 S11-MRL/MR tridimensional/planar Toroidal-Core power transformer
Home >> Product Show
Product Overview:
This series is widely used in 10KV and 6KV transmission and distribution systems, with Toroidal-Core in tridimensional/planar structure (selected by the user), no-load loss for 30% lower than S9 series on average, no-load current for 60 - 80% down and noise decreased by 30 - 40%, along with remarkable energy saving. Fully sealed with corrugated tank, the product features low loss and noise, good appearance, excellent performance, maintenance-free, long life and other advantages, known as new generation with high-tech, high-performance, energy-saving and environmental protection in similar products.
Product Features:
Core material refers to 23ZH100 quality high permeability grain oriented cold-rolled silicon steel sheet manufactured by Nippon Steel Corp, in the process where silicon steel strip is wound into a polygonal closed core, with no seam and gap in magnetic circuit, and therefore, it can feature low loss and noise, all mechanized core processing, as well as improved product quality and stability. Tridimensional Toroidal-Core transformer uses symmetrical three-phase 3D structure, completely symmetrical in three-phase core magnetic circuit, resulting in magnetic reluctance reduction, significantly decreased no-load current and loss as well as lower operating noise.
