Project Overview
The transformer production line is located in the soon-to-be-built Plant No. 5 of Shunte Electric Equipment Co., Ltd. It is mainly used for the production of dry-type transformers with voltage levels of 35kV and below, and finished product weights not exceeding 25 tons. The entire production and material transfer process for dry-type transformers is planned across two floors of Plant No. 5. Automated logistics and handling equipment such as AGV automatic conveying systems, RGV automatic conveying systems, and gantry robots are deployed to realize automation in logistics handling throughout the production process, aiming to reduce manpower and improve efficiency.
Construction Scope
This is a turnkey project including complete design, manufacturing, installation, commissioning, training, and delivery. Highlights of the project include:
• Full-process, full 3D digital modeling + process optimization
• 5G + all-optical network + full-process information system integration
• Equipment interconnection + 100% data collection + digital twin
• Information data + industrial cybersecurity + efficient operation and maintenance
Ø Construction of the automated production line
The line integrates and implements the entire process of dry-type transformer manufacturing, including raw material/semi-finished product warehousing, inner mold assembly, winding, outer mold assembly, casting, curing, mold removal, automatic coil cutting and grinding, transformer final assembly, and internal logistics handling. In addition, the design and construction of the workshop’s air conditioning system and the personnel/material air shower dust removal system are also included.
