What are the performance characteristics of R-type transformers?

R-type transformers exhibit exceptional performance in various applications due to their unique structure and material selection. The following are the main performance characteristics of R-type transformers:

Peculiarity

●Compact Size and Light Weight:

R-type transformers featurean uncut ring-shaped core, which significantly reduces the transformer’s volume. The core is made from high-permeability silicon steel sheets, further optimizing the size and weight of the transformer. The absence of traditional cut lines minimizes material waste, making the transformer more compact and suitable for applications with limited space.

●High Efficiency:

The lack of cuts in the core significantly reduces core losses (also known as iron losses). Additionally, the use of high-quality materials and a compact design minimize the distance between the core and the windings. This design can significantly enhance the transformer’s efficiency, typicallyexceeding 90%. Low core losses and high efficiency mean that the transformer operates with higher energy conversion efficiency under load conditions, reducing energy waste.

●Low Leakage Flux:

The core structure of R-type transformerslacks magnetic gaps, and the winding process is very uniform, resulting in minimal leakage flux. This design eliminates the need for additional measures to prevent flux leakage, thus improving the overall performance and stability of the transformer. Low leakage flux translates to higher magnetic energy utilization and better electromagnetic compatibility.

●No Noise and Low Heat Generation:

The use of an uncut core,high-permeability silicon steel sheets, and a uniform circular cross-section with continuous winding reduce resistance losses and heat generation. More importantly, the absence of a cut core effectively absorbs magnetostriction stresses, significantly reducing noise. This design ensures that R-type transformers operate almost silently, making them ideal for applications with strict noise requirements.

●Low Magnetizing Current:

Due to its efficient design, R-type transformers exhibit low core losses and minimal heat generation, resulting in relatively low magnetizing current (the current required when the transformer is under no load). This characteristic not only enhances the overall energy efficiency of the transformer but also reduces the load on the power supply, thereby lowering operating costs.

●High Safety Factor:

R-type transformers feature a unique design that separates the primary and secondary winding structures, ensuring excellent insulation performance. The core framework uses flame-retardant materials that meet various international safety standards. This design not only enhances the transformer’s insulation performance but also improves its safety in diverse environmental conditions.

In summary

In summary, R-core transformers, with their compact size, high efficiency, low leakage flux, noiseless operation, low magnetizing current, and high safety factor, are widely used in applications requiring high performance and reliability, such as electronic devices, industrial control systems, and audio equipment.
