Low-voltage Cable Load Capacity, Please See The Low-voltage Cable Load Capacity Table

In the daily work of many people should be involved in electrical things, in the current living conditions, a wide range of electronic equipment, the use of voltage is also different, there are high-voltage and low-voltage, then in the use of these electrical equipment when his power supply cable also needs to use low-voltage cable, which is necessary, but some production students in the manufacture of equipment will need a detailed low-voltage cable load table parameters. Otherwise, it will lead to equipment manufacturers to manufacture equipment in the process of using the abnormal, then we will popularize the following low-voltage cable load capacity and low-voltage cable load table it!

What is the low-voltage cable load capacity

Low-voltage cable capacity is a cable conductor in the case of insulation and sheath temperature limits can be sustained under the safety of carrying current, low-voltage cable capacity table "to amperage or, more simply, amperage as the unit". As the current flow in the cable conductor increases, the heat generated in the conductor also increases. The heat generated in the conductor must be dissipated to the environment. If the heat does not escape, the conductor temperature will continue to rise until the cable conductor exceeds the current insulator temperature limit rating, and the cable insulation will deteriorate, indirectly resulting in cable damage.

Low-voltage cables should have a current carrying capacity equal to or exceeding the maximum current the cable is expected to carry during its service life, but not exceeding its temperature rating. The temperature rating depends on the heat resistance of the materials used for the cable insulation and sheathing. The higher the heat resistance of a material, the less likely it is to deteriorate at higher temperatures. The most common conductor temperature rating for low-voltage cables is 90°C, but for some special-purpose cables, conductor temperatures can be as low as 60°C or as high as 1,200°C. Although conductor temperature plays an important role in determining the load capacity rating.

Well, the above is about the low-voltage cable load capacity and low-voltage cable load capacity table" is introduced, I hope it can help you friends! If you want to know more information, please continue to pay attention to XSD Cable.
