Mine communication cable 80 pairs, 80 pairs of mine how much detail of the telephone cable

Local telecommunication cables implementation of standards: YD/T322-1996 local telecommunication cables structural features: of HYA local telecommunication cables using all chromatographic insulation, aluminum sheath (cable longitudinal shielded ribbon with jacket bonded into together to form a seal protection layer), with excellent electrical performance, construction and convenient features. HYA-electrical properties of the local telecommunication cables: 1. DC resistance: 20 ° C, 0.4 ≤ 148 0.5 ≤ 95.0 0.6 ≤ 65.8 0.8 ≤ 36.6 2. Absolutely oil-filled communication cable 1min 1kv HYAT HYYT edge of the electrical strength: between conductors, do not hit wear Conductor and shield 1min 3kv without breakdown Insulation resistance: each wire to ground and the rest of the wire core of HYA cable is greater than 10000M Ω.km, HYAT cable is greater than 3000M Ω.km. 4 Capacitance: average of 52 ± 2nF/km 5. FEXT defense degree: 150kHz when the average power of the specified combination is greater than 69dB/km
