[0002] At present, outdoor transformers need to be fixed by channel steel during installation. Channel steel, as the bottom support structure of large transformers, can fix the transformer on the pole to ensure its stability. This support is essential for the safe operation of the transformer. Moreover, channel steel can bear the weight of the transformer and distribute it over a larger area, thereby reducing the pressure on local areas. This helps to protect the internal structure of the transformer and prevent it from being damaged by excessive pressure.
