The most important material of the cable is the core. The different functional cables have different standards for the core. The following is a detailed description of the quality of the different functional cable cores. The control cable is equipped with a copper core as standard. The power cable has an aluminum core and a copper core material. However, the power supply and the large-scale power supply of the system usually use a copper core, which is an ideal conductor material for the cable.
What is the main quality of cable for different purposes?
Power cables are mainly used in applications such as motor excitation, important power supplies, and mobile electrical equipment to maintain continuous high reliability. In the working environment, there are severe vibrations, explosion hazards, or corrosion to aluminum. The cables need to have fire resistance.

Power cables are mainly used in applications such as motor excitation, important power supplies, and mobile electrical equipment to maintain continuous high reliability. In the working environment, there are severe vibrations, explosion hazards, or corrosion to aluminum. The cables need to have fire resistance.
The power cable mainly adopting the copper core conductor is generally close to the high-temperature equipment, the public safety facility with high safety of the wiring system, and the underwater laying environment with large working cable and large number of cables.
two. Conventional ordinary cable
The ordinary cable used in the project should also be the national standard cable. The high-quality national standard cable is made of fine-stranded copper wire, and the cross section of the copper core meets the standard. In order to ensure the physical properties of the cable and the stability of the electrical performance, the multi-head brushed 4N copper conductor is generally used, the wire has bright luster, good toughness, low resistance, and long-term continuous load will not overheat.
High-quality cables are considered for various applications in production. They are required to have strong insulation and mechanical fatigue resistance, tensile strength and wear resistance.
three. Mobile application cable
Due to the special application environment, some cables need to be moved from time to time. For such cables, a small radius of bending movement is required. Generally, the minimum bending radius is 7.5 times of the outer diameter of the cable. If the cable that does not meet the standard is used in a mobile environment for a long time, the mechanical bending life will be greatly shortened. Therefore, to select the appropriate cable for this type of environment, you must pay attention to the cable outer diameter.
