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 1250kVA 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.
