Advancing Transformer Production in the AI Era: AIMStek Supports AEC’s Intelligent Production Line

Customer Background

Founded in 1968 and listed in 1994, Allis Electric Co., Ltd. (AEC) is a leading Taiwanese manufacturer in the power equipment industry. Its business covers high- and low-voltage switchgear, power distribution equipment, and various types of transformers.

As AI infrastructure and data center construction drive growing demand for power equipment, AEC is expanding its second transformer plant in Yangmei to strengthen its production capacity. The new facility requires not only reliable manufacturing capabilities but also efficient material handling, seamless process coordination, and effective production management.

Project Challenges

Heavy-load handling requirements. Oil-immersed transformers are large and heavy, with finished units weighing over 800 kg. This places demanding requirements on conveying equipment, load capacity, and handling fixtures.

Complex production workflows. Transformer manufacturing involves multiple critical processes, including active-part assembly, vacuum drying, tank insertion, vacuum oil filling, settling, and electrical testing. These processes require coordinated lifting, conveying, and material handling to maintain an organized production flow.

Digital production management. As production automation advances, systematic management of production orders, process flow, equipment data collection, and production traceability becomes increasingly important.

Solution

AIMStek developed a production line solution tailored to the manufacturing processes and operational requirements of oil-immersed transformers, integrating automated intralogistics, heavy-load conveying and handling fixtures, and digital production management.

1. End-to-End Automated Conveying and Lifting

The solution integrates flexible KBK overhead lifting systems, roller conveyors, and rotary conveyors to connect key production areas, including active-part assembly, tank insertion, cover pre-assembly, testing, and finished-product unloading. Material carts and tooling pallets support material transfer and line-side buffering, establishing an automated intralogistics system across the production workflow.

2. Heavy-Load Conveying and Handling Fixtures

Designed for the large dimensions and heavy weight of rod-type and pad-mounted oil-immersed transformers, the conveying lines and tooling pallets are designed for rated loads in the 1,000 kg class. The system accommodates finished transformers weighing over 800 kg, supporting reliable handling throughout the production process.

3. Production-Line MES System

A lightweight Manufacturing Execution System (MES) integrates production management, process flow control, and data collection. Its functions cover production orders, process and operation management, bills of materials (BOM), material and equipment management, as well as production dashboards, reports, and relevant process traceability. This enables coordinated management of production tasks, shop-floor operations, and production data.

Customer Value

Supporting New Plant Capacity Development

Designed around the production requirements of AEC’s new Yangmei facility, the automated production line establishes the infrastructure needed to support manufacturing operations and future capacity ramp-up, helping AEC strengthen its production capabilities in response to growing market demand.

Improving Production Flow and Process Coordination

The coordinated application of automated conveying, lifting, and line-side buffering supports the movement of heavy transformers between production stages. This provides a structured foundation for smoother material flow and better coordination across manufacturing processes.

Strengthening Digital Production Management

The lightweight MES system brings production tasks, process flow, shop-floor operations, and relevant equipment data into a unified management framework. It provides data support for production progress monitoring, process management, and quality traceability, laying the groundwork for more systematic and transparent production management.

Growing demand for power driven by AI infrastructure and data center expansion is creating new opportunities for transformer and power equipment manufacturers. Responding to this demand requires more than additional production equipment—it also calls for coordinated intralogistics automation and digital production management.

Through the integration of automated conveying and lifting, heavy-load handling, and a lightweight MES system, AIMStek supports the development of AEC’s new Yangmei production line. The project also offers a practical reference for power equipment manufacturers seeking to advance production automation and digital shop-floor management.
