Solar Photovoltaic Cable

Cable model: PV1-F Rated voltage: ACU0/U=0.6/1kV DC 1.8kV model; Cable model: H1Z2Z2-K Rated voltage: ACU0/U=0.6/1kV DC 1.5kV model (core to core, non grounded, loop without load) (If the cable is used in DC, the rated voltage between its conductors should not exceed 1.5 times the rated AC value U of the cable. In single-phase grounded DC, this value should be multiplied by a coefficient of 0.5.)

Temperature range: ambient temperature: -40 ℃ to+90 ℃. Working temperature of conductor: 120 ℃ (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 ℃. The number of cores of structural conductor: 1. The conductor is a type 5 conductor in EN60228 (IEC60228, GB/T3956) and must be tin plated. The cross-section of the conductor is 1.5, 2.5, 4, 6, 10, 16mm2. The materials used for outdoor use should be determined based on UV, ozone, temperature changes, and chemical erosion. Using low-grade materials under such stress will make the cable sheath fragile and 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 cable is a type of cable used 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.
