Introduce the application environment of PV photovoltaic cables

As for photovoltaic applications, the materials used outdoors should be determined based on ultraviolet radiation, ozone, severe temperature changes, and chemical erosion. Using low-grade materials under such environmental stress will cause the cable sheath to be fragile and even decompose the cable insulation layer. All of these situations will directly increase the loss of the cable system, and the risk of cable short circuit will also increase. From this, it can be seen that the possibility of fire or personal injury is also higher.

HUBER+SUHNER RADOX ® Solar cable is an electron beam cross-linked cable with a rated temperature of 120 ° C. It can withstand harsh weather conditions and mechanical impacts in its equipment. According to the standard IEC216, RADOX ® The service life of solar cables in outdoor environments is 8 times that of rubber cables and 32 times that of PVC cables. These cables and components not only have excellent weather resistance, UV and ozone resistance, but also can withstand a wider range of temperature changes (e.g. from -40 ° C to 125 ° C).

To cope with potential hazards caused by high temperatures, manufacturers tend to use double-layer insulated rubber sheathed cables (e.g. H07 RNF). But the standard version of such cables is only allowed for use in environments with high operating temperatures of 60 ° C. In Europe, the temperature value that can be measured on the roof is as high as 100 ° C.

RADOX ® The rated temperature of the solar cable is 120 ° C (can be used for 20000 hours). This rated value is equivalent to 18 years of use under continuous temperature conditions of 90 ° C; And when the temperature is below 90 ° C, its service life is longer. Usually, it is required that the service life of solar energy equipment should reach 20 to 30 years or more.

Based on the above reasons, it is very necessary to use solar cables and components in solar energy systems.
