Advanced Site Assembled (ASA) transformers: can be disassembled into transportation units and then transported to areas with severe transportation limitations by a low-floor trailer.
ASA transformers become cost-competitive
The more critical the transportation limitations, the more economically advantageous the ASA transformers become.
Additionally, ASA technology enables large three-phase transformers to be made instead of the single phase 3-units configuration, and substantially reduces installation space.
ASA transformers are assembled in a clean house at the site with high reliability and shorter time.
