SOLAR PV CABLE UL Certified DC Double Insulated Photovoltaic Wire

1. Overview

High-Efficiency Solar Photovoltaic Cable
Engineered for solar energy systems, this UL 4703 & TUV-certified DC photovoltaic cable ensures maximum power transmission efficiency under extreme outdoor conditions. Designed for direct burial, UV exposure (-40°C to +120°C), and long-term durability in photovoltaic arrays, combiner boxes, and solar trackers.

2. Key Features

✅ Ultimate Weather Resistance

UV Stabilization: Cross-linked polyethylene (XLPE) insulation + halogen-free LSZH outer sheath, passing 3000+ hours QUV accelerated aging test (ASTM G154).
Temperature Range: -40°C to +120°C (IEC 60216-1 thermal endurance class 120).
✅ High Conductivity & Safety

Conductor: Class 5 fine-stranded tinned copper (EN 60228), reducing oxidation and ensuring 30% lower resistance than bare copper.
Double Insulation: XLPE inner layer + LSZH outer sheath, rated for 2000V DC (UL 4703 compliant).
✅ Flexible Installation

Bend radius ≥ 4×OD, IEC 62930 cold bend test (-40°C).
Flame-retardant (IEC 60332-1) and acid/alkali resistant (IEC 60811-2-1).

3.Applications

⚡ Solar panel interconnections (PV string wiring)
⚡ Ground-mounted solar farms & rooftop installations
⚡ Off-grid systems with MC4 connectors
⚡ Inverter-to-grid connections (DC side)

4.Certifications

UL 4703: Flame and sunlight resistance
IEC 62930: Photovoltaic system compliance
CPR EuroClass Cca-s1b,d1,a1: Fire safety for EU markets
