Basic Info

High Efficiency 33kV Oil Immersed Distribution Transformer is specially designed for medium-voltage distribution networks in Kenya and East Africa. It strictly complies with IEC 60076, KPLC and NEMA standards, adopting ONAN natural oil cooling and tropicalized insulation to adapt to high ambient temperature, heavy cyclic load and frequent lightning surge environments. It applies high-permeability grain-oriented silicon steel core and high-density aluminum winding, with hermetically sealed corrugated tank structure to slow oil aging and cut maintenance work. Reinforced interlayer winding insulation delivers strong lightning impulse withstand and short-circuit resistance, ideal for rural power grids and industrial power distribution projects across East Africa.
