High-precision machinery designed for local transformer factories to reduce no-load losses and meet BPDB specifications.
Understanding the transition from traditional grid infrastructure to energy-efficient power networks in South Asia.
Bangladesh is undergoing one of the fastest electrical grid expansions in South Asia. Led by agencies such as the Bangladesh Power Development Board (BPDB), the Dhaka Electric Supply Company (DESCO), and the Rural Electrification Board (BREB), the nation is aggressively upgrading its transmission and distribution networks. This modernization effort targets rural electrification and heavy industrial hubs alike, requiring millions of new distribution and power transformers.
Historically, local transformer manufacturers relied on imported, pre-assembled laminated cores or manually stacked cores. However, rising tariffs, transportation risks, and the imperative to reduce grid losses have forced local manufacturers in industrial zones like Gazipur, Chittagong, and Narayanganj to build in-house manufacturing capabilities. To stay competitive, factories must import advanced core processing machinery.
Under the national energy policy guidelines, the government is strictly enforcing regulations to minimize transmission losses. Traditional stacked cores exhibit high no-load losses due to air gaps and overlapping joints. Consequently, the demand has shifted dramatically toward 3D wound cores (triangular cores) and amorphous alloy cores.
Our company specializes in delivering state-of-the-art core machines that empower Bangladeshi transformer manufacturers to produce high-efficiency cores locally. By processing raw grain-oriented silicon steel (CRGO) and amorphous alloy ribbons in-house, local manufacturers can reduce no-load losses by up to 30% to 75%, aligning their output directly with the strict specifications of BPDB and international utility tenders.
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/workshops on demos and optimizations, finally developing a transformer with 30% lower temperature rise and 15-year lifespan, winning high client recognition."
Providing technical information gain on manufacturing methodologies, magnetic characteristics, and industrial implementation.
Unlike traditional flat cores, 3D triangular cores consist of three symmetrical rings arranged in a three-dimensional space. The magnetic path is completely continuous with no joints, eliminating high-reluctance overlaps. Our automatic winding machine feeds and winds silicon steel strip continuously under precise PLC control, ensuring tight tension and minimal magnetostriction noise.
Amorphous alloy ribbon is extremely thin (approx. 25–30 μm) and highly brittle compared to standard cold-rolled grain-oriented (CRGO) steel. Cutting it requires extreme precision to avoid micro-cracks and burrs, which degrade magnetic properties. Our high-precision CNC shearing machines utilize specialized carbide blades and patented feeding mechanisms to deliver clean, stress-free cuts at high volume.
The winding process introduces mechanical stresses that disrupt the magnetic domain structure of CRGO steel or amorphous alloy ribbons, increasing core losses. Our specialized vacuum annealing furnace provides a controlled nitrogen atmosphere with precise temperature control loops. This process restores original magnetic permeability, ensuring low hysteresis losses.
Before establishing a manufacturing line in Bangladesh, plant managers must evaluate the core material handling properties. Here is an engineering comparison table compiled by Shuhong Technical Department:
| Parameter / Feature | 3D CRGO Wound Core | Amorphous Alloy Core | Traditional Stacked Core |
|---|---|---|---|
| No-Load Loss Reduction | Moderate-High (20% - 30%) | Extreme (70% - 80%) | Baseline (0%) |
| Raw Material Thickness | 0.23 mm - 0.30 mm | 0.025 mm - 0.03 mm | 0.23 mm - 0.35 mm |
| Core Assembly Method | Continuous Winding on Winding Machine | CNC Shearing + Assembly Table | Manual / Auto Sheet Stacking |
| Required Machinery investment | Winding Machine + Curve Cutter + Annealing | CNC Shearing + Assembly + Annealing | CNC Slitting + Cross-Cutting Line |
| Vibration & Noise Levels | Low (-5 to -10 dB) | High (requires special damping) | Moderate |
