Aluminum Conductor PVC Insulated Nylon Sheathed Cable (450/750V) | UL AL-THHN/THWN-2 | IEC Equivalent

Product Overview

This Aluminum Conductor PVC Insulated Nylon Sheathed Cable (Commonly designated AL-THHNAL-THWN-2 in North America or structurally equivalent to H07V-N under IEC/HD standards) is engineered for reliable fixed electrical installations requiring cost-efficiency, mechanical durability, and chemical resistance. Designed for 450/750V voltage systems, it features an aluminum core, PVC insulation, and an abrasion-resistant nylon outer sheath, making it ideal for industrial, commercial, and harsh-environment applications.

Construction & Materials

  • Conductor: High-purity electrolytic aluminum (EC grade), compliant with Class 1/2 (solid/stranded) per IEC 60228 or ASTM B800.

  • Insulation: Thermoplastic PVC (Type T90 Nylon Jacketed per UL 83), providing excellent dielectric strength (>20 kV/mm) and chemical stability.

  • Outer Sheath: Extruded Nylon 6/66 (Polyamide), offering exceptional:

    • Abrasion resistance (>100 cycles, ASTM D1242)

    • Tensile strength (>70 MPa, ISO 527)

    • Resistance to oils, fuels, and solvents (UL 1277)

    • Low friction coefficient for easy conduit pulling.


Performance Advantages

  • Cost-Effective: Aluminum core reduces material costs vs. copper cables (Ideal for large-scale projects).

  • Mechanical Protection: Nylon sheath resists cuts, crushing, and wear in high-traffic areas.

  • Environmental Resilience: UV-resistant, moisture-tolerant (THWN-2 rating), and operates in -40°C to +90°C.

  • Safety Compliance: Flame-retardant (IEC 60332-1 / UL VW-1), RoHS/REACH compliant.

  • Easy Installation: Smooth nylon surface reduces pulling tension by up to 40%.


Application Scenarios

  • Industrial control panels & machinery wiring

  • Conduit/cable tray systems in manufacturing plants

  • HVAC systems, pumps, and motor connections

  • Commercial buildings (feeders/branch circuits per NEC Art. 310)

  • Outdoor lighting (wet locations, UV exposure)

  • Material handling equipment (conveyors, forklift chargers)


Engineering Selection Guide

  • Conductor Size Range: 14 AWG (2.5 mm²) to 4/0 AWG (120 mm²)

  • Standards Compliance:

    • UL/CSA: UL 83 (AL-THHN, AL-THWN-2), CSA C22.2 No. 75

    • IEC/EN: EN 50525-3-41 (H07V-N), IEC 60227

  • Derating Note: Aluminum conductors require 85% ampacity adjustment vs. copper (NEC Table 310.15(B)(16)).

  • Termination: Use AL-rated connectors (e.g., UL 486A-C) with anti-oxidant paste.


Packaging & Certifications

  • Supplied in 250m/500m/1000m drums or cut lengths.

  • Certified: UL Listed (E-number), CE Marked (IEC/EN), RoHS 3.

  • MOQ: 1,000 ft (305m). Custom labeling available.
