Aircraft cable manufacturers will show you: What is the difference between control cables and power cables

Nowadays, the pace of industrial development in all walks of life is getting faster and faster, and there are many types of industries. Many of these industries use corresponding wires and cables. Aircraft cable manufacturers tell you, for example, some of the machinery industry uses control cables, and some use power cables. The concept of these two words may be unfamiliar to some non-professionals. What are the essence of control cables and power cables? What's the difference? The staff of the aircraft cable manufacturer below will explain it to you.
Aircraft cable manufacturers tell you the difference between control cables and power cables:
Aircraft cable manufacturers tell you their difference in meaning:
1. The meaning of power cable: power cable refers to a cable with a large wire diameter, generally 3-core or 4-core, with thick interphase insulation and metal armor protection on the outside.
2. The meaning of the control cable: The control cable is a PVC insulated and PVC sheathed control cable suitable for industrial and mining enterprises, energy and transportation departments, and used for control and protection lines with AC rated voltage below 450/750 volts.
Aircraft cable manufacturers tell you that their voltage levels are different:
1. The power cable transmits continuous current, with a wide range of voltage levels: 1KV~220KV, larger current (larger conductor cross-section), less cable cores, 3 cores, 4 cores (three-phase four-wire system), 5-core (three-phase five-wire system).
2. The control cable transmits signals, and the voltage range is narrow: 450/750v and below, the current is relatively small (that is, the conductor cross-section is small), and the number of cable cores is large, ranging from 2 cores to 61 cores, or even more. The control cable also adopts various core structures, shielding and other measures to obtain satisfactory electromagnetic compatibility effects.
Aircraft cable manufacturers tell you their application differences:
1. Application of power cables: The wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables (plastic cables, oil-paper cables (basically replaced by plastic power cables), rubber-sheathed cables, Overhead insulated cables), branch cables (replace part of the busbars), electromagnetic wires, and electrical equipment wires and cables for power equipment.
2. Application of control cables: used in computer systems and information transmission systems, mainly local telephone cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communications or other composite cables. Among them, shielded control cables are widely used in power plants and power stations because of their good shielding performance.
Aircraft cable manufacturers tell you the difference in the number of cores:
Power cable: The wire diameter is thick, generally 3-core or 4-core.
Control cable: There are more cores, 61 cores are more according to the standard.
From the differences in the above aspects, it can be seen that the main line of the power system is used to transmit and distribute large-function electrical energy. The control cable directly transmits electrical energy from the power distribution point of the power system to the power connections of various electrical equipment and appliances. line. The rated voltage of the power cable is generally 0.6/1kV and above, and the control cable is mainly 450/750V. When power cables and control cables of the same specification are produced, the thickness of the insulation and sheath of the power cables is thicker than that of the control cables.
