Thermal life of PV1-F en 50618 solar cable

PV1-F en 50618 solar cable is carried out according to EN 50618 Arrhenius curve with a temperature index of 120°C. Use of ime reach at 5000 hours. In general, the elongation at break or retention rate of insulation and sheath needed be more than 50%. Afterwards, a bending test at room temperature was performed. The diameter of the test rod is twice the outer diameter of en 50618 solar cable, and there should be no visible cracks on the surface of the sheath after the test. Required lifespan of PV1 F solar cable approaches to 25 years.

For photovoltaic applications, materials for outdoor use should be based on UV, ozone, severe temperature changes and chemical attack. The use of low-grade materials under such environmental stresses will result in brittle cable jackets and even break down the insulation of en 50618 solar cable . All of these conditions directly increase eletrical cable system losses, as well as increase the risk of PV1 F solar cable short circuits and, in the medium to long term, a higher probability of fire or personal injury.

To deal with the potential hazards caused by high temperatures, industrial wire manufacturers tend to use double-insulated rubber-sheathed electrical cables (eg H07 RNF). However, the standard version of this type of electrical cable is only permitted for use in environments with a higher operating temperature of 60°C. In Europe, the temperature that can be measured on the roof is as high as 100°C.  For these reasons, the use of dedicated en 50618 solar cable and components in solar energy systems is highly desirable.
