Performance Characteristics Of Control Cables

Control cable is a PVC insulated and PVC sheathed control cable suitable for use in industrial and mining enterprises, energy and transportation departments, and for controlling and protecting circuits with AC rated voltage below 450/750 volts.
1. DC resistance: 20 ℃, 0.4mm copper wire, less than or equal to 148 Ω/km, 0.5mm copper wire, less than or equal to 95 Ω/km.
2. Insulation electrical strength: no breakdown between conductors at 1kV for 1 minute, and no breakdown between conductors and shields at 3kV for 1 minute
3. Insulation resistance: Each core wire is grounded with the remaining cores, and the control cable is greater than 10000M Ω· km, while the HYAT cable is greater than 3000M Ω· km.
4. Working capacitance: average value 52 ± 2nF/km
5. Remote crosstalk defense: The average power of the specified combination at 150kHz is greater than 69dB/km.
