Full-sealed Distribution Transformer •Introduction To Products 01) SH15 series amorphous alloy full-sealed transformer is a novel energy-saving material made. 02) With a fast and abrupt-solidification process and the metal atoms arrange in a disordered amorphous state. 03) Its structure completely different from crystal of silicon steel makes it easily magnetized and de-magnetized. 04) When this novel material is used in transformer core, a running transformer may be easily subjected to 120 cycles/second of magnetizing and de-magnetizing process and thus no-load loss of the core is greatly reduced. 05) If the said alloy is used in oil-immersed transformer, escape of harmful gases such as CO2, SO2 and NOX may be reduced and thus it is known as “ green material “ of 21st century. 06) A model SH15 amorphous alloy product adopts a single-frame or three-phase five-legged spiral core. 07) The core is clamped with sheet-formed frame structure and the low-voltage coil is of a foil winding type so as to render a low loss and a high short-circuit withstand. 08) It has advanced and rational structure and its overall performances reach international advanced level. •Main Function And Features 10kV Amorphous Alloy Full-enclosed Distribution Transformer 630 kva transformer 01) SH15 series amorphous alloy full-sealed transformer is an epoch-making technology and trans-century “Green ” product . 02) The iron base amorphous alloy core has high saturation magnetic induction intensity. 03) Low loss (equivalent to 1/3-1/5 of silicon sheet). 04) Low corrective force. 05) Low excitation current. 06) Good temperature stability. 07) Compared with S9 series with silicon sheet , the no-load loss of the transformer with amorphous alloy core is reduced by 70%-80% , no-load current reduced by 20%. 08) Environmental protection. 09) High efficient transformer. 10) Core is with three phases, four frames, and 5 columns. 11) Use Dyn11 to connect other parts, reduce the influences by network wave, improve the power supply. 12) Oil box is sealed, free from maintenance. Box is sealed, free from maintenance. 13) Empty loading loss is only 20% of S9 type transformer. •Application Range Widely used in city network, petrochemical industry, metallurgy, textile, or the mines or companies where are under the condition of high humidity or with the difficulty in maintenance.
