130-Ton Shell-Type Transformer Core for Brazil
A major Brazilian industrial transformer manufacturer, primarily responsible for producing transformers for domestic power grid modernization projects, handles large-scale projects with stringent requirements. They impose strict standards on the energy efficiency, mechanical strength, and service life of shell-type transformer cores.In April 2026, this client approached us through a referral from an existing customer and clearly outlined their procurement needs: 130 tons of shell-type transformer cores for use in power grid upgrade projects. The client required the products to comply with local Brazilian electrical standards and possess low losses, high stability, and excellent durability. Additionally, they requested professional technical support, comprehensive after-sales service, and a delivery timeframe of 35 days or less.
Upon receiving the request, we immediately assigned a technical team to liaise with the client, gaining a detailed understanding of local Brazilian electrical standards and specific project requirements. Taking into account the operating environment in South America, we optimized the design and manufacturing processes of the shell-type transformer cores to enhance product stability and durability.We provided the client with a detailed product proposal and technical specifications, proactively offered samples for testing, and assigned specialists to address their technical inquiries, ensuring the client fully understood the product’s advantages and suitability. After sample testing and proposal confirmation, the client signed a purchase contract with us.
Process Optimization to Enhance Transformer Core Compatibility
To meet the Brazilian client’s project requirements and local operating conditions, we customized and optimized the production process for the shell-type transformer cores.Regarding raw materials, we selected high-grade grain-oriented silicon steel, which offers high magnetic permeability, low losses, and high mechanical strength, effectively improving the energy efficiency and service life of the shell-type transformer cores. During production, we utilized automated cutting and laminating equipment to ensure precise core dimensions and tight lamination, thereby reducing magnetic leakage and eddy current losses and enhancing product energy efficiency.
To address the climatic conditions in South America, we have optimized the insulation and anti-corrosion treatment processes for the cores. By using high-quality insulation materials and anti-corrosion coatings, we have enhanced the cores’ resistance to moisture and rust, ensuring long-term, stable operation in humid and high-temperature environments.At the same time, we strictly adhere to local Brazilian electrical standards and the ISO quality management system. Every production step undergoes rigorous testing, and each batch of products is accompanied by a complete test report and certificate of conformity to ensure compliance with local usage standards. Throughout the production process, we provide timely updates on production progress to our clients, allowing them to monitor the status of their orders in real time.
Successful Delivery: Transformer Cores Lay the Foundation for South American Cooperation
After 35 days of efficient production and rigorous testing, the production, packaging, and loading of the 130-ton shell-type transformer core were fully completed.We assigned a dedicated international trade team to handle customs clearance and logistics, tracking the shipment’s progress throughout the entire process to ensure the goods were delivered smoothly to our Brazilian client. Upon arrival, the client organized a professional team to conduct a comprehensive inspection. Following testing and operational trials, they provided the following feedback: “We are highly satisfied with the product quality, delivery speed, and collaboration process. The shell-type transformer cores operate stably, feature low losses, and offer high reliability, fully meeting the standards of the power grid modernization project.”
The client has added us to their list of core suppliers and plans to expand our collaboration in the future, while also recommending us for core procurement in other power renovation projects in Brazil.With extensive experience serving the South American market, we provide professional technical support, customs clearance assistance, and after-sales warranty services to make procurement hassle-free for our overseas clients. This collaboration not only successfully fulfilled the delivery requirements but also laid a solid foundation for our expansion into the South American market. Moving forward, we will continue to optimize our products and services to provide South American clients with even higher-quality shell-type transformer cores.
