Cable for photovoltaic installations Solarflex-X PV1-F 1x4 black, 2-standard, double insulation, elukabel 704226

Application and Resistance in Harsh Conditions

This cable is designed with the specific requirements of photovoltaic installations in mind, where safety and durability are paramount. Thanks to the double insulation made of polyolefin, the cable effectively protects against UV radiation, moisture, as well as aggressive chemicals and oils. This is not merely an aesthetic issue – such construction guarantees that the installation will last 25 years without loss of insulating properties, even in locations exposed to direct sunlight and rain.

It is worth noting the temperature range in which the cable can operate: from -40 °C to +90 °C. This means it will perform well both on freezing winter days and during summer heatwaves when module temperatures can rise significantly. During installation itself, the permissible ambient temperature ranges from -5 °C to 90 °C, facilitating work for installers in different seasons.

Construction and Ease of Installation

The key element is the conductor made of copper, classified as Class 5 (flexible stranded). This makes the cable extremely flexible and easy to install, even with tight spacing or when numerous bends are required within the inverter cabinet. The cross-section of 4 mm² allows for safe current transmission in DC circuits with a rated voltage of 1000 V (U) and 600 V (U0).

The cable features a uniform black sheath, which is the standard for DC lines in PV installations. The outer diameter is approximately 5.4 mm, making it a compact solution that does not excessively burden cable ducts or mounting brackets. The lack of shielding is not a limitation here – in typical photovoltaic installations, shielding is not required, and the absence of additional layers increases flexibility and facilitates final connections.

Summary of Key Features

Thanks to the combination of high mechanical resistance and installation flexibility, this cable forms a solid foundation for modern solar systems. It does not require specialized tools for cutting or joining – standard mounting accessories are sufficient for its proper installation and protection against mechanical damage during operation.

In summary, the most important features are:

• Intended for photovoltaic installations (DC current).
• Copper conductor with a cross-section of 4 mm² in flexibility class 5.
• Rated voltage 1000 V / 600 V ensuring safety for high-voltage circuits.
• Double polyolefin insulation resistant to UV radiation and weather conditions.
• Wide operating temperature range: from -40 °C to +90 °C.
• Compact outer diameter approx. 5.4 mm facilitating cable routing.
• Long service life of up to 25 years while maintaining insulating properties.
