Guangdong NRE, with 30 years of experience in manufacturing EI transformers, not only ensures top-tier product quality but also consistently drives technological advancements to offer more competitive solutions to customers.

The Origins of EI Transformers

The name "EI transformer" comes from the shape of its core, which is composed of an E-shaped and I-shaped core. This unique design effectively reduces magnetic leakage and enhances electromagnetic conversion efficiency. The earliest EI transformers emerged during the proliferation of electrical equipment and gradually found applications in household appliances, industrial equipment, and power systems. Over decades of development, EI transformers have evolved into a key player in power conversion technology.
