If we were to operate the CHP via the line of the lathe or bell, cable fire would occur due to the excessive heat.eval(ez_write_tag([[728,90],'electronicbase_net-medrectangle-3','ezslot_9',107,'0','0'])); The cross section refers to the area of each wire of a cable and its size depends on several factors. The cable capacity / ampacity calculation and cable sizing are based on the NEC accepted Neher-McGrath method and IEC 60287 standard for steady-state temperature calculation. Therefore, in the next few sections, we will explain how these sizes are arrived at. This makes it difficult to calculate the temperature when the airflow is not known. Thermtest is furnishing this item "as is". 2 Heat transfer is one-dimensional since there is thermal symmetry about the centerline and no variation in the axial direction. 3 Thermal conductivities are constant. If you know the resistance of the wire, then the heat dissipated by the wire is simply the power: ##dQ/dt=I^2R##, expressing this in terms of resistivity, we have: ##dQ/dt=I^2\rho l/A##. Hot legs are undesirable, so the power used to heat the legs can be regarded as "lost".
