Photovoltaic cable H1Z2Z2-K B2ca 4mm² Black 500m SOLB-4-BK-500

Photovoltaic installation cable – reliability and safety

This black photovoltaic cable with a cross-section of 4mm², supplied in a practical 500-meter roll, is a key element of every solar installation. The H1Z2Z2-K cable is designed for efficient and safe transmission of energy between photovoltaic panels, inverters and other PV system components, both in on-grid and off-grid installations. It will work well in both roof and ground systems.

Durability and safety for years

Made of high-quality materials, this cable is characterized by exceptional resistance to harsh environmental conditions – UV radiation, ozone, temperature changes and humidity. Tinned copper conductors for better conductivity and corrosion protection ensure long-term reliability. The cable construction has been tested for operation at temperatures up to +90°C (continuous) and +120°C for 20,000 hours, which guarantees its stability even under high loads. The minimum operating temperature is -40°C, allowing it to be used in various climates.

Flame retardancy class B2ca – protection of your investment

The cable meets the highest safety standards thanks to the B2ca flame retardancy class. This means that in the event of a fire, it does not spread flames and limits the release of toxic fumes – which is particularly important in photovoltaic installations located in residential or industrial buildings. By choosing a B2ca cable, you are investing in the safety of yourself and your loved ones.

Technical specifications for professionals

The cable has a rated voltage of 0.6/1kV AC and a working voltage of up to 1.5kV DC (compliant with EN 50618 standard). The insulation resistance is 1000 MΩ/km, ensuring minimal energy losses. The 50Hz test voltage is 3500V or 4000V (depending on the source), which confirms its high quality and reliability. The minimum bending radius is 4x the cable diameter, making installation easier even in tight spaces. The expected service life is as long as 25 years!
