5.1 What is the difference in application scenarios between 30Kva, 50Kva and 80Kva 10kV 400V oil immersed transformers?
The three capacity models are applicable to different load scenarios. The 30Kva oil immersed distribution transformer is mostly used for single village decentralized power supply, small community unit power distribution and simple temporary engineering power supply with extremely low load. The 50Kva model is the most mainstream universal model, suitable for ordinary rural residential clusters, small shops and small workshop power supply, balancing load demand and cost. The 80Kva model is suitable for suburban residential areas, medium-sized processing workshops and multi-storey office buildings with relatively concentrated power consumption and slightly higher load. Users can select the corresponding capacity according to the actual peak load of the site to avoid equipment overload operation or capacity waste.
