Transformers are essential components in electrical and automation systems, designed to transfer electrical energy between circuits through electromagnetic induction. They are widely used in power distribution, voltage regulation, and isolation applications. Common types include power transformers, distribution transformers, and instrument transformers. Key products in this category may include step-up/step-down transformers, autotransformers, toroidal transformers, and current transformers. These devices feature varying voltage ratios, power ratings, and cooling methods (oil-immersed or dry-type). Industrial-grade transformers often incorporate protective features like thermal overload protection and noise reduction. They serve critical functions in machinery, control systems, and power supply networks across manufacturing and automation sectors.
