Three-Phase Transformers

A three-phase transformer is an electrical device designed to transfer electrical energy between three-phase power systems at different voltage levels.

Toroidal Transformers

A toroidal transformer is a type of electrical transformer with a ring-shaped (doughnut-shaped) magnetic core, usually made of ferrite or laminated silicon steel, around which the wire windings are wrapped.

High Frequency Transformers

A high-frequency transformer is a type of transformer designed to operate at frequencies higher than the standard 50/60 Hz, typically in the kHz to MHz range.

Magnetic Ring Inductance Transformers

A Magnetic Ring Inductance Transformer typically refers to a transformer or inductor that uses a toroidal (ring-shaped) magnetic core, often made of ferrite or powdered iron.

Reactor Transformers

A reactor transformer (sometimes called a transformer with a reactor, or series reactor transformer) is a specialized transformer that includes or works in conjunction with a reactor (inductor) to control current, voltage, or power quality in an electrical system.

High Power Transformers

High Power Core Transformers
High Power Toroidal Transformers High Power Amorphous Transformers
for grid distribution transformers, renewable energy (solar/wind), energy-saving projects iin industrial or commercial facilities

Audio Transformers

An audio transformer is a specialized transformer used in audio signal applications to transfer sound (analog electrical signals) between circuits while maintaining signal integrity and providing isolation, impedance matching, and noise reduction.

EI Power Transformers

An EI transformer (often written as “EL transformer” by mistake) uses a stack of alternating E- and I-shaped laminated steel sheets to form the magnetic core. Wire windings are wrapped around the central leg of the “E”, and the “I” piece closes the magnetic path.

EV Charging Transformers

Katoy EV Transformers play a vital role in the manufacturing of electric vehicle (EV) charging stations, converting high voltage electricity from the grid to lower voltages suitable for charging vehicles.

Welding Machine  Transformers

Katoy transformers are commonly used in welding equipment. The main function of the transformer is to convert standard electrical power (high-voltage, low-current) into a form that is suitable for welding.
