The application of the 400MVA/230kV power transformer can significantly improve the economy of the UHV substation, and matches well with the transmission capacity of UHV lines, which has wide prospect of application. Because of its large capacity and large volume, the whole transportation weight with nitrogen is about 470-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of 400MVA/230kV power transformer. In order to make the products applicable to any UHV substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity UHV Transformer” as a key scientific research projects, and entrusted BTW to carry out the research.

During the process of research and development, BTW adopted the advanced design technology and modular design, the transformer can be transported disassembly and with advantages of compact core and winding body, less transportation weight and low transportation cost, effectively solves the need of UHV construction in the transportation restricted areas. By using the most advanced 3D magnetic field calculation software, BTW performed detailed analysis and calculation for the magnetic flux leakage and eddy current loss of the transformer coil, iron core and oil tank steel structures. Besides, by using of the advanced electric field calculation software, BTW performed detailed analysis and calculation of main longitudinal insulation, and mastered the arrangement of the main longitudinal insulation of large capacity UHV transformer and the control of distribution of winding magnetic flux leakage. All of which make the products with low loss, low noise, small volume, strong anti short circuit ability, no local overheating and other significant advantages, and guarantee the long-term safe and stable operation.

The world's first on-site assembled large capacity UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of  the 400MVA/230kV power transformer, which marks BTW has fully occupied the world transformer industry technical peak. The successful development of the product filled the gaps in the domestic technology and met the urgent need of UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.

Q:A transformer step up 15V ac to 80V ac while its step down ratio is 30:1(240 to 8 V ac). how possible ?
Ok firstly,you're going to need ALOT more than 80v if you plan to power a transformer. When in its transport form, be it a plane, car, lorry etc you can run it on ordinary diesel fuel, however in Robot form, In order to make it walk, your transformer would need far more power than a diesel engine could provide. Take Optimus Prime for example, the weight ratio of Prime, which would likely exceed 75 to 80 lbs per inch might be impossible to provide enough power to move your transformer on two legs. If you are well educated in hydraulic engineering, hydraulic power might allow your transformer to walk, but the hydraulic system itself would create a different lot of problems.The hydraulic pipes, along with your transformers fuel lines and electrical wiring, would have to remain undamaged or even untouched during transformation, and a secondary power source must be used to power the hydraulic pumps. In conclusion, If you're planning to power 35 to 40 tons of pure machine, good luck. Hope this helped.
Q:Conservation of Energy in Transformers?
A transformer makes use of Faraday's law and the ferromagnetic properties of an iron core to efficiently raise or lower AC voltages. It of course cannot increase power so that if the voltage is raised, the current is proportionally lowered and vice versa. hyperphysics.phy-astr.gsu.edu/hba Goodbye

Q:Transformers Animated Series?
Transformers G1: On DVD Beast Wars: On DVD Transformers Armada: On DVD Transformers Energon: On DVD Transformers Cybertron: On DVD Transformers Animated: Season 1 is on DVD. I'm not sure if there were any other seasons made. Transformers Prime: Not on DVD I think this animated series is pretty new. There may be a DVD release in the future, not sure. I hope this helps!
Q:Transformers Toys Class Difference?
Yes the scale defines scale, size and complexity. Deluxe is usually around 10.00 and are the smallest and least intricate. Voyager is around 20.00 and are the middle class, and more advanced than Deluxe. Leaders are around 40.00 and are the most advanced. There is also Ultimate which go for 50.00 and up. There aren't any Ultimate out yet, but an Ultimate Bumblebee is coming out for around 90.00.

Q:The new iPad or the Transformer Pad Infinity ?
Transformer Pad Infinity. The new iPAD is exactally like the iPAD 2. Dont let them fool you with the X after the A5 on the processor. Technically its the same. The Transformer Pad Infinity is the first Quadcore tablet in the market with the targea 3 and quite frankly thats reason enough to bypass the New iPAD anyday.
Q:Is the transformer a power supply?
Here, are relatively speaking. 1, if your equipment behind the transformer, then the output of the transformer is your power. 2, if your equipment in front of the transformer (such as a substation or generator), then the transformer is your load. 3, for example: at home, the adapter (to the phone with a transformer device), it is for your phone, that is, power, you said the socket, it is the load. 4, but if it is necessary to define it as what equipment, then it does not belong to the power supply equipment (power supply with a large generator, a small dry battery). It is able to change the power supply mode of the device.
Q:Transformers or Go-Bots?
dude gobots sucked. they were a poor mans transfromer
Q:Why is the transformer coil insulation?
Because the transformer is used in different environments, according to different insulation level selection, can extend the life of the transformer. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
