Twin Core Solar Cable
Engineered for high-efficiency industrial solar systems, our Twin Core Solar PV Cable delivers unparalleled safety and durability. Certified to TUV EN 50618 (H1Z2Z2-K), it features tinned copper conductors and UV-resistant XLPO insulation for maximum power transmission in extreme environments (-40°C to +120°C). Ideal for commercial/utility solar projects requiring reliable DC power transfer.
Key Features:
✅ Double-Core Design: Simplified routing and reduced installation time.
✅ TUV-Certified: Guarantees compliance with European safety & performance standards.
✅ Weatherproof Shield: Resists extreme temperatures (-40°C to +120°C), UV radiation, and moisture.
✅ Fire-Retardant: Low-smoke, zero-halogen (LSZH) insulation reduces toxic emissions.
✅ High Conductivity: Tinned copper conductors for corrosion resistance and efficient power flow.
