EN 50618 H1Z2Z2-K Solar Cable 1500V
The EN 50618 H1Z2Z2-K Solar Cable 1500V is a high-performance photovoltaic DC cable designed for solar power systems. It is used for cabling between solar modules and as an extension cable between PV module strings and DC/AC inverters. This solar cable is suitable for rooftop solar systems, ground-mounted solar farms, off-grid PV systems, and other outdoor photovoltaic installations.
This H1Z2Z2-K solar cable uses a fine wire tinned copper conductor according to BS EN 50618 Class 5. The insulation and sheath are made from UV-resistant, cross-linkable, halogen-free, flame-retardant compound, helping the cable maintain stable performance in harsh outdoor environments. With excellent resistance to weathering, ozone, abrasion, and mechanical impact, it is a reliable cable solution for long-term solar DC power transmission.
