W.O. 04-5440-722/31971 Wrap Cable Tray 3088 Thermal Analysis - Rev 1 October 20, 1985 Ref: Memo to S.N. Maruvada from I. M. Sommerville, Cable Tray 3088 Thermal Analysis, 10/11/85.
l The thermal analysis for cable tray 3088 with the 1/2" of Thermo-Lag 330-1 has been re-done to determine the temperatures at a lower heat load.
The analysis is identical to that of the reference menc with the exception of the heat load.
l Results are given in figure 1 which show two curves of heat load vs peak cable temperature.
I The temperature is 151.1 F and 145.6 F for the 12" and 18" trays respectively for the heat load of 7.28 wattr,/ft.
It should be noted that the analyses were performed for a horizontal tray; the temperatures will be slightly lower if the trays are vertical.
