10KV SH15/21/25 AMORPHOUS ALLOY ENERGY EFFICIENCY TRANSFORMER
Ultra-Low No-Load Loss: Reduces no-load loss by 60%–80% and no-load current by 89%, ideal for low-load or intermittent operation.
Advanced Core Design: Amorphous alloy with 3D wound core minimizes hysteresis and eddy current losses.
Strong Environmental Resistance: IP54 protection ensures reliable performance in harsh conditions like heat, humidity, and sandstorms.
Lower Operating Costs: Cuts annual operating costs by about 22.7% compared with S11 silicon steel transformers.
The SH15 type three-phase oil-immersed amorphous alloy core unloaded voltage regulating distribution transformer meets the Class 1 energy efficiency requirements of the standard for no-load and load losses. This means it is one of the most energy-efficient transformers currently available, with significant energy-saving effects.
Technical Features and Advantages: The SH15 amorphous alloy transformer uses an amorphous alloy core and a three-dimensional winding structure, offering the following core advantages:
* Extremely low no-load loss: No-load loss is reduced by 60%-80% compared to traditional silicon steel transformers, and the average no-load current is reduced by 89%, making it particularly suitable for scenarios with low load rates or intermittent operation (such as photovoltaic power stations and rural power grids).
* Materials and Structure: The high permeability and low magnetic flux density of amorphous alloy materials, combined with three-dimensional wound core technology, effectively reduce hysteresis loss and eddy current loss.
* Strong Protection Performance: Typically equipped with an IP54 protection rating, it can withstand harsh environments such as high temperature, high humidity, salt spray, and sandstorms.
Low operating costs: Compared with the S11 type silicon steel transformer, the annual operating cost of the SH15 type can be reduced by an average of about 22.7%.

Advantages of the Three-Phase Oil-Immersed Transformer Sh15-10KV
The silicon steel core is constructed from 0.18 ~ 0.3 mm oriented silicon steel sheets, precisely punched and stacked, ensuring excellent stability.
The coil is made of high-purity copper, with acetal enamelled wire for high voltage and oxygen-free copper conductors or copper foil for low voltage, enhancing resistance to short-circuits.
The Dyn11 connection symbol is adopted to minimize the impact of higher harmonics, providing strong resistance to unbalanced loads and improving power supply quality.
Vacuum oiling technology is applied to eliminate bubbles in the core, thereby ensuring reliable and consistent insulation performance.
