Transformer Manufacturing Equipment Solutions for Every Application
From distribution transformers to ultra-high-voltage power transformers, SIDA delivers the complete equipment portfolio that covers every stage of transformer production — winding, core stacking, insulation processing, drying, vacuum treatment, and busbar fabrication.
Equipment Solutions for Every Transformer Application
SIDA machines are engineered to meet the specific process demands of each transformer category, ensuring consistent quality from coil winding to final assembly.
Power Transformers
High-voltage and extra-high-voltage power transformers require precision layering and controlled tension. SIDA vertical and horizontal winding machines, combined with automatic HV winding systems, deliver accurate coil geometry for 110kV–800kV classes.
Distribution Transformers
For high-volume distribution transformer production, SIDA foil winding machines and core stacking tables enable rapid changeovers and consistent lamination. Ideal for utilities and OEMs producing 10kV–35kV units at scale.
Dry-Type Transformers
Dry-type transformers demand clean, moisture-free insulation. SIDA vacuum drying and vapour phase drying systems remove residual moisture before resin casting, while static mixing vacuum casting ensures bubble-free insulation.
Oil-Immersed Transformers
Oil-immersed units require rigorous moisture removal and vacuum oil filling. SIDA vacuum drying equipment and vacuum oil filling systems ensure IEC-compliant moisture readings and reliable dielectric performance.
Reactors & Inductors
Shunt reactors and series inductors require precise gap control and uniform winding tension. SIDA core coil wind machines and adjustable winding mandrels maintain geometric accuracy for high-reactance designs.
HVDC Converter Transformers
HVDC converter transformers operate under extreme electrical stress. SIDA insulation parts processing centers and CNC step-wood machines machine pressboard and insulation components to micron-level precision for reliable dielectric performance.
From Raw Material to Finished Transformer
SIDA equipment covers all seven critical stages of transformer manufacturing, enabling turnkey production line design.
Coil & Layer Formation
Precision coil winding machines: vertical, horizontal, foil and automatic HV types. Ensure accurate layering for transformer coils.
Lamination & Stacking
Silicon steel cutting, stacking and binding equipment for transformer cores. High-efficiency production with precise lamination.
Compaction & Geometry Control
Coil pressing, shaping and lifting tools for transformer assembly. Ensure proper compaction, geometric accuracy and safe handling.
Dielectric Parts Machining
CNC cutting, milling and forming machines for pressboard and insulation parts. Precision machining for reliable dielectric performance.
Moisture Removal & Curing
Industrial ovens and drying systems for transformers and reactors. Uniform heating, energy efficiency and safe insulation curing.
Impregnation & Oil Filling
Vacuum drying, oil filling and casting systems for transformers. Ensure moisture removal and bubble-free insulation processing.
LV/HV Connection Fabrication
CNC punching, bending and cutting machines for copper and aluminum busbars. Accurate patterns, precise angles and clean edges.
Trusted by Transformer Manufacturers Worldwide
Real outcomes from real production lines. SIDA equipment is running in transformer factories across 45+ countries.
"We deployed SIDA winding machines in our 110kV power transformer line. Setup changeover time dropped by approximately 30%, and coil layering consistency improved noticeably. The automatic HV winding machine is now central to our high-voltage production."
"After installing the SIDA silicon steel slitting and core cutting line, our lamination scrap rate fell under 2%. The precision stacking table and binding machine keep our core assembly tight and square, even at high throughput."
"For our oil-immersed distribution transformers, SIDA's vapour phase drying plus vacuum oil filling integration means moisture readings consistently meet IEC standards. The drying cycle time is also shorter than our previous batch process."
