Heron Twin Solar Cable | 4mm² 6mm² 10mm² Twin Core PV Wire | TÜV Certified H1Z2Z2-K DC Cable for PV Systems
Heron’s Twin Solar Cable is the ultimate solution for professional solar installers. By integrating both positive and negative DC lines into a single, easy-to-separate parallel structure, we help you reduce cable management complexity and labor costs on-site.
Built to the same rigorous TÜV & EN 50618 standards as our single-core wires, this "Twin-Pack" delivers uncompromising 25-year reliability in a more efficient format.
The Twin Advantage
Integrated Design: Two cores (Red & Black) housed in a parallel UV-stabilized jacket. Pull once, install twice.
Rapid Polarity Identification: Clear color-coded internal insulation ensures zero mistakes when connecting strings to inverters or combiner boxes.
Clean Separation: Our specialized extrusion process allows the two cables to be separated manually without any jagged edges or damage to the outer sheath.
Space Saving: Ideal for tidy routing in cable trays, conduits, and roof-mounted systems where space is at a premium.
Core Technical Features
99.9% Tinned Annealed Copper: Maximize conductivity and eliminate corrosion, even in high-humidity or coastal salt-spray environments.
XLPO Double Insulation: Electron-beam cross-linked material provides superior resistance to UV, Ozone, and extreme thermal cycling (-40°C to +120°C max conductor temp).
H1Z2Z2-K / PV1-F Compliant: Engineered to meet the latest global standards for DC photovoltaic power systems.
Flame Retardant & Halogen-Free: Low Smoke Zero Halogen (LSZH) properties for maximum safety in residential and commercial rooftops.
