Tanaka Electric
Our technology-oriented enterprise specializes in the R&D, production, and service of high-quality power distribution transformers. The 33kV series three-phase oil-filled distribution transformers are energy-saving solutions, available in S9, S11, and S13 series (with off-load tap changer OCTC) and SZ9, SZ11, and SZ13 series (with on-load tap changer OLTC).
1. Oxygen-free copper wire: Lower resistivity and smoother surface treatment for reduced load loss.
2. Silicon steel sheets: High-grade sheets with lower unit loss to minimize no-load loss.
3. Wood insulation: High-quality laminated wood components that resist cracking under short-circuit stress.
4. Filtered Oil: Deep-filtered transformer oil with minimal impurities for reliable operation.
5. Sealing: High-quality rubber materials to prevent aging and eliminate leakage.
