Oil-filled cables
Oil-filled communication cable model HYAT
Sheathed oil-filled cables HYAT22 HYYT23 HYAT23 HYAT53
Oil-filled cable Executive standard: YD/T322-1996
Structural characteristics of the oil-filled cables: HYAT local telecommunication cables using all chromatographic insulation, aluminum integrated sheath (ie, longitudinally of the cable, shielded ribbon with jacket bonded into one layer form a seal retainer), with excellent electrical performance, construction and convenient features.
Electrical properties of the oil-filled cables:
An oil-filled cable DC resistance: 20 ° C, 0.4 ≤ 148 0.5 ≤ 95.0 0.6 ≤ 65.8 0.8 ≤ 36.6
1min 1kv without breakdown between the two oil-filled cable insulation electric strength: conductor conductor and shielding breakdown in the 1min 3kv not
(3) oil-filled cable insulation resistance: each wire to ground with the rest of the wire core, HYAT cable greater than 3000MΩ.km
4 oil-filled cable capacitance: the average of 52 ± 2nF/km
5 Oil-filled cable FEXT defense degree: 150kHz specified combination of power when the average is greater than 69dB/km
