Information
Shandong Luqing Cable Co., Ltd. Photovoltaic line electrical performance
DC resistance
The DC resistance of the conductive core at the finished cable at 20 ° C is not greater than 5.09Ω / km.
2 Immersion voltage test
The finished cable (20m) does not break through a 5min voltage test (AC 6.5kV or DC 15kV) after immersion in water at (20 ± 5) ℃ for 1 hour.
3 Long-term withstand DC voltage
The sample was 5 m long, and was placed in distilled water containing 3% sodium chloride (NaCl) at (85 ± 2) ° C for (240 ± 2) h. Both ends of the sample were exposed to the water surface for 30 cm. DC 0.9kV voltage is applied between the core and the water (the conductive core is connected to the positive electrode, and the water is connected to the negative electrode). After the sample is taken out, a water immersion voltage test is performed. The test voltage is 1 kV AC, and no breakdown is required.
