As a leader in sustainable power equipment, CHH Power prioritizes energy efficiency in transformer manufacturing. By focusing on two core areas—high-quality material adoption and innovative design-process optimization—the company significantly reduces transformer energy loss, aligning with global low-carbon energy goals. Below is a detailed breakdown of CHH Power’s key energy-saving practices.
1. High-Quality Material Adoption: The Foundation of Low-Loss Transformers
Transformers rely on electromagnetic induction to adjust grid voltage, with silicon steel sheets (for cores) and electromagnetic wires (for windings) as their primary materials. CHH Power recognizes that the quality of these two components directly determines the transformer’s loss characteristics, particularly focusing on minimizing no-load loss—a constant energy dissipation from the core during operation, independent of load rate and unavoidable but reducible through material upgrades.
- Silicon Steel Sheet Upgrades: CHH Power pioneered the adoption of high-performance cold-rolled grain-oriented silicon steel sheets (grades Q11 and Q10) in its first-generation energy-saving transformers. This replaced outdated hot-rolled silicon steel sheets (such as D44), which had higher magnetic hysteresis loss.
- Energy-Saving Outcomes: Combined with targeted structural improvements, this material upgrade reduced the transformer’s no-load loss by 40%. CHH Power’s strict material quality control—including third-party testing for magnetic conductivity and hysteresis performance—ensures consistent low-loss operation across its product line.
For electromagnetic wires, CHH Power selects high-conductivity copper alloys to minimize load loss (energy dissipated during current transmission), further enhancing overall energy efficiency.
2. Design Optimization and Process Improvement: Maximizing Material Performance
CHH Power leverages advanced design tools and manufacturing processes to unlock the full potential of high-quality materials, making this a core research focus for its engineering team.
- Computer-Aided Design (CAD) for Optimal Material Ratio: CHH Power uses specialized CAD software to optimize the “copper-iron ratio”—the balance between electromagnetic wires (copper) and silicon steel sheets (iron). The design goal is to achieve the lowest total loss (sum of no-load and load loss) while minimizing material consumption. This digital optimization ensures that high-quality materials and structural design intersect at an optimal point, maximizing energy-saving effects without increasing costs unnecessarily.
- Core Seam Structure Innovation: A breakthrough improvement in CHH Power’s transformer design is the evolution of core seam structures:
- Traditional design: Used direct seams, which caused abrupt changes in magnetic permeability direction at core joints, increasing no-load loss.
- CHH Power’s upgraded designs: Adopted semi-straight seams, semi-oblique seams, and fully oblique seams. These structures smooth the magnetic permeability direction of Q10/Q11 grain-oriented silicon steel sheets at joint areas, reducing magnetic resistance and further cutting no-load loss.
This structural innovation, paired with precision manufacturing (e.g., laser cutting for seam alignment), has become a standard feature in CHH Power’s S11 and above energy-saving transformer series.
By combining premium materials with data-driven design and process upgrades, CHH Power’s transformers achieve industry-leading energy efficiency, helping clients reduce operational costs and carbon footprints.
