Three-Phase Transformers
Three-phase transformers are designed for three-phase power systems used in industrial machinery, automation equipment, power distribution and other higher-power electrical applications.
DOREXS provides three-phase transformer solutions for voltage conversion, isolation, and industrial power applications. Electrical parameters and configurations can be selected according to the equipment power system and project requirements.
Typical applications: Industrial automation, machinery, motor systems, power equipment and renewable energy systems.
Dry Type Transformers
Dry-type transformers use air as a cooling medium. They do not use liquid insulating media, so they are safer and more environmentally friendly. They are widely used in high-security and low-maintenance situations such as commercial buildings, underground facilities, hospitals, schools, and industrial sites.Looking for a specific product? We also offer design solutions tailored to your requirements.
High-Frequency Transformers
High-frequency transformers are designed to operate at frequencies significantly above conventional 50/60Hz power transformers.
They are commonly used in switching power supplies, power conversion systems, inverters and other high-frequency power electronics.
Transformer design must consider operating frequency, input and output voltage, power, insulation, core material, winding configuration and thermal requirements.
DOREXS provides high-frequency transformer solutions for power electronic applications and supports project-specific customization.
Typical applications: SMPS, power conversion equipment, inverters and industrial electronics.
Toroidal Transformers
Toroidal transformers use a ring-shaped magnetic core and are commonly selected for applications requiring a compact structure, low magnetic leakage and low operating noise.
They can be used in electronic equipment, power supplies, instrumentation, audio equipment and other systems where available installation space and electromagnetic performance are important design considerations.
DOREXS provides standard and customized toroidal transformer solutions for different voltage and power requirements.
Typical applications: Power supplies, electronic equipment, instruments, audio systems and OEM equipment.

R-Core Transformers
R-core transformers use a continuous magnetic core with a round cross-section. Their core structure helps reduce magnetic leakage and supports compact, low-noise transformer designs.
DOREXS LHY1 R-core transformers are available for applications including measurement equipment, renewable energy equipment, medical electronics and other systems requiring reliable power conversion.
The LHY1 series supports customization according to application requirements.
Typical applications: Measurement equipment, medical electronics, renewable energy systems and precision electronic equipment.
EI-Core Transformers
EI-core transformers use laminated E-shaped and I-shaped magnetic core sections and are one of the most widely used transformer structures.
Their practical construction makes them suitable for industrial control equipment, power supplies, electronic devices and other general-purpose power conversion applications.
DOREXS provides EI-core transformer solutions in standard configurations and supports customization for project-specific requirements.
Typical applications: Industrial control, electronic equipment, power supplies and OEM products.
Isolation Transformers
Isolation transformers transfer AC power between circuits while providing galvanic isolation between the input and output windings.
They are commonly used where electrical isolation, equipment protection or reduction of unwanted electrical noise is required.
DOREXS provides both single-phase and three-phase isolation transformer solutions for industrial control systems, communication equipment, laboratory equipment, medical electronics and other sensitive electrical systems.
Typical applications: Industrial controls, instrumentation, communication systems, medical electronics and power equipment.
