110KV oil immersed power transformers strictly designed and produced with the IEC standard and most advanced technology have great reputation and the best sell performance all over the world. 110kv Power Transformer Description The oil immersed power transformer consists of core, coil, voltage regulator, oil tank, oil conservator, insulating oil and other protection and control components. The transformer is used for voltage stepping up or down and AC power transmission. The 110KV power transformer is also very important equipment for the electrical grid, power generator system, industrial and mining factory, etc. Besides, 110kv power transformer is essential equipment in the long-distance transmission of electric power, so transformer workplaces generally are some rural areas and even wastelands. These working conditions require transformers to be highly reliable. It just meets one of the most outstanding characteristics of our 110 KV transformer, in the meantime, with low loss and high efficiency, our oil filled transformer severs electrical transmission smoothly. 110KV Power Transformer Characteristics Good Mechanical Strength Through software simulation, the weakness of structural parts is eliminated for improving the mechanical strength of structural parts. Manufacture by high strength steel plate. Using laser cutting equipment for processing, the deformation and stress is small. High Earthquake Resistance The dynamic design method is adopted for the bushing. The horizontal acceleration is set as 0.5g, the waveform is set as the resonant sinusoidal third harmonic, and the loading position is the lower end of the casing flange seat. The main body of our 110KV power transformer adopts the static design method, and the static horizontal acceleration is 0.5g. Low Temperature Rise The reasonable structure of oil flow distribution is adopted to reduce the winding hot spot temperature rise and average temperature rise. The winding of large capacity transformer is provided with axial oil passage. 3) Control the transverse eddy current loss of the winding. High Resistance to Short Circuit Short circuit mechanical force is calculated by the dynamic analysis method. The self-viscous transposition conductor is used in low voltage, which effectively increases the short-circuit resistance. The machine body adopts constant pressure drying integrated type, and the integrated assembly adopts hot suit. As one of the leading manufacturers of transformers, we provide different types of transformer, contact us to know more.

Material Introduction MACOR® can be considered unique as its composition comprises 55% fluorophlogopite mica and 45% borosilicate glass. Corning’s unique production process results in Macor’s microstructure that is a key to its versatile properties. MACOR® offers a unique combination of properties, unlike any other technical material.It is a white, nonwetting, odorless and non outgassing material that exhibits zero porosity.Extremely machinable, MACOR® offers tight tolerances capabilities,allowing complicated shape design (optimal performances up to +/- 0.013 mm for dimensions, < 0.5 μm for finished surface and up to 0.013 μm for polished surface). MACOR® remains continuously stable at 800 °C, with a maximum peak at 1000 °C under no load, and unlike ductile materials, doesn’t creep or deform. Its coefficient of thermal expansion readily matches most metals and sealing glasses. As an electric insulator, particularly at high temperatures, it is excellent at high voltages and a broad spectrum of frequencies.
