Material Properties

  • Conductor Flexibility: Class 2 stranding balances durability and moderate bendability.

  • Insulation Durability: Resists abrasion, moisture, oils, and UV degradation (indoor use).

  • Electrical Safety: High dielectric strength (2.5kV AC test).

  • Thermal Stability: Maintains integrity at 70°C continuous load.

Application Scenarios

  • Power Distribution: Fixed wiring in switchboards, junction boxes, and control panels.

  • Lighting Systems: Circuit connections in commercial/residential buildings.

  • Industrial Equipment: Internal wiring for motors, transformers, and HVAC units.

  • Installation Methods:

    • Conduits, trunking, cable trays

    • Surface-mounted clips (protected areas)

    • Not Suitable: Direct burial, outdoor exposure, or wet locations.

Installation Notes

  1. Bending Radius:

    • ≤25mm OD: Min. 4×OD

    • 25mm OD: Min. 6×OD

  2. Ambient Temperature: ≥0°C during installation.

  3. Protection: Mandatory conduit/trunking for mechanical and environmental protection.

  4. Compliance: Install per IEC 60364/BS 7671 and local regulations.

⚠️ Critical Reminder: Non-sheathed design requires secondary containment. Unsuitable for dynamic/vibration-prone applications.
