hb-digital Solar Cable H1Z2Z2-K 1×6mm² – TÜV-Certified PV Cable up to 1.5kV DC
General Information: The hb-digital Solar Cable H1Z2Z2-K 1×6mm² is a single-core photovoltaic cable with a cross-section of 6mm² for the DC wiring of solar systems. The cable is TÜV Rheinland certified according to EN 50618:2014.
Function: The cable carries direct current through a tinned copper conductor at a rated voltage of up to 1.5kV DC. The cross-linked insulation and sheath protect the cable permanently against weather and environmental influences.
Applications: The cable is intended for the wiring of solar modules and photovoltaic systems.
Material: The conductor is made of tinned copper, the insulation and sheath of XLPO. The material is halogen-free and low-smoke as well as resistant to UV, ozone, oil and chemicals.
Technical Details: The outer diameter is 6.3mm, the maximum conductor resistance is 3.39Ω/km (20°C). The cable is designed for ambient temperatures of -40...+90°C; the maximum conductor temperature is 120°C, and up to 250°C for 5s in case of a short circuit. It was tested with AC 6.5kV (50Hz, 5min).
Conclusion: A TÜV-certified, weather-resistant 6mm² solar cable for reliable DC wiring up to 1.5kV.

FAQ
Can I install the solar cable outdoors?
- Yes, the cable is resistant to UV and ozone (EN 50289-4-17) and designed for ambient temperatures of -40...+90°C – making it suitable for typical outdoor installation on solar modules.
Which system voltage is the cable suitable for?
- The rated voltage is 1.5kV DC (Uo/U 1/1kV AC; 1.5kV DC according to the certificate). The cable was tested with AC 6.5kV (50Hz, 5min).
What bending radius do I need to observe during installation?
- The minimum bending radius is 6 times the cable diameter (6×D). With an outer diameter of 6.3mm, this corresponds to approximately 38mm.
