The 30KVA 10KV three‑phase oil‑immersed transformer is a fully‑sealed small‑size distribution unit. It adopts copper winding with Dyn11 connection group and ONAN oil natural cooling, weighing about 280kg. It delivers low loss with favorable procurement cost. This model is widely adopted for scattered rural power areas, field communication base stations, small sand‑stone processing sites and off‑grid miniature photovoltaic projects. It can maintain stable power supply under open‑air weather exposure. Normal production lead time is 20‑30 days.
