2.3 Key Parameters

Ⅲ. Applications

3.1 High-Voltage PV Systems

• Utility-Scale Solar Farms: Ideal for 2000V DC setups in 100kW+ projects, connecting panel strings to central inverters.

• Energy Storage Systems (ESS): Links batteries to inverters in large-scale storage arrays, handling high currents efficiently.

3.2 Industrial & Commercial Wiring

• Manufacturing Plants: Integrates solar power into industrial DC circuits, supporting heavy machinery and lighting.

• Off-Grid Remote Sites: Suited for desert or coastal installations where durability and high voltage are critical.

3.3 Installation Scenarios

• Conduit/Raceway: Use PVC conduit for outdoor UV protection; metal conduit for fire-rated areas.

• Aerial Routing: Lightweight design allows overhead installation with strain relief clamps.

Ⅳ. Certification & Compliance

• UL 4703: Certified for North American PV applications (includes temperature cycling tests).

• NEC 2023 (Article 690): Complies with high-voltage DC wiring codes.

• RoHS 2.0: Lead-free conductor, halogen-free XLPE insulation.

• TÜV EN 50618 (Optional): Available for European markets (1500V/2000V versions).

Ⅴ. Installation Guidelines

5.1 Termination

• Connectors: Use 10AWG crimp terminals rated for 2000V DC (e.g., Anderson Powerpole or high-voltage lugs).

• Sealing: Apply heat-shrink tubing with adhesive liner to prevent moisture ingress.

5.2 Routing

• Bend Radius: ≥4× cable diameter (19mm) to avoid insulation damage.

• Temperature Derating: At 50°C ambient, derate current to 35A (NEC Table 310.15).

5.3 Safety Notes

• Polarity Marking: Black sheath denotes negative (-) by convention; pair with red cables for positive (+).

• Grounding: Route green-insulated ground wires separately per NEC 250.118.

Ⅵ. Comparison with Double-Layer Cables

Ⅶ. Maintenance & Lifespan

• Inspection Frequency: Annually check for UV degradation (sheath cracking) and loose connections.

• Lifespan Expectancy:

• Protected environments: 15–20 years

• Unprotected outdoor: 8–10 years (with UV exposure)

• Troubleshooting: Use 1000V DC insulation tester; replace if readings <10MΩ.

Ⅷ. Packaging & Marking

• Standard Rolls: 100FT (30.48m), 500FT (152.4m), 1000FT (304.8m) on cardboard reels.

• Marking per FT:
  10/19 CU PV 2000V XLPE VW-1 ROHS UL4703 E345678

• Storage: Keep in dry, ventilated areas; avoid direct sunlight before installation.
