FAQ
Yes, absolutely. While copper is the traditional standard, modern SCB10 all-aluminum dry-type transformers are engineered to be 100% safe, reliable, and incredibly cost-effective:
1) Enlarged Conductor Cross-Section: Because aluminum has slightly lower conductivity than copper, the aluminum coils in our SCB10 series are specifically designed with a much larger cross-sectional area. This guarantees that they can carry the exact same electrical load as a copper winding without generating excess heat or sacrificing capacity.
2) Advanced Argon Arc Welding: The connections between the aluminum coils and the terminal blocks utilize highly advanced argon arc welding processes. This prevents the oxidation and loosening that plagued old aluminum wiring, ensuring a permanent, low-resistance connection.
3) The Economic & Weight Advantage: Aluminum is significantly lighter and far less susceptible to the wild price fluctuations of global copper markets. By choosing the all-aluminum SCB10, you secure a reliable, Tier 2 efficient transformer at a highly competitive capital cost, while also reducing the load-bearing requirements for your installation floors.
An aluminum dry type transformer uses aluminum winding instead of copper, without liquid oil for cooling. It relies on natural or forced air heat dissipation. It features lightweight structure, stable electrical performance and lower material cost. Widely used in indoor power distribution, commercial buildings and data centers. It has no risk of oil leakage and meets fire protection requirements for densely occupied areas.
Aluminum dry type transformers bring obvious benefits including light weight, anti-flammability and maintenance-free operation. No oil tank removes leakage and explosion hazards. Aluminum material cuts down overall product cost while keeping reliable insulation. They can be installed indoors close to loads, suitable for hospitals, schools and subway power supply systems.
Our aluminum dry type transformers serve many indoor power supply occasions. Common fields include shopping malls, office buildings, metro stations, data centers and industrial workshops. They are preferred for places with strict fire and environmental standards. Since there is no insulating oil, they can be mounted near load equipment to shorten power transmission distance.
The aluminum dry type transformer adopts air cooling design. Natural air cooling works under normal load, while forced air cooling supports short-time overload. Aluminum windings have good thermal conductivity. We optimize the winding structure and insulation layout to improve heat exchange. Regular dust cleaning is the main simple maintenance to keep stable heat dissipation.
