CRITERIA FOR SELECTION OF POWER CABLES
Product Details
ECONOMIC CONSIDERATIONS : The most economical construction and size of cable persistent with current carrying capacity and laying conditions has to be selected. A detailed study of 3 or 4 approximate sizes is made. Actual running costs are worked out taking into consideration |2R loss and interest, depreciation of the total cable cost. The size which gives minimum running costs is to be preferred.
SHORT CIRCUIT RATING : Short circuit rating depend on the expected level and the expected duration of the short circuit . In certain cases, a larger size of cable than be cable required for normal full load current may be needed. The cables with high KVA capacity are expected to carry short circuit current of high magnitude "AVOCAB" cables permit a short circuit temperature of 160
