10KV Oil-Immersed Transformer
S11-M series 10KV low-loss fully sealed power transformers implement national standard GB1094 "Power Transformer" and GB/T6451 "Three-phase oil-immersed power transformer technical parameters and requirements".
The fully sealed power transformer eliminates the oil conservator, and uses the fin plate of the corrugated oil tank body as the heat dissipation cooling element, and expands and contracts with the increase and decrease of the transformer oil, so that the inside of the transformer is isolated from the atmosphere to prevent oil deterioration and insulation moisture and aging. , enhances the reliability of operation. The core adopts high-quality cold-rolled silicon steel sheet, which effectively improves the distribution of magnetic flux density inside the core, reduces noise and reduces loss. The coil is made of high-strength enameled wire (or paper-wrapped wire), cylindrical (or cake-type) structure, uniform distribution of ampoule, reasonable insulation structure and strong resistance to short circuit. The fasteners used in the fuel tank are all made of anti-return nuts, which can ensure that they will not be loosened after long-distance transportation. The surface of the fuel tank is phosphatized and coated with three anti-paints (moisture proof, mildew proof, anti-salt mist), which are widely used in metallurgy, mining, petrochemical and other environments where the use environment is harsh.
The S11-M series ring-type iron core distribution transformer is characterized in that the iron core of the ring-type iron core transformer is made of special equipment, and the silicon steel sheet is wound into a three-phase three-core column, the iron core has no gap, no joint, and the transformer coil is adopted. The patented equipment is wound on a closed core, and the whole transformer achieves the purpose of energy saving, consumption reduction and environmental protection. S11-M series ring core distribution transformer is especially suitable for agricultural network load characteristics. It can be used as one of the preferred models for urban and rural power grid construction and renovation projects and other power distribution projects.

Note: Transformers used under special conditions must be stated when the product is ordered
1. The no-load loss is 20-35% lower than S9, and the energy saving effect is remarkable;
2. The no-load current is 70-85% lower than S9, which improves the power supply quality of the grid and reduces the line loss;
3, the noise level is reduced, 30-45DB, effectively eliminating noise pollution;
4. S11-M series 10KV low loss fully sealed power transformer has super overload capability;
5. Because the iron core structure is reasonable, the loss is small, and the current is small, so the temperature rise of the transformer is very low.
