10 Prohibitions for Transformer Installation and Operation!10 Prohibitions for Transformer Installation and Operation! Never install the transformer too far away—avoid placing it in remote mountains or wilderness. Excessive distance not only wastes cables and increases line losses, but also makes management and maintenance difficult. Never choose transformer capacity arbitrarily. Selecting the right capacity is essential. If the capacity is too small, the transformer may be overloaded and easily damaged—overloading beyond 30% should not exceed two hoursJames10/20/2025 -
