FAQ

What is a Dry-Type Transformer, and how does it work?

A:ATrasformatore a seccois a power distribution device that uses air or solid insulation instead of liquid coolant. It steps up or steps down voltage levels for safe and efficient power distribution. The transformer consists of primary and secondary windings wrapped around a laminated steel core. When an alternating current passes through the primary winding, it generates a magnetic field that induces voltage in the secondary winding, allowing for voltage transformation without direct electrical contact.
