What is the difference between control cables and communication cables? Control cables are used to transmit electrical signals, suitable for PVC insulated control cables used in control systems of industrial and mining enterprises, and used to control and protect lines with AC rated voltages lower than 450/750V. The communication cable is used to transmit data signals, and the communication cable is shielded to prevent external signal interference. 1. Use characteristics of the control cable. Rated voltage: 450/750V. The long-term allowable working temperature of the wire core is 70°C to 95°C, and the cable laying temperature is not lower than 0°C. The recommended allowable bending radius of the cable is as follows: for unarmoured cables, it must not be less than 6 times the outer diameter of the cable; for cables with armor or copper tape shielding, it must not be less than 12 times the outer diameter of the cable. Shielded flexible cable, not less than 6 times the outer diameter of the cable. Control cables generally refer to equipment power supply and signal control. Representative models: KVV, KYJV and other instrument lines, etc. 2. Control the electrical performance of the cable. Control cable DC resistance: 20℃, 0.4mm copper wire, less than or equal to 148ω. 0.5mm copper wire, less than or equal to 95Ω. Insulation electric strength: 1min1kv between conductors does not break down conductors and shielding 1min3kv does not break down. Insulation resistance: each core wire is grounded with other core wires, the control cable is greater than 10,000 Mω, km, and the HYAT cable is greater than 3000 Mω, km. Working capacitance: average 52±2nF. Far-end crosstalk defense: at 150kHZ, the average power value of the specified combination is greater than 69db.km. .
