Solar cable H1Z2Z2-K 1x4 red 180487701

Photovoltaic installation cable – reliability and safety

This red solar cable H1Z2Z2-K with a cross-section of 1x4 mm² is a key element of every photovoltaic installation, both domestic and larger systems. It ensures safe and efficient transmission of energy from the panels to the inverter, minimizing losses and guaranteeing long-term operation. By choosing the appropriate cable cross-section, the installer can optimize system performance – for most domestic installations, 4 mm² is sufficient, but for higher powers or distances, it is worth considering cross-sections of 6 mm² or more. Remember that energy losses in cables should not exceed 1%, otherwise a thicker cable must be used.

Construction and properties

This cable has been designed specifically with the requirements of solar installations in mind. Its construction is based on several key elements:

• Core: Made of flexible, tinned copper strands, which ensures good conductivity and corrosion resistance.
• Insulation: Made of cross-linked halogen-free plastic, which provides high electrical insulation and safety in the event of a fire – it limits the emission of toxic gases.
• Outer jacket: Also made of cross-linked halogen-free plastic, protecting against the effects of weather conditions, UV radiation and mechanical damage.

Thanks to this combination of materials, the cable is characterized by high durability, resistance to abrasion and cuts, and stability over a wide temperature range (from -40°C to +90°C, and briefly up to +120°C). It is also resistant to ozone, which is important in industrial environments or areas with high levels of pollution.

Application and compliance with standards

The H1Z2Z2-K cable meets the stringent European standards EN 50618 and PN-EN 60228:2007, which guarantees its safety and reliability. It can be used both indoors (e.g. in basements or attics) and outdoors – on roofs, facades or in ground-mounted solar power plants. It is ideal for creating connections between photovoltaic panels and the inverter. Additionally, it meets the requirements of IEC 60754-1 and IEC 60364-5-52 regarding low smoke emission and flammability of building materials (class Dca).
