Single-phase cable heating up when passing through cable tray
Cables heat up for a few main reasons: Too Much Load: As we need more power, cables carry more electricity. If a cable carries more current than it's built for, it will get hot. This makes it hard for the. imity effects due to harmonic distortion. Although in recent years, some movement has taken place in the standards to offer harmonic de-rating factors, heating in cables due to skin and proximity ef ects has not been quantified effectively. The conductors are arranged in the tray. A three-phase cable won't cause circulating current problems because the magnetic fields cancel, or at least they do when you move away from the immediate vicinity of the cable. Can you confirm whether this is a single or three phase installation? If we learn from our mistakes I'm getting a great.
