2. Isolated electrical force: 1 min 1 kV without breakage between the conductor and the conductor shield; 1 min 3 kV without breakage
3. Insulation resistance: Each conductor and the rest of the core of the grounding cable, the load cable is more than 10000 mΩ.Km, the filler cable type is more than 3000 mΩ.Km
4. Working capacity: average 52 plus or minus 2 nf/km
5. Crosstalk defense at the other end: 150 KHZ specified when the average power combination is greater than 69 dB/km.

Suitable for local telecommunications networks in towns and cities, it can also be used for connecting public networks to private networks. Aerial installations require the use of messenger cable bearings. Under ambient conditions of -30°C to +60°C, the cable's mechanical and electrical properties remain unchanged.
