Main electrical performance:
1. Dc resistance: 20 °C, 0.4 ≤148Ω/km 0.5 ≤95.0Ω/km 0.6 ≤65.8Ω/km 0.8 ≤36.6 Ω/km2.
2.The insulated electrical strength: 1 min 1 kv no breakdown between the conductor and conductor shielding 1 min 3 kv is not
breakdown
3. The insulation resistance: each conductor and the rest of the grounding wire core, the charge cable is more than 10000 m Ω. Km,
filling type cable is more than 3000 m Ω. Km.
4. Work capacity: average 52 plus or minus 2 nf/km
5. The far end crosstalk defense: 150 KHZ specified when the combination of the average power is greater than 69 db/km.
