What is the primary purpose of using a steel plate in cable installations?

The primary purpose of using a steel plate in cable installations is to prevent cable damage. Steel plates act as a protective barrier for cables, especially in areas where cables might be exposed to physical stress, such as in walls or near heavy equipment. By using a steel plate, installers can reduce the risk of abrasion, cuts, or crushing that could occur from objects or pressure applied to the cable. This protection ensures the integrity and functionality of the cables over time, which is critical in maintaining a reliable cabling infrastructure.

While supporting cables can be an ancillary benefit, and aesthetics might be a consideration in some designs, the foremost reason for installing steel plates is to safeguard the cables from potential damage in their operating environment. Indicating cable type is also not a function of steel plates, as that would typically be done through labeling or markings, not a physical barrier.
