As Nancal Electric takes on a growing number of major projects and pioneering R&D and manufacturing tasks in sectors such as nuclear power, defense, chemicals, LNG, and energy storage, the company has completed a thorough upgrade of its Lingang manufacturing base. This upgrade includes enhancements to both hardware and software to create a more standardized and specialized manufacturing environment.
A new production line for three-proofing coating equipment has been introduced, utilizing UV automatic coating technology. This advancement significantly boosts the circuit boards' ability to withstand harsh conditions like salt spray, humidity, and dust. Additional testing equipment has been acquired, including a spectrophotometer, film thickness gauge, electron microscope, and high-low temperature alternating thermal test chamber. These upgrades enhance testing standards and experimental capabilities, allowing for comprehensive verification of product reliability.
Three-Proofing Coating Equipment
2,000-square-meter fire-resistant cleanrooms have been constructed for the assembly and testing of water-cooling and air-cooling power cells. All cleanrooms are equipped with air conditioning and other facilities to ensure a dust-free, temperature-controlled, and electrostatic-free environment. The assembly process now uses a drum-type production line with industrial flat-panel computers, improving production efficiency. The factory floor has been reinforced with an ultra-wear-resistant polyurethane treatment to optimize the working environment and ensure product quality.

Power Cell Assembly Line
New 4,200-square-meter stereoscopic warehouses have been built, featuring multiple cranes, flexible hoists, and cantilever cranes to significantly enhance storage and transportation efficiency within the facility.
Stereoscopic Warehouse
Nancal Electric has also developed automated testing systems for circuit boards, power units, and complete machines, achieving full test automation. The implementation of ERP and MES systems has further digitalized management processes.
The Lingang manufacturing base now spans approximately 20,000 square meters, with an annual production capacity of 1,600 VFDs, a maximum power cell testing capability of 3,000A, and a full-power testing capacity of 180MVA. Nearly 200 testing and inspection items are covered.
To date, Nancal Electric has produced over 150 large-capacity water-cooling medium-voltage VFDs, totaling more than 4,500MVA, serving 28 countries worldwide. Notably, the world’s largest 130MVA medium-voltage VFD (March 2022, ISTIS20220138SH) and the LNG industry’s largest 86.6MVA medium-voltage VFD (January 2023, ISTIS20222438) have both been successfully delivered.
“Quality drives customer value.” Nancal Electric remains committed to technological leadership while investing in infrastructure, enhancing manufacturing and delivery capabilities, and consistently delivering high-quality products and services to its customers.
