Cable trays, supports, and clamps that hold single-core cables must avoid forming closed magnetic circuits; non-magnetic clamps made of copper tape or nylon should be preferred. Furthermore, eddy current loss is inversely proportional to the square of the cable spacing. Many modern buildings rely on cable trays to carry a lot of power and data lines. But with more and more cables and longer use, cables getting too hot is a big issue. Eddy currents are circular electric currents induced. | Jayson Patrick | 25 comments How to Avoid Severe Heating of Metal Cable Trays The eddy currents from. Metal trays also have electromagnetic effects that impact cable ampacities including increased cable conductor resistance caused by the flow of induced current in the metal tray and heat-generating eddy currents. These losses occur when a conductive material experiences a changing magnetic field, inducing circular currents within the material that generate. High-current power cables, motor drives, programmable logic controllers (PLCs), and densely packed control wiring can contribute significantly to the temperature rise on the plant floor.
