Introduction And Performance Characteristics Of Control Cables

The Control Cable Wire is a PVC insulated and PVC sheathed control cable suitable for industrial and mining enterprises, energy and transportation departments, and for the control and protection of lines with an AC rated voltage below 450/750 volts.

Performance characteristics

1. DC resistance: 20℃, 0.4mm copper wire, less than or equal to 148Ω/km, 0.5mm copper wire, less than or equal to 95Ω/km.

2. Dielectric strength: 1min 1kv between conductors without breakdown, conductor and shield 1min 3kv without breakdown

3. Insulation resistance: each core wire is grounded with other cores, the control cable is greater than 10000MΩ.km, and the HYAT cable is greater than 3000MΩ.km.
4. Working Capacitance: Average 52±2nF/km

5. Far-end crosstalk defense: The average power of the specified combination at 150kHZ is greater than 69dB/km.

Performance difference

Control cables have the characteristics of moisture-proof, anti-corrosion, and damage-proof, and can be laid in tunnels or cable trenches.

(1) Control cables are cables for electrical equipment, and power cables are two of the five categories of cables.

(2) The standard for control cables is 9330, and the standard for power cables is GB12706.

(3) The color of the insulating core of the control cable is generally black and white, and the low voltage of the power cable is generally color-separated.

(4) The cross-section of the control cable is generally not more than 10 square meters, and the power cable is mainly used to transmit electricity, and generally has a large cross-section.

In terms of the number of cable cores, the power cable is generally 5 cores at most according to the requirements of the power grid, while the control cable is used to transmit control signals, and the number of cores is more...
