I. Product Overview
The single-layer black 2000V PV wire is a high-voltage photovoltaic cable designed for demanding renewable energy systems. With a rated voltage of 2000V DC, this wire features a single insulation layer made of cross-linked polyethylene (XLPE) or equivalent materials, ensuring reliable performance in high-voltage applications. The black sheath offers enhanced UV resistance and outdoor durability, making it suitable for long-term exposure in harsh environmental conditions.
II. Key Features
2.1 High-Voltage Capability
2000V DC Rating: Specifically engineered to withstand high-voltage transmission in large-scale solar farms, energy storage systems, and industrial PV setups.
Low Voltage Drop: Optimized conductor design (typically tinned copper) minimizes resistance, ensuring efficient power transfer even over extended distances.
2.2 Single-Layer Insulation Design
XLPE Insulation: The single-layer construction uses cross-linked polyethylene for superior electrical insulation, thermal stability (-40°C to +90°C), and mechanical strength.
Thin yet Robust: Balances insulation thickness with flexibility for easy routing in tight spaces or complex installations.
2.3 Outdoor Durability
UV & Weather Resistance: Black sheath contains inorganic UV stabilizers to prevent cracking after prolonged sunlight exposure (tested for 1000+ hours of xenon arc irradiation).
Abrasion & Chemical Resistance: Withstands moisture, ozone, and mild chemical exposure, suitable for coastal, industrial, or high-humidity environments.

IV. Applications
Large-Scale Solar Farms: High-voltage DC wiring between arrays and central inverters in 100kW+ systems.
Energy Storage Systems (ESS): Connections between batteries, inverters, and grid tie points in utility-scale storage projects.
Industrial PV Installations: Wiring in factories, warehouses, or campuses with high-power solar setups.
Off-Grid & Remote Projects: Durable enough for remote locations with extreme weather conditions.
V. Installation & Compliance
5.1 Key Guidelines
Bend Radius: Maintain ≥4× cable diameter to avoid insulation damage (e.g., 24 mm for 10AWG).
Termination: Use high-voltage rated connectors (e.g., MC4-EVO) and ensure crimping tools match conductor size.
Grounding: Comply with local codes (e.g., NEC 690 for North America) for proper grounding of non-current-carrying components.
5.2 International Standards
UL 4703: Mandatory for North American PV applications, covering voltage testing and environmental durability.
TÜV EN 50618: Required for European markets, specifying 25-year service life and halogen-free construction.
