SBH25 Amorphous Alloy Tridimensional Toroidal Core Oil-Immersed Transformer
The SBH25 combines two cutting-edge technologies: amorphous alloy core material (25μm ultra-thin strip, excellent magnetic permeability) and tridimensional toroidal structure. The result is a transformer with up to 80% lower no-load loss compared with conventional silicon steel products — the pinnacle of energy-saving distribution transformer technology.
Product Specifications
Product Description
Product Overview
The SBH25 Amorphous Alloy Tridimensional Toroidal Core Oil-Immersed Transformer represents the peak of modern energy-saving technology in power distribution. By utilizing an amorphous alloy magnetic core combined with a tridimensional wound toroidal core structure, this transformer achieves an extraordinary reduction in no-load losses (up to 70% lower than traditional silicon steel transformers) and delivers ultra-silent, highly efficient operation over a long service life.
Key Features
- Amorphous Alloy Core: Eliminates crystalline structure in the core metal, leading to extremely low magnetic hysteresis and eddy current losses.
- Tridimensional Wound Toroidal Core: Three-dimensional, symmetrical three-phase balanced layout ensures balanced magnetic circuits, minimized leakage, and reduced noise.
- Hermetically Sealed Tank: Corrugated oil tank structure prevents contact between transformer oil and air, completely eliminating moisture absorption and oil aging.
- Superior Heat Dissipation: Natural oil convection combined with high-strength corrugated radiators ensures efficient thermal management.
- Eco-Friendly & Energy Saving: Helps operators reduce carbon emissions and operational energy overhead, meeting the highest eco-design standards.
