1. Corrosion resistance: The conductor is made of tinned soft copper wire, which has good corrosion resistance.
2. Cold resistance: The insulation is made of cold-resistant, low-smoke, halogen-free materials, cold-resistant to -40°C, and has good cold resistance.
3. High temperature resistance: The sheath is made of high temperature, low smoke and halogen-free materials, with a temperature resistance level of up to 120 °C and excellent high temperature resistance.
4. Other properties: After being irradiated, the insulating sheath of photovoltaic cable has the characteristics of anti-ultraviolet radiation, oil resistance and long service life.
As the world's largest solar market, Germany has encountered all the problems associated with cable selection. Today in Germany, more than 50% of the installations use
DC cables are installed outdoors. It is generally recommended to select photovoltaic special cables that have been cross-linked by irradiation. After high-energy electron beam irradiation, the molecular structure of the insulating layer material of the cable changes from linear to three-dimensional network molecular structure, which is resistant to temperature.
The grade is increased from non-cross-linked 70°C to 90°C, 105°C, 125°C, 135°C, and even 150°C, which is 15-50% higher than the current carrying capacity of cables of the same specification, and can withstand severe temperature changes and chemical erosion. Used outdoors for over 25 years.
