The amorphous alloy core reduces the energy consumed whenever the transformer is energized, even when little or no load is connected.
Reduced no-load loss helps utilities and facility owners save energy throughout the transformer’s service life.
The hermetically sealed tank limits contact between the insulating oil and outside air, helping prevent moisture ingress and oil oxidation.
The sealed tank, corrosion-resistant coating and oil-immersed insulation system support stable operation in outdoor distribution networks.
The fully sealed structure eliminates the need for a conventional conservator and reduces routine oil-related maintenance requirements.
Capacity, voltage, winding material, vector group, taps, impedance, oil type, accessories and enclosure can be customized.
DINGXIN SH15 sealed amorphous alloy transformers are designed for energy-efficient medium-voltage distribution systems.
Available from 30 kVA to 2,500 kVA, the standard configuration steps 10 kV down to 0.4 kV. The fully oil-filled and hermetically sealed tank protects the insulating oil from external moisture and air, helping reduce oxidation and routine maintenance.
The amorphous alloy core uses an ultra-thin magnetic ribbon approximately 0.027 mm thick. Its high electrical resistivity and low magnetization requirements significantly reduce core losses, making the transformer especially suitable for networks that remain energized continuously or operate with long periods of light load.

High pressure transformer, use analysis software and calculation and validation procedures to the transformer core, winding. implement body, lead, fuel tanks, etc, Parts of the optimal design and carry on the omni - directional validation, ensure product performance.

Amorphous alloy is a soft magnetic material primarily composed of iron with elements such as silicon and boron.
Unlike conventional silicon-steel laminations, the material has no regular crystalline structure. Its ultra-thin ribbon and high electrical resistivity help reduce eddy-current and hysteresis losses.
Because amorphous metal is sensitive to mechanical stress, DINGXIN carefully controls core handling, clamping, winding support and final assembly to avoid reducing its magnetic performance.
DINGXIN amorphous alloy transformers are suitable for:
They are especially valuable where the transformer remains energized for 24 hours per day but does not always operate at full load.
Customers can specify:
DINGXIN manufactures customized transformers and substations for utility, commercial, industrial and renewable-energy projects.
