3 factors that make SOLARFLEX cables safe for direct burial

Using cables that can be directly buried offers several practical benefits. Firstly, eliminating the need for separate protective conduits helps save both installation costs and time. In addition, this installation method is flexible in application, suitable for urban infrastructure, solar energy systems, and industrial zones. Direct burial requires cables to be both durable and safe to ensure long-term performance – and this is precisely the strength of SOLARFLEX .

SOLARFLEX is designed with a core insulation and outer sheath made of high-quality cross-linked compound, which enhances electrical insulation and mechanical strength. This allows the cable to withstand soil pressure, impact during installation, and other physical stresses, ensuring stable and long-lasting signal transmission.

SOLARFLEX is water-resistant, which is certified according to DIN VDE 0285-525-2-21/ DIN EN 50525-2-21 Appendix E. This ensures the cable can resist moisture and underground water without compromising performance. However, it should be noted that the cable is not suitable for permanent installation in water.

Due to its special materials, SOLARFLEX offers excellent protection against UV radiation, ozone, and environmental weathering, meeting international standards:

• UV-resistant: according to DIN VDE 0283-618/ DIN EN 50618 Appendix E
• Ozone-resistant: according to DIN VDE 0283-618/ DIN EN 50618
• Weather-resistant: according to DIN VDE 0283-618/ DIN EN 50618 Appendix E

Thanks to these properties, the cable maintains high performance in outdoor conditions, even when exposed to sunlight or changing climatic conditions.

Proper installation is crucial to optimize performance and cable lifespan when directly burying SOLARFLEX. First, it is important to select the appropriate SOLARFLEX cable for the operating environment, ensuring that technical specifications such as voltage rating, heat resistance, moisture resistance, and mechanical strength meet project requirements. Correct cable selection minimizes the risk of damage, electrical faults, or signal disruption.

Additionally, carefully evaluating soil properties and the surrounding environment is essential. Factors such as soil moisture, pH level, mechanical load from overlying soil, and physical impacts during installation can all affect cable longevity. Understanding these factors allows for optimal installation planning, preventing issues such as breakage or performance degradation.

Finally, in special or harsh environments, it is still recommended to use additional protective pipes. This extra layer of protection shields SOLARFLEX from strong mechanical impacts, pests, or soil movement, ensuring stable operation and extended service life.
