1. DC resistance: 20 ℃, 0.4mm copper wire, 148Ω / km or less, 0.5mm copper wire, 95Ω / km or less.

2. Insulation electrical strength: 1min 1kv without breakdown between conductors 1min 3kv without breakdown between conductor and shield

3. Insulation resistance: Each core wire is grounded to the other cores, the control cable is greater than 10000MΩ.km, and the HYAT cable is greater than 3000MΩ.km.

4. Working capacitance: average value 52 ± 2nF / km

5. Far-end crosstalk defense: The average power of the specified combination at 150kHZ is greater than 69dB / km.
