Construction Details

  1. Conductor:

    • Highly flexible stranded copper (Class 5)

    • Cross-section: 1.5mm² per core (3 cores)

    • Conforms to IEC 60228 Class 5 flexibility requirements

  2. Insulation:

    • EPR rubber compound for each core

    • Color-coded per harmonized standards (Brown/Blue/G-Y)

    • Excellent heat and aging resistance

  3. Assembly:

    • Cores laid parallel without filler

  4. Sheath:

    • Heavy-duty chloroprene rubber (CR) outer jacket

    • Resistant to oils, chemicals, abrasion, and weathering

    • Nominal thickness: 1.5mm

    • Black color with surface ribbing for identification

Material Advantages

  • Extreme Flexibility: Maintains pliability in sub-zero temperatures (-25°C)

  • Weather/Oil Resistant: CR sheath withstands UV, ozone, and mineral oils

  • Abrasion Protection: 50% thicker sheath than standard PVC cables

  • Flame Retardant: Self-extinguishing per IEC 60332-1-2

  • High Temperature Resilience: EPR insulation withstands temporary overloads

  • Water Resistance: IP66 equivalent protection when properly terminated

  • Certified Safety: CE marked, compliant with CPR Euroclass Dca-s1b,d1,a1

Application Scenarios

Ideal for portable equipment in harsh environments:

  • Construction site distribution systems

  • Welding equipment and portable generators

  • Agricultural machinery and irrigation systems

  • Industrial tools and mobile workshop equipment

  • Stage lighting and entertainment systems

  • Shipyard and marine applications

  • Mining equipment and quarry operations

Engineering Selection Notes:

  1. Voltage Rating: Suitable for 450/750V systems (max 500V phase-phase)

  2. Temperature: Avoid continuous use >60°C ambient temperature

  3. Bending Radius: Minimum 6×OD during installation (approx. 45mm for 3G1.5)

  4. Installation:

    • Never install as fixed wiring

    • Use cable glands with compression seals

    • Avoid sharp edges and dynamic abrasion points

  5. Certification: Valid only when bearing H07RN-F 3G1.5 and ▼0274 markings
