Solarflex-X PV1-F 1x4 red cable for photovoltaic installations, 2-standard, double insulation, Elukabel 705775

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 harmful chemical and oil-based factors. This is not merely a matter of corrosion protection – this material guarantees the stability of electrical parameters even at extreme temperatures. The cable can operate within a range from -40 °C to +90 °C, allowing for installation and operation in virtually any climatic conditions, from freezing winters to hot summers.

For the installer, this means reduced need for additional mechanical protection in areas exposed to abrasion or mechanical damage. For the end user, it is a guarantee of system longevity – the manufacturer declares an operational lifespan of up to 25 years. It is worth noting that this construction does not emit smoke nor form burning droplets when exposed to fire (in accordance with EN 13501-6), which is a significant advantage when installing on roofs or in enclosed technical spaces.

Conductor Construction and Installation Flexibility

The interior of the cable consists of a copper conductor divided into many fine strands (flexibility class 5). This solution makes the cable extremely flexible and easy to handle, significantly facilitating installation work on complex cable routes or during panel connections. Despite its flexible construction, the cable maintains high resistance to abrasion when pulled through protective conduits or guides.

The nominal cross-section is 4 mm², allowing for safe current transmission in standard photovoltaic string circuits at a rated voltage of 1000 V (U) and 600 V (U0). The external diameter of the cable is approximately 5.4 mm, making it a compact installation component that does not excessively burden mounting structures. The outer sheath color is red, which is standard for cables running from modules to the inverter (positive side), facilitating quick polarity identification during service inspections or system expansions.

Key Features and Operational Parameters

By choosing this cable, you receive a product meeting rigorous safety standards for the renewable energy sector. Its construction eliminates the risk of insulation degradation due to sun exposure or temperature fluctuations, which is a common cause of failure in cheaper alternatives. The cable features a rated voltage of 1000 V and a conductor cross-section of 4 mm² made of copper in flexibility class 5. The polyolefin insulation ensures resistance to temperatures from -40 °C to +90 °C with an external diameter of approximately 5.4 mm. Due to the lack of shielding and optimization for weight and flexibility, this cable is suitable for both small residential installations and larger solar farms. Installation is simple thanks to the conductor's flexibility, and subsequent operation is maintenance-free for years, with a declared service life of up to 25 years.
