High-efficiency, low-loss core machinery engineered for PT PLN distribution networks, renewable integration, and high-performance industrial power substations.
As the largest economy in Southeast Asia, Indonesia is undergoing an unprecedented modernization of its power transmission and distribution network. Under the national utility provider PT PLN's long-term electricity supply plan (RUPTL), the Indonesian government has committed to upgrading regional power grids, integrating renewable energy hubs in Kalimantan, Sumatra, and Sulawesi, and reducing aggregate distribution losses across Java-Bali. Achieving these ambitious clean energy targets requires a paradigm shift in local transformer manufacturing—transitioning from legacy, high-loss stacked core configurations to high-efficiency 3D wound cores and amorphous alloy cores.
For transformer manufacturers and industrial suppliers operating within the Indonesian archipelago, sourcing cutting-edge core processing machinery is not merely a operational choice, but a regulatory and competitive necessity. Core loss accounts for a substantial percentage of continuous grid inefficiencies. By utilizing high-precision silicon steel slitting lines, automated 3D core winding machines, and controlled-atmosphere vacuum annealing furnaces, local manufacturers can produce transformers that minimize no-load losses by up to 60-80% compared to traditional configurations.
Additionally, the Indonesian Ministry of Industry enforces stringent TKDN (Tingkat Komponen Dalam Negeri) local content certification guidelines. To remain competitive in PLN public procurement bids, transformer suppliers must set up high-degree local production facilities. Investing in state-of-the-art CNC core shearing, winding, and metal processing lines ensures that production is localized in compliance with TKDN regulations while maintaining global quality benchmarks.
Deeply Developing the Machinery Industry, Empowering the Future of Energy.
On the shores of the picturesque Taihu Lake lies Wuxi, known as the "Land of Fish and Rice." This beautiful land has nurtured countless enterprising enterprises, with Wuxi Shuhong Machinery Technology Co., Ltd. standing out among them. Since its establishment in 2018, Shuhong Machinery has consistently prioritized technological innovation and quality service, steadily advancing in the fields of electrical and plastic machinery, becoming a high-tech enterprise with both strength and reputation.
Shuhong Machinery originated from its founder’s insight into machinery manufacturing. With over a decade in the industry (from front-line technical roles to management), the founder witnessed domestic machinery shift from "following" to "running alongside" global peers, and sensed the need for energy-efficient, intelligent upgrades.
During a State Grid project exchange, the founder found traditional transformers flawed in temperature control and service life (harming power stability, raising costs) and noted new energy’s higher equipment demands—thus focusing on R&D and manufacturing of high-efficiency, energy-saving transformers.
Overcoming funding and technical hurdles, the team worked day and night in labs and workshops on demos and optimizations, finally developing a transformer core winding and manufacturing line that achieves 30% lower temperature rise and a 15-year lifespan, winning high client recognition across domestic and international markets.
After years of development, Shuhong Machinery has established a complete R&D-design-production-sales-service industrial chain, with a professional engineering team and modern factories ensuring product quality. Focused on technical innovation, the company leads in insulation and temperature control; its products have passed State Grid and international certifications. It has supplied over 2,000 substations, boosting energy stability and grid efficiency.
The manufacture of high-efficiency silicon steel and amorphous alloy cores involves an array of consecutive mechanical and thermal operations. Any slight deviation in shear angles, stress accumulation, or thermal annealing profiles will severely degrade the magnetic properties of the raw silicon steel. Below is our complete production sequence, managed via automated, synchronized PLC controls:
By enforcing precise tolerances at the Material Cutting and Winding stages, we prevent micro-fractures in the crystalline structure of the silicon steel. The subsequent Annealing process is performed in an oxygen-depleted vacuum to release the internal mechanical stresses introduced during slitting and winding. Finally, Testing ensures that the final core complies with international IEC and Indonesian SNI standards before shipping.
Shuhong Machinery adheres to the team management philosophy of "People-Oriented, Collaborative Innovation", taking an excellent team as its success foundation.

Staying True to Our Original Aspiration and Striving for Greater Goals.
Looking forward, Shuhong Machinery will uphold its business philosophy of "People-oriented, Integrity-driven, Collaborative Innovation, and Quality First." It will deepen focus on electrical and plastics machinery, boost R&D investment to strengthen core technologies, and launch more efficient, energy-saving and intelligent products.
The company will also expand domestic and international markets, cooperate with industry leaders, strive to build an internationally competitive machinery brand, and further contribute to China’s machinery manufacturing and energy sector development. As the ASEAN energy landscape undergoes a fast transition towards decentralized solar photovoltaics, wind energy integration, and micro-grid distribution, our R&D roadmap is heavily aligned with producing ultra-low loss cores capable of mitigating harmonics and electrical stress associated with intermittent renewable feeds.
We guarantee flawless machinery commissioning, regulatory compliance, and rapid shipping to major industrial hubs in Indonesia and worldwide.
Our core manufacturing machines are fully optimized to help local Indonesian factories conform to SNI (Standar Nasional Indonesia), SPLN standards, and achieve competitive TKDN content ratios.
Offering direct sea freight solutions to major ports including Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), Belawan (Medan), and Soekarno-Hatta (Makassar) with full customs handling.
We support smart grid factories with comprehensive remote commissioning, PLC program upgrades, real-time diagnostic systems, and specialized on-site technician dispatches.
"Implementing Wuxi Shuhong’s automated 3D roll core winding systems allowed our production facility in West Java to cut no-load losses by 35% compared to our legacy stacked core lines. Our factory successfully cleared the strict PT PLN audit."
"The CNC silicon steel slitting equipment we purchased in 2021 has run continuously with zero structural misalignment. The edge quality and lack of burrs have vastly improved our magnetic core efficiency."
