Features
◉ Energy-efficient and stable operation:R-core transformers have low losses and temperature rise. Their simple structure, commonly in a horizontal design, allows for a compact form, making them suitable for high-density installations. The windings are circular, reducing the average turn length by 6%-10%, resulting in low copper losses.
◉ Superior materials:The core of the R series transformers uses high-permeability cold-rolled silicon steel strips, offering small hysteresisexpansion, noise reduction, reduced weight, and excellent magnetic conductivity.
◉ Compact size and low noise:At the same power rating, R-type transformers are more compact than traditional TD series transformers, making them suitable for industrial portable equipment, intelligent control cabinets, and other applications. Additionally, they produce low operating noise, meeting the needs of various industrial applications.
