Features | |
Structural features | The oil-immersed distribution transformer produced by our company adopts a new insulation structure to improve the short-circuit resistance; the iron core is made of high-quality cold-rolled silicon steel sheet; the high-voltage windings are made of high-quality oxygen-free copper wire, and Adopt multi-layer cylindrical structure; all solid parts are treated with special anti-loosening treatment. |
Technical Features | The product has the characteristics of high efficiency and low loss, which can save a lot of power consumption and operating costs, and has significant social benefits. It is a popular new technology product. |
reliable structure | |
structural improvement | 1. Spiral coil with longitudinal oil channel, better internal heat dissipation; |
2. The effective support of the coil end face is improved, and the ability to resist short-circuit current is stronger; | |
3. A new hoisting structure and body positioning structure are adopted to ensure more reliability in long-distance transportation and operation; | |
4. We also have many unique and reliable structures to serve you; | |
5. Selecting a transformer with a higher performance level will have a higher level of technical content. | |
high quality material | |
Oxygen-free copper wire | Oxygen-free copper wire with lower resistivity is selected, and after a series of additional surface treatments, it is smoother and has no burr sharp corners, so that the load loss of the transformer is lower and the electrical performance is more reliable. |
High quality silicon steel sheet | High-quality silicon steel sheets are selected, and with the improvement of performance level, silicon steel sheets with lower unit loss are used, so that the no-load loss of the transformer is lower. |
Premium quality laminated wood insulation | Choose high-quality laminated wood insulation, never crack, even under the action of short-circuit current, it will not move. |
Deep filtered transformer oil | Using deep-filtered transformer oil with lower water, gas and impurity levels, the transformer works more reliably. |
High quality rubber sealing material | Use high-quality rubber sealing materials to effectively prevent aging and prevent leakage. |
Raw materials are inspected | There are quality inspections of raw materials, and all raw material manufacturers have undergone strict inspections in accordance with the national standard ISO9000. |
Good technical and economic performance | |
Performance | On the basis of the S9 series, the S11 series products have an average no-load loss reduction of 30%; no-load current is reduced by 70-85% compared with S9; It can still operate for a long time under the conditions of high temperature; the operating noise of the product is reduced by 2-4 decibels on average. |
fully sealed | |
Improved sealing structure | The oil tank adopts a fully-sealed structure. Compared with the ordinary oil-immersed transformer, the fully-sealed distribution transformer cancels the oil conservator. The wave fin of the oil tank replaces the oil pipe as the cooling and heat dissipation element. The corrugated oil tank is made of high-quality cold-rolled sheet on a special production line. , The wave fin can expand and shrink the volume of transformer oil, so as to isolate the transformer from the atmosphere, prevent and slow down the oil deterioration and insulation moisture, enhance the operational reliability, and maintain normal operation without maintenance. The surface of the corrugated fuel tank is coated with conformal paint after degreasing, rust removal and phosphating treatment, which is suitable for use in metallurgy, petrochemical, mining and other environments. |
