Highest temperature of cables in cable trays

The maximum permissible temperature of cables in cable trays depends on the insulation type, ambient conditions, and tray ventilation, typically ranging from 60°C for standard installations up to 90°C or higher for XLPE-insulated cables.Key Considerations

Cable Insulation Material: The maximum conductor temperature is determined by the insulation type. For example, PVC-insulated cables generally have a lower permissible temperature than XLPE-insulated cables, which can handle higher temperatures without degradation. Exceeding these limits can cause insulation melting, short circuits, or accelerated aging of the cable . Ambient Temperature: Standard installation cables are rated for ambient temperatures between -15°C and 60°C. If the environment is hotter, the cable temperature rises further due to the Joule effect, reducing lifespan and increasing the risk of failure . Fire-resistant cables can withstand higher temperatures temporarily during a fire but will need replacement afterward . Cable Tray Design and Ventilation: Ladder or ventilated cable trays allow maximum airflow, helping dissipate heat from the cables. Solid-bottom trays can restrict airflow, potentially increasing cable temperature. Proper tray selection and spacing are essential to ensure that the cable insulation does not exceed its maximum operating temperature . Standards and Guidelines: IEC 61537 provides guidance on cable tray construction, load, and environmental considerations, ensuring that trays support safe cable operation under expected thermal loads . NEC guidelines also specify tray types and installation practices to prevent overheating, particularly for single conductor and MV cables . Practical Recommendations:

  • Avoid continuous loading at maximum conductor temperature to prevent accelerated thermal aging .
  • Ensure proper tray ventilation and spacing to allow heat dissipation.
  • Select cable types suitable for expected ambient temperatures and electrical load.
  • Monitor cable temperatures during installation and operation, especially in high-temperature environments . By considering insulation type, ambient conditions, and tray design, cables in cable trays can operate safely without exceeding their maximum permissible temperature, ensuring longevity and reducing fire risk.
