The materials used for outdoor photovoltaic cables must take into account ultraviolet rays, ozone, strong temperature differences, and chemical corrosion. The use of inferior materials in the above environment will make the cable sheath fragile and even reduce the insulation performance of the cable. In the short term, these situations will directly increase the loss of the cable system, and at the same time the risk of cable short circuit. In the medium and long term, it is prone to fire or explosion，or casualties.
The solar cable is an electron beam cross-linked cable with a rated temperature of 120°C, which can withstand extreme weather and mechanical shocks in its equipment. According to the international standard IEC216, the service life of RADOX® 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 the best weather resistance, UV protection, and ozone resistance, but they can also withstand more temperature changes (for example, from –40°C to 125°C).
In order to cope with the potential hazards caused by high temperature, manufacturers tend to use cables with double-layer insulated rubber sheaths. However, the standard version of this cable is only allowed to be used in an environment with a maximum operating temperature of 60°C. In Europe, the measured roof temperature is as high as 100°C.
The rated temperature of the solar cable is 120°C (usable for 20,000 hours). This grade is equivalent to 18 years of continuous use at a temperature of 90°C; when the temperature is lower than 90°C, its service life is longer. Generally speaking, it is required that the service life of solar energy equipment should reach more than 20-30 years.
Based on the above reasons, it is very necessary to use special solar cables and components in solar systems. uses special tinned copper solar photovoltaic cables. The product quality is excellent and it is a good choice.
