Since the high voltages carried in the wires are significantly greater than what is needed in-home, transformers are also used extensively in electronic products to decrease (or step-down) the supply voltage to a level suitable for the low voltage circuits they contain. We know transformers, from Toroid, Ferrite, Laminated Iron Core, High Voltage, Auto Transformers, Audio, Encapsulated, Power Transformers, and Instrument Transformers which sold under different brands. We used to outsource this product as per the end user requirement. This is what we do and we do it well.
