S22 Oil-Immersed Silicon Steel Tridimensional Toroidal Core Transformer
The S22 series adopts a patented “spatial tridimensional triangular” toroidal core structure, achieving symmetrical three-phase magnetic circuits. Compared with conventional stacked-core transformers, it delivers 25–40% lower no-load loss, 5–10dB noise reduction, and superior short-circuit resistance — making it the preferred choice for urban grid modernization and industrial distribution.
Product Specifications
Product Description
Product Overview
The S22 Oil-Immersed Silicon Steel Tridimensional Toroidal Core Transformer is a highly reliable, high-performance distribution transformer designed for three-phase AC power networks. Featuring an innovative three-dimensional wound core structure made of high-quality cold-rolled grain-oriented silicon steel, this transformer offers excellent magnetic properties, reduced material consumption, and lower operational noise, making it a robust and economical choice for standard power distribution applications.
Key Features
- Tridimensional Wound Core Structure: Seamless wound core rings arranged in a 3D equilateral triangle configuration eliminate air gaps, optimizing core magnetic efficiency.
- High-Quality Silicon Steel Core: Constructed using premium grain-oriented silicon steel sheets, guaranteeing exceptional flux density and minimal losses.
- Fully Sealed Maintenance-Free Design: Corrugated steel tank with expansion and contraction capabilities accommodates oil volume changes, preventing oil degradation.
- High Short-Circuit Resistance: The compact cylindrical winding and solid triangular core clamping structure provide unparalleled resistance to mechanical forces.
- Lower Noise & Low No-Load Current: Symmetrical core design naturally reduces magnetostriction and operating vibration, minimizing auditory impact.
