Control Cable Wire's 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] The power cable is used to transmit and distribute high-power electrical energy in the main line of the power system, and the control cable directly transmits the electrical energy from the distribution point of the power system to the power connection lines of various electrical equipment and appliances. The rated voltage of the power cable is generally 0.6/1kV and above, and the control cable is mainly 450/750V. When the power cable and control cable of the same specification are produced, the insulation and sheath thickness of the power cable is thicker than that of the control cable.
(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 insulated 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.
