5. FAQ
5.1 What is the difference between 33KVA, 50KVA and 100KVA oil transformers in actual use?
The core difference lies in the maximum load capacity and applicable power supply scale. The 33KVA three phase oil transformer is suitable for small rural households, single small workshops and temporary low-power construction sites with low total power demand. The 50KVA oil power transformer is the most widely used conventional model, perfectly matching the power supply demand of ordinary residential communities, small commercial stores and standard factory workshops. The 100KVA high voltage transformer has larger load bearing capacity, which can meet the power demand of medium-sized processing plants, multi-storey office buildings and centralized public facilities. Users can select the corresponding capacity model according to the actual total power load and future power expansion demand of the scene.
