| Single-phase transformers

A single-phase transformer is a static electrical device that can increase or reduce the value of a single-phase alternating voltage. This type of transformer is commonly used to power electrical devices that require alternating voltage different from that of the standard single-phase network of 230 V.

EFC srl, with over 60 years of experience in the automation sector industrial, operates in the province of Bologna and throughout the national territory. The company is specialized in the production and sale of single-phase transformers for various uses industrials, including step-up and step-down transformers, as well as for equipment electromedical and other industrial applications.

> Insulation Class: F (155 °C)
> Insulation test voltage: max 5000 V



Structure of single-phase transformers

Single-phase transformers are essentially composed of a closed core made in ferromagnetic material and two windings of enamelled copper wire, wrapped around the nucleus.

The winding connected to the power line is called the primary winding, while the one connected to the user is called secondary winding.

To minimize eddy currents, the magnetic core is made up of thin sheets (with typical thickness between 0.35 and 0.50 mm) made with an alloy of iron and silicon. These laminations are covered with an insulating layer and carefully stacked one over the other.

The construction of the lamellar core, narrow and fixed viabrackets greenhouse-sheet metal, is designed for:

> Ensure optimal mechanical stability to the transformer
> Minimize energy losses due to hysteresis and eddy currents in iron
