H1Z2Z2-K (EN 50618)
H1Z2Z2-K halogen-free solar cables are specifically engineered for high-performance direct current (DC) power transmission in photovoltaic (PV) systems. With a voltage rating of up to 1.5 kV DC, these cables offer industry-leading resistance to UV radiation, ozone, and extreme weather conditions.
Featuring flexible tinned copper conductors and cross-linked halogen-free insulation, our H1Z2Z2-K solar cables ensure a service life of over 25 years. Ideal for both indoor and outdoor solar installations, they provide maximum safety and reliability in harsh environmental temperatures.
Applications
- Photovoltaic (PV) power generation systems
- Solar panel to inverter connections
- String and array connections
- Rooftop and ground-mounted solar installations
- Indoor and outdoor PV installations
- DC circuits in renewable energy systems
H1Z2Z2-K cables are specifically developed for continuous operation in demanding
environmental conditions commonly found in photovoltaic applications.
Cable Construction
- Conductor: Fine-stranded tinned copper conductor
- Insulation: Halogen free cross-linked compound
- Core Identification: Red or Black
