ZR-HYAT flame retardant communication cableImplement YD/T322-1996 standard. Adopting full chromatographic insulation and aluminum-plastic composite sheath (i.e. the longitudinal shielding aluminum tape of the cable is bonded to the sheath to form a sealed protective layer), it has the characteristics of electrical performance and convenient construction.

Main electrical properties of ZR-HYAT flame-retardant communication cable:

1. DC resistance: 20 ℃, 0.4 ≤ 148, 0.5 ≤ 95.0, 0.6 ≤ 65.8, 0.8 ≤ 36.6

2. Absolute oil filled communication cable HYAT HYYT edge electrical strength: no breakdown between conductors at 1kV for 1 minute, and no breakdown between conductors and shielding at 3kV for 1 minute

3. Insulation resistance: Each core wire is grounded to the rest of the wire cores, with HYA cables exceeding 10000M Ω· km and HYAT cables exceeding 3000M Ω· km.

4. Working capacitance: average value 52 ± 2nF/km

5. Remote crosstalk defense: The average combined power at 150kHz is greater than 69dB/km
