Oil Immersed Transformer Series

Overview
Amorphous alloy transformer is a low-loss, high-efficiency power transformer. This type of transformer uses iron-based amorphous  metal as the core. Since this material does not have a long-range ordered structure, its magnetization and demagnetization are easier than general magnetic materials. Therefore, the iron loss (i.e. no-load loss) of amorphous alloy transformers is 70-80% lower than that of traditional transformers that generally use silicon steel as the core. As the loss is reduced, the demand for power generation also decreases, and greenhouse gas emissions such as carbon dioxide are also reduced accordingly. Based on energy supply and environmental protection factors, amorphous alloy transformers are widely used in large-scale development countries such as China and India. Based on the current electricity consumption in China and India, if amorphous alloy transformers are fully adopted in the distribution network, it can save about 25-30TWh of electricity and reduce 20-30 million tons of carbon dioxide emissions each year.

Overview
S11-M-ZT on-load capacity-adjusting transformer is a new product independently developed by our company. This product is a new technology energy-saving distribution transformer with two rated capacities of large and small and two rated The fixed capacity operation mode can automatically change the cap, which solves 10kV The seasonal load variation of the distribution network is relatively large, which causes large transformer losses. This overcomes the problem of no-load capacity adjustment transformer disconnection. The use of S11-M-ZT type on-load capacity adjustment transformer reduces the equipment purchase and installation costs compared to two S11 type transformers, and reduces the space occupied, and the construction and operation and maintenance workload is significantly reduced. At the same time, compared with the S11 type ordinary transformer, the no-load loss of the  S11-M-ZT type on-load capacity adjustment transformer is reduced by 50%. In addition to being applicable to rural power grids with large seasonal load variations, it is also applicable to some urban commercial areas, development zones, industrial areas, radio stations, oil fields, etc., where day and night load variations are significant.

Product Overview
S13-M. RL, S11-M. RLThe three-dimensional wound core power transformer is a revolutionary product after the laminated wound core power transformer. It is a more reasonable structure and high performance. A new type of energy-saving transformer with better performance and more significant energy saving. With the second urban and rural power grid construction and transformation and various power projects being launched one after another, how to improve the technical content of power transformers, better implement the national energy conservation and consumption reduction and environmental protection policies, and actively promote new energy-saving, low-consumption, environmentally friendly and applicable products has become an important issue before us. The three-dimensional wound core power transformer produced by our company is a kind of traditional material, but with lower operating noise, better loss reduction and material saving, which is fully in line with the international and domestic low-carbon economy and energy conservation and emission reduction policies. This product has been included in the first batch of energy-saving products selected by the national energy-efficient power plant, and the investment project of the central budget for national resource conservation and environmental protection. The State Economic and Trade Commission and the former State Power Corporation  have successively issued documents to promote this energy-saving product. Shenyang Transformation Institute has also promoted the three-dimensional wound core as a replacement product for laminated and flat wound core power transformers.

Overview
With the continuous development of my country 's economic construction, the improvement of people 's living standards, the increase in electricity load and the increase in transformer equipment have led to large energy consumption and increased noise, seriously polluting the urban environment. For this reason, countries around the world are calling for and taking steps to  reduce energy consumption and improve the  urban environment. S13-MThe series three-phase distribution transformer is moreS9, S11Compared with the type, The no-load loss is reduced by 50% and 30% respectively, and the noise level is reduced by 5-8%.db.

High-quality materials
◇ Use oxygen-free copper wire with lower resistivity, and after a series of additional surface treatments, it is smoother and has no burrs or sharp corners, which reduces the load loss of the transformer and makes the electrical performance more reliable.
◇ Select high-quality silicon steel sheets. As the performance level improves, silicon steel sheets with lower unit loss are used to reduce the no-load loss of the transformer.
◇ Made of high-quality laminated wood insulation, it will never crack and will not move even under short-circuit current.
◇ Use deep-filtered transformer oil with lower water, gas and impurity levels, making the transformer work more reliable.
◇ Use high-quality rubber sealing materials to effectively prevent aging and prevent leakage.
◇ All raw materials have been quality inspected, and all raw material manufacturers have passed national standards IS09000strict scrutiny.
