Ⅲ. Applications
3.1 Ideal Use Cases
High-Voltage PV Systems: 2000V DC setups in utility-scale solar farms (100kW+)
Energy Storage Systems (ESS): Battery to inverter connections in large-scale storage projects
Industrial Wiring: High-voltage DC circuits in manufacturing plants with solar integration
Off-Grid & Remote Installations: Desert or coastal areas requiring durable, high-voltage cabling
3.2 Installation Scenarios
Conduit/Raceway: Recommended for outdoor runs (PVC conduit for UV protection)
Direct Burial: Not suitable (single-layer XLPE lacks mechanical protection); use with steel conduit
Aerial Installation: Lightweight design allows overhead routing with strain relief clamps
Ⅳ. Certification & Compliance
UL 4703: Certified for North American PV applications (includes temperature cycling and impact tests)
NEC 2023 (Article 690): Compliant with high-voltage DC wiring requirements
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 custom high-voltage lugs)
Sealing: Apply heat-shrink tubing with adhesive liner for moisture protection
5.2 Routing
Bend Radius: ≥4× cable diameter (19mm for 10AWG) to avoid insulation damage
Temperature Derating: At 50°C ambient, derate current to 35A (consult NEC Table 310.15)
5.3 Safety Precautions
Polarity Marking: Black sheath denotes negative (-) by convention; pair with red cables for positive (+)
Grounding: Route green-insulated ground wire separately, per NEC 250.118
Ⅵ. Comparison with Double-Layer Cables
Feature | Single-Layer XLPE (2000V) | Double-Layer (XLPE+TPE, 2000V) |
Structure | Single insulation layer | Insulation + protective sheath |
Abrasion Resistance | Moderate (needs conduit) | High (suitable for direct burial) |
Cost per FT | (0.8–)1.2 (10AWG) | (1.1–)1.5 (10AWG, +30% premium) |
Ideal Environment | Protected outdoor/indoor | Unprotected, harsh conditions |
Ⅶ. Maintenance & Lifespan
Inspection Frequency: Annually for UV degradation (check for sheath cracking)
Lifespan Expectancy:
Protected environments: 15–20 years
Unprotected outdoor (with UV exposure): 8–10 years
Troubleshooting: Use insulation resistance tester (1000V DC) to check for degradation (reading <10MΩ indicates replacement needed)
Ⅷ. Packaging & Marking
Standard Rolls: 100FT (30.48m), 500FT (152.4m), 1000FT (304.8m) on cardboard reels
Marking per FT:
ES CABLE 10/19 CU PV 2000V XLPE VW-1 ROHS UL4703 E345678
Storage: Keep in dry, ventilated areas; avoid prolonged exposure to sunlight before installation
This 10AWG single-layer XLPE PV cable balances high-voltage performance with cost-effectiveness for large-scale renewable energy projects. Always verify installation codes (e.g., NEC, local electrical standards) and consult the manufacturer for specific application support.
