FAQ
Yes, absolutely. While copper has traditionally been standard, modern SCB18 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 SCB18 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.
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 less susceptible to the wild price fluctuations of global copper markets. By choosing the all-aluminum SCB18, you secure an ultra-high efficiency (Tier 1) transformer at a highly competitive capital cost, while also reducing the load-bearing requirements for your installation floors.
