Do armored cables not require partitions?
Thread Content
As shown in the figure, does this specification mean that if there are instruments powered by 220V on site, armored cables can be used and placed directly in the cable tray? For example, armored 220V cables can be placed together with intrinsically safe cables without the need for a partition
Generally, armored cables and unarmored cables, or low-voltage cables and high-voltage cables, should be laid separately, or separated by partitions within the same cable tray or cable trench. This is because different types of cables can generate electromagnetic interference. Whether it is high-voltage or low-voltage cables, without proper shielding and isolation, they can affect the proper operation of other devices. However, the specific regulations may vary depending on the **, region, and specific power system. Regarding the specific situation you mentioned (placing 220V armored cables and intrinsically safe cables together without a partition), in theory, it might be possible if the shielding effect of the armored cables is sufficient and the system design takes potential interference into account. However, this needs to be determined based on the specific regulations in your area and the particular conditions of the installation environment. In general, whether armored cables are used or not, it is best to follow standard engineering practices and local regulations to ensure the safe and reliable operation of the power system. If you are still unsure, it is recommended that you consult a professional or the relevant department. .
