplifying installation/servicing.
- 4. Why is RoHS compliance important?
- RoHS (Restriction of Hazardous Substances) compliance ensures wires are free from harmful lead, cadmium, and other toxic substances—crucial for automotive environmental and safety standards.
- 5. What are basket trays and their role?
- Basket trays are open metallic cable management trays enabling superior airflow and easy inspection/access for large-scale industrial wire installations in petrochemical and plant environments.
- 6. What's the meaning of 'VW-1, FT1/FT2' flame ratings?
- VW-1 is a UL wire flame test; FT1/FT2 are CSA flame propagation standards—all denote high flame retardance, essential for automotive and industrial safety.
- 7. Difference between tinned copper and bare copper in battery cable?
