Product Introduction

Step down voltage transformer is simply a device, which steps down or lowers the input voltage by a set ratio, so that the secondary voltage becomes lower than the primary voltage. This is essential in the case of electricity distribution, wherein the voltage from a power plant is supplied to the connected electrical stations and the grid. The step-down transformer works in sync with the electrical distribution system by taking the much higher power plant voltage and stepping it down to voltages that can be used in all kinds of electrical devices. Lowering the voltage levels is essential when distributing the energy that is supplied by power plants and distributed to end users.

A step-down transformer comprises of a primary and secondary winding and a magnetic core. The primary coil has more number of windings than the secondary coil. These coils are mostly made of copper or aluminum conductors.
