The single-phase pole-type transformer is designed for outdoor operation and is suitable for overhead distribution systems where safety is a determining factor. It is the most common transformer for urban and rural electrification in Mexico due to its ease of installation and the diverse range of low- and high-voltage connections.
Allowing great flexibility when interconnecting the medium-voltage distribution network to low-voltage consumer services.
