Typical Case
Lingxing wood industry group limited company, a multi-line operation company, administrates several board manufacture plants in Anhui province of China. One of them named Linxing board industry company is able to annually produce 60000 cubic meters boards. This plant uses two sets of 2000KVA dry-type transformers, as well as its power distribution uses centralized compensation cabinets. Power factor rises to 0.95. We make a detailed calculation about the electricity network parameters of this plant as following:
