This TUV Rheinland approved H1Z2Z2-K twin core solar cable — designated 2×6 mm², rated 1500V DC and 0.6/1 kV AC — is a premium dual-voltage rated PV cable that satisfies both DC string wiring requirements and AC application compatibility in AC-coupled and hybrid solar-battery systems. The dual voltage rating (1500V DC / 0.6/1 kV AC) provides maximum application flexibility for system designers working across different inverter topologies and AC-coupled storage installations.
Both 6 mm² conductors are individually insulated with the H1Z2Z2-K compound (two layers of cross-linked halogen-free polyolefin), giving the cable the full H1Z2Z2-K designation — not merely a XLPO single-layer construction. This two-layer insulation system provides enhanced mechanical protection and superior resistance to chemical attack compared to single-insulation XLPO cables, making it suitable for direct burial alongside the AC-rated 0.6/1 kV designation. TUV Rheinland approved.

The H1 designates halogen-free material; Z2 insulation and Z2 sheath both denote cross-linked XLPO compounds — the two Z2 designations confirm two separate cross-linked layers, not a single XLPO layer. This construction improves resistance to mechanical damage, thermal aging, and chemical attack over the 25-year system life compared to cables using only a single XLPO layer with an XLPE outer cover.
