What are the properties of PV DC cables?

I. What are the performance of photovoltaic DC cable? Photovoltaic DC wire and cable performance characteristics: 1, high temperature pressure performance. Temperature (140 ± 3) ℃, time 240min, k = 0.6, indentation depth does not exceed 50% of the total thickness of the insulation and sheath. And AC6.5kV, 5min voltage test, requires no breakdown. 2, high resistance to acid and alkali solutions. Two groups of samples were immersed in a concentration of 45g/L oxalic acid solution and a concentration of 40g/L sodium hydroxide solution at a temperature of 23 ℃ for 168h, compared with the solution before immersion, the rate of change of tensile strength ≤ ± 30%, elongation at break ≥. 3, good compatibility. Cable as a whole by 7 × 24h, (135 ± 2)℃ aging, insulation aging before and after the tensile strength change rate ≤ ± 30%, elongation at break change rate ≤ ± 30%; sheath aging before and after the tensile strength change rate of ≤ -30%, elongation at break change rate of ≤ ± 30%.4, good weather resistance / UV performance.
