S13M oil-immersed three-phase distribution transformer
product features:
The three-phase oil-immersed distribution transformer produced by our company adopts a new type of insulation structure to improve the short-circuit resistance. The iron core is made of high-quality cold-rolled silicon steel sheet. High-voltage windings are made of high-quality oxygen-free copper wires. All fasteners adopt special anti-loosening treatment.
products have the characteristics of high efficiency and low loss, can save a lot of power consumption operating costs, social benefits are significant, is a high-tech products.
and reliable structure:
our company has made many improvements on the basis of traditional structure and mature technology, such as adopting:
The effective support of the coil end face is improved, and the short-circuit current resistance is stronger;
The new hoisting structure and body positioning structure are adopted to ensure more reliable in long-distance transportation and operation;
◆ We also have many unique and reliable structures to serve you;
◆ Selecting transformers with higher performance level will have higher technical content.
high-quality materials:
choose oxygen-free copper wire with lower resistivity and undergo a series of additional surface treatments, which are smoother and have no burrs and sharp corners, thus making the load loss of the transformer lower and the electrical performance more reliable.
, high-quality silicon wafers are selected. With the improvement of performance level, silicon steel sheets with lower unit loss are adopted to make transformer no-load loss lower.
, high-quality laminated wood insulation is selected, which will never crack and will not move even under the action of short-circuit current.
, transformer oil with deep filtration is selected, with lower water content, gas content and impurity content, and transformer operation is more reliable.
uses high-quality rubber sealing materials to effectively prevent aging and prevent leakage.
the quality inspection of all raw materials, all raw material manufacturers have undergone strict examination ISO9000 in accordance with national standards.
has good technical and economic performance:
S11 series products reduce no-load loss, load loss and no-load current by 10%, 24% and 46% respectively compared with S9 series, thus reducing the operating cost by 19%.
S13 series products are based on S11 series, the no-load loss is reduced by 30% on average. The no-load current is 70-85% lower than S9. The average temperature rise is reduced by 10K, which improves the service life. It can still operate for a long time even under the condition of 20% overload; the operating noise of the product is reduced by 2-4 decibels on average.
fully sealed (m):
M in S11(M) and S13(M) is selected to indicate that the oil tank adopts a fully sealed structure. Compared with ordinary oil-immersed transformers, the fully sealed distribution transformer eliminates the oil storage tank. The wave fin of the oil tank replaces the oil pipe as the cooling and heat dissipation element. The corrugated oil tank is manufactured by high-quality cold-rolled sheet on a special production line. The wave fin can expand and shrink with the expansion and contraction of the transformer volume, thus isolating the transformer from the atmosphere, prevent and slow down oil inferiority and insulation moisture. Enhance operational reliability and maintain-free normal operation.
Three-proof paint coating after oil removal, embroidery removal and phosphating treatment on the surface of corrugated oil tank is suitable for use in metallurgical, petrochemical, mining and other environments.

Features:
- Low noise: compact design structure, application of new materials and new processes, noise reduction, no oil storage cabinet, lower height than similar products. No oil change is required during the normal life period, which improves the safety and reliability of power grid operation.
2. When the transformer is packaged, the vacuum oil injection process is adopted to completely remove moisture from the transformer oil tank. After sealing, the transformer is not in contact with air, which effectively prevents oxygen and moisture from entering the transformer and causing the insulation performance to decrease (insulation material and oil aging), so it is not necessary to conduct regular oil sample tests.
3. Reliable long-term service life: The fully sealed transformer box cover and box edge are bolted or welded to isolate the contact between oil and air, and the insulation will not be affected with moisture, which greatly reduces the insulation aging speed and improves the service life.
4. Small size and beautiful appearance: S11-M series transformer oil tank adopts corrugated plate heat sink. When the oil temperature changes, the change of oil volume is adjusted and compensated by the elastic expansion and contraction of corrugated plate. The corrugated fuel tank is beautiful in appearance, small in size and small in footprint.
5. No hanging core: Users do not need to check the hanging core before the fully sealed transformer runs, and users can save the cost of hanging core inspection. Maintenance-free: fully sealed transformer does not need maintenance.
