Product Description
SH15 series amorphous alloy full-sealed transformer is an epoch-making and trans-century “Green” product. The iron base amorphous alloy core has high saturation magnetic induction intensity, low loss (equivalent to 1/3-1/5 of silicon sheet), low corrective force and low excitation current and good temperature stability.
The amorphous alloy is a novel energy-saving material made with a fast and abrupt-solidfication process and the metal atoms arrange in a disordered amorphous state and its structure completely different from crystal of silicon steel makes it easily magnetized and de-magnetized. 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. 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 21 century.
A Model SH-15 amorphous alloy product adopts a single-frame or three-phase five-legged spiral core. The core is clamped with sheet-formed 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. It has advanced and rational structure and its overall performances reach international advanced level.

Frequently Asked Questions (FAQ)
What is the core advantage of the SH15 series transformer?
The main advantage is its use of amorphous alloy core, which reduces no-load loss by 75% to 80% compared to traditional S9 series silicon steel transformers, resulting in significant energy savings.
Why is this product described as a "Green Material" transformer?
Because it significantly reduces power consumption and the generation of harmful gases such as CO2, SO2, and NOX, helping to mitigate the greenhouse effect and environmental pollution.
What are the standard operating conditions for this transformer?
It is designed for altitudes below 1000m with ambient temperatures ranging from a minimum of -25°C to a maximum of +40°C. Custom units can be provided for special environments.
How does the amorphous alloy core handle harmonic resistance?
The amorphous core maintains low iron loss and low excitation current even when passing through high-frequency magnetic flux, preventing core saturation and providing excellent harmonic resistance.
Is the SH15 transformer maintenance-free?
Yes, the fully sealed structure utilizes vacuum drying, vacuum oil filtering, and corrugated oil tanks without an oil conservator, making it essentially maintenance-free and pollution-free.
What is the composition of the amorphous alloy material?
The alloy strip typically contains approximately 78% - 81% iron, 13.5% boron, and 3.5% - 8% silicon, along with trace metal elements like nickel and cobalt.
