This 110KVA dry‑type transformer works at 10kV/0.4kV with Dyn11 connection, F‑class insulation and 4% short‑circuit impedance. Typical no‑load loss reaches 230W, 75℃ load loss around 1750W, sound level ≤50dB(A) at 1‑meter distance, partial discharge ≤10pC. Manufactured per GB1094.11, GB/T10228 and IEC60076 standards, it holds CCC, CE and ISO9001 certifications. Built with pure‑copper windings and low‑loss silicon‑steel core via vacuum epoxy casting, it is oil‑free and fire‑safe with no fire‑barrier civil works required. It is widely installed in poorly‑ventilated indoor spots including basement substations, hospital technical floors and campus main‑building power rooms, supplying mixed loads of elevators, central air‑conditioning, lab test instruments and public lighting. Equipped with smart temperature controller offering over‑temperature alarm, trip function and RS485 port for building power monitoring. AN natural air cooling supports continuous full‑load operation; AF forced air cooling enables 140% short‑time overload capacity. Unit weight approx 820kg, shipped in solid wooden crate. IP20 enclosure is optional for touch‑protection. Numerous field references are available for domestic commercial‑industrial retrofits and overseas small‑medium building projects.
