High-Overload Transformer
Product description:
A high-overload-capacity transformer is one that possesses superior resilience against heavy loads, effectively preventing the unit from burning out due to overload conditions. Historically, to prevent transformers from becoming severely overloaded during peak electricity demand periods, power supply utilities typically implemented capacity-expansion measures—specifically, replacing existing distribution transformers with larger-capacity units—to accommodate these load surges. However, while such capacity-expansion retrofits successfully averted transformer burnout caused by short-duration, high-intensity overloads, they introduced new drawbacks: during off-peak periods, these oversized transformers operated at low load factors, failing to achieve their optimal economic operating efficiency while simultaneously driving up operation and maintenance costs. High-overload-capacity transformers, conversely, offer an effective solution to these challenges; they are capable of safely handling severe, short-duration overload conditions while maintaining a high load factor during normal operation, thereby reducing operation and maintenance expenses and demonstrating excellent economic efficiency.
Product features:
In addition to meeting normal temperature rise limits, the unit is capable of sustained operation—without compromising the transformer's normal service life—at 1.5 times its rated capacity for 6 hours, 1.75 times its rated capacity for 3 hours, and 2.0 times its rated capacity for 1 hour.
