Product Description

1. DC resistance: when electric cable (finished) conducts electricity at 20°C, the DC resistance of its core of conductor shall be no greater than 5.09 Ω/km.
2. Voltage test in water: conduct voltage test (AC: 6.5kV or DC 15kV) the 20m electric cable (finished) for 5 min. after soaking in water at (20 ± 5)°C for 1h, without breakdown.
3. The length of sample with long-term resistance to DC voltage is 5m, and put it into the distilled water containing 3% NaCl at (85 ± 2)°C for (240 ± 2)h, exposing 30 cm above the water surface at both ends. Add DC voltage of 0.9kV between core of conductor and water (connect conductor wire core with the positive pole and water the negative one). Conduct voltage test in water after taking out the sample, with test voltage of 1kV AC, and without breakdown.
4. Insulation resistance: the insulation resistance of electric cable (finished) at 20°C shall be no less than 1,014Ω • cm, while electric cable (finished) at 90°C be insulated.
