S13‑M‑160KVA 10/0.4kV three‑phase hermetically‑sealed oil‑immersed distribution transformer adopts oxygen‑free copper winding and high‑permeability CRGO silicon‑steel core. It applies ONAN oil natural cooling, with mineral oil working as both insulation medium and heat dissipator. Vector group Dyn11, rated frequency 50Hz, short‑circuit impedance 4%, no‑load loss around 240W, load loss around 2100W, total weight approx. 860 kg. The corrugated fully‑sealed tank prevents moisture and dust ingress, cuts maintenance work and extends service lifespan.
This unit suits pole‑mount outdoor installation or installation inside compact substation boxes. It is widely deployed for urban‑rural grid upgrading, small‑and‑medium factories, commercial buildings, residential districts, PV supporting projects and temporary construction power supply. Capable of continuous stable operation within ambient temperature ‑25℃~+45℃. Compliant with GB and IEC60076 standards, 100% factory routine‑tested. Tap range ±2×2.5% for voltage adjustment. Packed in wooden case for sea or land transportation, it serves as cost‑effective mainstream medium‑capacity distribution equipment.
