PV1-F Solar Cable
Photovoltaic Special cables generally refer to the cables connected in series to the combiner box in photovoltaic systems, mainly used for transmitting the direct current energy generated by photovoltaic panels. Its usage environment requires it to meet characteristics such as UV resistance, ozone resistance, resistance to severe temperature changes (heat and cold resistance), oil resistance, and chemical erosion resistance. The current corresponding product standard for photovoltaic cables is 2PfG1169/08.2007

Temperature Range
- Ambient Temperature: The ambient temperature range for these cables is from - 40 ℃ to + 90 ℃. This wide range allows the cables to be used in various geographical and climatic conditions.
- Working Temperature of Conductor: The working temperature of the conductor can reach 120 ℃. Although the operating temperature of the cable is up to 90 ℃, according to EN60216 - 1, the temperature index of its insulation and sheath is 120 ℃. The expected service life is 25 years, and the short - circuit temperature for 5 seconds is 200 ℃. This high - temperature resistance ensures the long - term stability and safety of the cable operation.
Conductor Structure
- Number of Cores: The number of cores of the structural conductor is 1.
- Conductor Type: The conductor is a type 5 conductor in EN60228 (IEC60228, GB/T3956) and must be tin - plated. Tin - plating enhances the conductor's corrosion resistance and electrical conductivity.
- Cross - section: The cross - section of the conductor is available in 1.5, 2.5, 4, 6, 10, 16mm2, providing flexibility for different power transmission requirements.
Material Selection
The materials used for outdoor use should be carefully determined based on factors such as UV, ozone, temperature changes, and chemical erosion. Using low - grade materials under such stress will make the cable sheath fragile and may even decompose the cable insulation layer. All of these situations will directly lead to cable loss, and the risk of cable short - circuits will also increase. In the medium to long term, the likelihood of fire or personal injury is also higher. Photovoltaic dedicated cables are designed to transmit electrical energy from photovoltaic panels, with a conductor operating temperature of 120 ° C (can be used for 20000 hours). This rating is equivalent to being used for 25 years under temperature conditions of 90 ℃. When the temperature is below 90 ℃, 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.
