Product Description: sheathed oil-filled cables HYAT22 HYYT23 HYAT23 HYAT53
Oil-filled cable Executive standard: YD/T322-1996
Oil-filled cables structural features: HYAT local telecommunication cable full chromatography insulation, aluminum integrated sheath (ie, longitudinally of the cable, shielded ribbon with jacket bonded into one to form a seal protection layer), 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
Between the two oil-filled cable insulation electric strength: conductor 1min 1kv breakdown Conductors and shielding the 1min 3kv not breakdown
(3) oil-filled cable insulation resistance: each wire to ground with the rest of the wire core HYAT cable is greater than 3000M Ω. Km.
4 oil-filled cable capacitance: the average of 52 ± 2nF/km
(5) oil-filled cables FEXT defense degree: 150kHz when the average specified combination of power greater than 69dB/km.
