Cable for photovoltaic installations Solarflex-X PV1-F 1x4 blue, 2-standard, double insulation, Elukabel 705776

Application in Photovoltaic Installations

The Solarflex-X PV1-F cable with a 4 mm² cross-section in blue is a specialized cable dedicated to photovoltaic systems, where resistance to varying weather conditions is crucial. Its blue outer sheath, made of polyolefin, distinguishes it from standard black cables, facilitating identification of the neutral or grounding conductor in complex electrical circuits. This enables installers to carry out installation more quickly and safely, eliminating the risk of errors when connecting modules.

The cable features high flexibility, resulting from the use of a copper conductor of flexibility class 5 (stranded). Such construction allows for easy routing of cabling even in hard-to-reach places, e.g., behind module frames or in compact distribution boxes, without the need for additional bending tools.

Resistance to Environmental Conditions and Safety

The main advantage of this cable is its ability to operate in extreme temperatures. The range from -40°C to +90°C ensures that the cable maintains its mechanical and electrical properties both during freezing winter days and hot summer months when roof temperatures can rise significantly. Polyolefin insulation and outer sheath provide resistance to UV radiation, moisture, and other atmospheric factors, resulting in a long service life of the installation without the need for frequent inspections or replacements.

It is worth noting the rated voltage of 600/1000 V, which allows for safe operation in high-voltage DC circuits characteristic of PV installations. The 4 mm² cross-section represents an optimal choice for most standard photovoltaic strings, ensuring low power losses while maintaining flexibility. The lack of shielding does not negatively affect its use in typical solar installations, where the priority is galvanic isolation and mechanical resistance. The cable does not emit smoke or burning droplets in the event of a fire (in accordance with EN 13501-6 standards), increasing the safety of the facility.

Installation and Practical Benefits

During installation, it is important to consider several key aspects:

• The cable can be safely installed at temperatures ranging from -40°C to +90°C, providing great freedom of operation throughout the year.
• An approximate diameter of 5.4 mm facilitates routing the cable through standard grommets and seals used in inverters and PV combiner boxes.
• The flexible copper conductor construction minimizes the risk of cable cracking due to vibrations or thermal expansion of the roof's structural materials.

Thanks to double insulation (conductor insulation and outer sheath), the cable offers an additional layer of protection against short circuits and mechanical damage during operation. This solution is proven both by professionals executing large industrial installations and by investors building residential systems (BIPV).
