R Core Three Phase Power Transformers with 20VA Rated Power

Features:

The adoption of an R-type core—made from grain-oriented high permeability silicon steel strip with an uncut, round cross-section—represents a revolutionary breakthrough in transformer technology. Compared to E1, C, and toroidal transformers, R-type transformers offer superior performance and higher reliability, characterized by their compact size, light weight, high efficiency, and minimal leakage magnetic flux.

Compact Size & Light Weight:
R-type transformers utilize an uncut wound core constructed from high-quality materials, resulting in a smaller volume and lighter weight. With standardized product series available, they are easier to install and select for users.

High Efficiency:
Because the core is uncut, core losses are minimal. Coupled with the use of premium materials and a compact structure that minimizes the distance between the core and windings, efficiency can reach over 90%.

Low Leakage Magnetic Flux:
The R-type transformer's core has no air gaps and features balanced winding distribution, leading to very low leakage magnetic flux. No special anti-leakage measures are required in design.

Low Heat Generation & Noiseless Operation:
Manufactured using high-quality, low-loss materials, these transformers feature a uniformly round core cross-section and short average turn length for windings. This results in very low resistive losses and heat generation. Since the core is uncut, magnetostrictive stress is easily absorbed, ensuring quiet operation in practical applications.

Low Excitation Current:
With its rational design, the R-type transformer exhibits low core losses, minimal heat generation, small excitation current, and energy savings.

Compliance with Safety Standards:
Its unique design separates primary and secondary coil frameworks, providing excellent insulation performance. It meets various international and national safety standards. Additionally, temperature fuses and electrostatic shielding can be installed upon customer request.
