H1Z2Z2-K

The H1Z2Z2-K cable is a highly flexible, halogen-free solar cable for modern photovoltaic systems. It meets the highest standards for safety, weather resistance, and electrical performance – for both indoor and outdoor use.

H1Z2Z2-K

For long-term use in demanding environments

The H1Z2Z2-K complies with DIN EN 50618 (VDE 0283-618) and is specifically designed for the cabling of photovoltaic systems. It can be installed permanently or used flexibly – indoors, outdoors, in industrial facilities, agricultural operations, or even in hazardous (explosive) areas. The cable is UV-, ozone- and water-resistant (AD7) and can be laid directly in the ground.

Construction and technical features

The finely stranded tinned copper conductor (class 5) is double protected by cross-linked insulation and a cross-linked outer sheath made of polyolefin copolymer – halogen-free, flame-retardant, and highly abrasion-resistant. The cable is designed for a maximum conductor temperature of 120 °C and remains reliably flexible even at -40 °C (fixed installation). Its low smoke emission and high resistance to mechanical and thermal stress ensure safe, long-term operation.
