Dry Type Electric Power Substation

AC Voltage Device Dry Type Power Transformer Flameproof GB3836.1-2000 Standard Description: Step down transformers are designed to reduce electrical voltage. Their primary voltage is greater than their secondary voltage. This kind of transformer "steps down" the voltage applied to it. For instance, a step down transformer is needed to use a 110v product in a country with a 220v supply. Mine use explosion proof dry-type transformer suitable for underground mines containing
