Engineering Voltage, capacity, impedance, cooling method, and installation environment matching.
Production Core, coil, insulation, assembly, drying, oil treatment, and process inspection.
Testing Routine electrical checks and delivery inspection before shipment.

Manufacturing Capability

From project data to ready-to-install transformer

01

Electrical Design Matching

Capacity, voltage, loss level, impedance, vector group, and protection requirements are confirmed according to site load and grid conditions.

02

Controlled Production

Core stacking, coil winding, insulation treatment, assembly, drying, and oil filling are managed with process records.

03

Routine Factory Testing

Key electrical performance, insulation strength, ratio, resistance, no-load loss, load loss, and appearance checks are completed before shipment.

04

Project Delivery Support

Packaging, documentation, installation guidance, spare parts, and after-sales response support stable commissioning on site.

Quality Route

Each transformer follows a clear inspection path

We put quality control into the manufacturing route instead of leaving it only to the end. This helps reduce delivery risk and keeps project schedules easier to manage.

Material

Silicon steel, copper or aluminum conductor, insulation materials, oil, and components are checked before use.

Process

Winding, insulation, assembly, drying, and sealing are inspected through production records.

Testing

Routine electrical tests and visual checks are completed before packing and delivery.
