Manufactured by Jiangsu Yuantong Electric, this 200KVA 20KV three‑phase dry‑type transformer adopts copper windings with epoxy resin vacuum casting, weighing around 1050kg. Its oil‑free design avoids leakage and fire risks, and the cast coils resist moisture and dust. It fits indoor locations with strict fire‑safety rules, such as power rooms for small‑and‑medium factories, indoor distributed photovoltaic stations and underground park substations where oil‑storage facilities cannot be installed. Intelligent temperature controller and forced air cooling are optional accessories. Standard lead time is 20‑30 days. Packed in solid wooden crates, it can be put into service after simple on‑site commissioning with low maintenance demand.
