Produced by Jiangsu Yuantong Electric, this 200KVA 10KV three‑phase dry‑type transformer is SCB13 series with 10kV/0.4kV ratio, Dyn11 vector group and 50Hz rated frequency. ±5% off‑circuit tap‑changing is available on high‑voltage side. It uses pure copper windings with H‑class epoxy vacuum casting insulation for low partial discharge, good moisture and dust resistance, free of oil leakage and fire risks. Weighing about 750 kg, it adopts cold‑rolled silicon steel core for low loss and strong short‑circuit resistance. Equipped with intelligent temperature control, it can be fitted with IP20 enclosure, widely used in workshops, commercial buildings and small new‑energy projects. Packed in wooden case, lead time is 20‑30 days. Full tests including withstand voltage and partial discharge are completed before delivery, and customization is supported.
