Factors and coefficients considered in selecting the cross-sectional area of the core wires in UPS incoming cables

Thread Content

I compared the cable specifications and UPS capacity from my previous projects, with the results shown below: UPS capacity, converted to active power, actual active power, type of incoming cable, length of incoming cable. Under normal circumstances, cables are selected based on the same power level. Project 1: 50KVA, 40KW, 34.6KW; cable type: 4x95+50, length: 48m; alternative cable type: 4x35+16. Project 2: 20KVA, 16KW, 12.16KW; cable type: 4x70+35, length: 28m; alternative cable type: 5x6. Project 3: 30KVA, 24KW, actual value unknown; cable type: 3x70, length: 42m; alternative cable type: 4x25+16 (in case of a five-core cable). Since all of these are AC UPS cabinets, why are their incoming cables so much larger than those used in conventional applications? What factors need to be considered when selecting the cross-sectional area of the core wires in the UPS incoming cable? What are the typical values for coefficients? Please give me some advice!
