Abstract :
An attempt is made to show that the Namgne method (R. Namgne and L. Ashbaugh, 1977) is simple and practical bt clarifying the analytic evaluation, and presenting a simpler step-by-step method for calculation of allowable ampacity. Using this method, a computer program has been developed to generate tables of correction factors which can be directly applied to the ICEA P-54-440 ampacities. Experimental results and the theoretical basis of method presented in references, are reviewed, and a comparison is made of the Namgne method with other approaches
