An auto transformer is a versatile and efficient electrical device, designed for voltage regulation in a single winding. By sharing a common winding for both primary and secondary circuits, it offers a compact, cost-effective solution for applications requiring a slight voltage adjustment.


A control transformer is crucial for voltage regulation in control circuits, providing stable voltage to control devices, ensuring safety and reliability. Its design isolates the control systems from power fluctuations, optimizing operational efficiency and protecting sensitive components.


Oil-immersed transformers use oil for cooling and insulation, enhancing durability and performance. Ideal for high-capacity applications, they ensure efficient heat dissipation and provide robust protection against environmental and electrical stresses.


An isolation transformer provides electrical isolation between its input and output, safeguarding against shock hazards and minimizing noise in sensitive devices. It's essential for protecting equipment and enhancing safety in electrical installations.
