Product Description
Product Overview:
The new energy‑efficient, energy‑saving transformer utilizes high‑grade grain‑oriented silicon steel for the core and oxygen‑free copper with excellent electrical conductivity for the windings. It reduces no‑load losses by more than 30% and load losses by over 20%, resulting in an overall loss reduction of approximately 25%. During grid operation, this design maximizes the economic benefits of energy‑saving transformers.
Product Features:
1. Reduce no-load losses.
Employing high-performance silicon steel laminations with a five‑step lap joint, the core structure and manufacturing process have been optimized to reduce the process factor. The upper yoke laminations are left uncoated, and shear burrs are kept below 0.02 mm.
2. Reduce load losses.
Wires are drawn from oxygen-free copper rods, which have higher electrical conductivity than electrolytic copper, thereby enhancing the conductor’s conductivity. By appropriately reducing the current density, optimizing the insulation structure—employing semi-oil channels, pre‑formed insulation components, integral winding assembly, self‑adhesive wire, and self‑adhesive paper—we can minimize the insulation volume, increase the winding fill factor, and reduce the winding dimensions, thus lowering load losses.
3. Reduce wear and tear on other components.
Improving the core structure: Refine the design by controlling winding leakage flux and optimizing ampere‑turn balance, thereby reducing stray losses in structural components such as the oil tank. Employ corrugated oil tanks and plate‑type radiators to enhance heat dissipation efficiency.
