Description
Name: oil filled communication cable
Model: HYAT
Executive standard: YD / t322-1996
HYAT municipal communication cable adopts full spectrum insulation and aluminum-plastic comprehensive sheath (that is, the longitudinal shielding aluminum tape of the cable is bonded with the sheath to form a sealing sheath), which has the characteristics of superior electrical performance and convenient construction.
Main electrical performance of oil filled cable: 1 DC resistance of oil filled cable: 20 ℃, 0.4 ≤ 148, 0.5 ≤ 95.0, 0.6 ≤ 65.8, 0.8 ≤ 36.6 2 Electrical strength of oil filled cable insulation: 1kV no breakdown between conductors for 1min and 3KV no breakdown between conductors and shielding for 1min 3 Insulation resistance of oil filled cable: each core is grounded with other cores, and HYAT cable is greater than 3000m Ω km。 4. Working capacitance of oil filled cable: average 52 ± 2NF / km5 Far end crosstalk defense of oil filled cable: the average power of the specified combination at 150kHz is greater than 69db / km.
