Oil Immersed Distribusion Transformer
S11-M Series Three-phase Double-winding 20kv Distribution Transformers With Off-circuit Tap Changer
It adopts advanced electromagnetic design software, and meets IEC60076, GB1094, GB/T6451, GB/T25289-2010 standards.
Without such device like conservator, air breather… . So it ensures that the transformer oil is not in contact with air, improving the anti-oxidation capacity of the transformer oil and delaying its aging. The core is made of high quality cold-rolled grain-oriented silicon steel sheet, with laminated structure miter joint, so as to reduce the no-load losses and no-load current. The tank is a corrugated type, the corrugated fins can swell and shrink with the change of transformer oil, so that the pressure can be maintained inside the tank, increase its reliability and anti-corrosion capability The coil of distribution transformer, wound by high intensity enameled wrapped conductors with good Ampere-Turn balance and reasonable insulation structure, has a strong short-circuit withstand capacity. The distribution transformer adopts the-free-untanking structure with sealing material parts made of high quality acrylic rubber, it can effectively prevent against light-aging and heat-aging.
