Oil immersed Distribution Transformers 6-10kV

1. Introduction

6-10kV oil-immersed distributiontransformers with capacity 30-3150kVA are suitable for 6-10kV distributionnetwork system. Product complies with GB/T6451-2008 standards.

Type 9, 11 and 13 are classified byloss standard. Two types of oil tank are provided, they are sealed corrugatedradiating and sheet radiator. Voltage can be adjusted with load through switchinstalled.

2. Characteristics

Fully sealed corrugated tank has corrugatedsheet for transformer oil natural cooling. There is no oil storage cabinetneeded, so the oil is completely isolated from air. This design slows down theaging of oil, eliminates maintenance and extends the transformer life.

Q: I haven't seen Dark of the Moon, but I recently got OBSESSED with Transformers. Please don't spoil anything, but I'm curious, how do they incorporate the new chick, Rosie, Huntington-Whitely, in the movie? Do they ever explain where Micheala went(Btw- I KNOW what happened to Megan in real life.that's not what im asking lol) So yeah, thanks!Bq: SAY OPTIMUS PRIME IF YOUR A GIRL TRANSFORMER FAN:)Bq: Do MOST girls like Transformers, or is it mostly guys who like it?: OMG I freaking love transformers! I hate the new girl though!All they say about megan is that they broke up OPTIMUS PRIME

Q: Electrical Machinery, Electric Machines, 3-phase transformers: Advantages Of Transformers

Q: I need this Radio Shack transformer to provide power to a HO scale model train board lighting system. This transformer will be connected to a brightness control system and then the brightness control system will be connected to building lights and street lights. I have been told this issue is a safety and Electrical Code concern?: a acceptable web site. Face the construction south with residing house windows in basic terms in the south elevation. the north elevation could the two have a small variety of small residing house windows or be breamed with earth. For an present residing house, Geothermal is huge in case you have the money. the traditional forced warm air gadget that maximum US properties has is likely considered one of the main effective for the preliminary value and maintenance in comparison to the warmth is generates. A German business enterprise, called viessman (sp) creates very useful structures for this configuataion.

Q: I need to find a transformer that will convert 480 input to 240 output for a motor controller. Where can I get this type of transformer? I've only been able to find 120/240 transformers.Thanks.: Check with a supplier who sells industrial/commercial transformers and other electrical equipment. There should be one in your local yellow pages, or online. You will need to know what kVA rating is required for your motor as well.

Q: I am making a small Tesla Coil, but have a question regarding the transformer. Would it work to simply wind one myself with the correct winding ratio to get the voltage I want (around 7-10kv) or is it better to stick with a commercially available transformer? (I would rather not have to buy one) Any advice for winding a transformer?: I built a Jacob's ladder using a 15 kV neon sign transformer. I found a good used one for less than $50, and it sure beats winding the coils. Check OKorder and craigslist.

Q: Hi:I found a 10,000 WATTS STEP UP TRANSFORMER.Following are its characteristics: 1- 10,000 Watt Maximum Capacity Heavy-Duty Continuous Use Transformer. 2- Converts 110/120V upto 220/240 VoltsWhat will be its input?I means which battery or Generator i have to use for its input?Is it good idea to use that transformer to supply electricity to 1 house?: If you live in USA or Canada,electricity voltage is 115v. You may connect the two wire that mark with 120v into the house electric main power panel,use a 10 amperes breaker to protect your house power source if the transformer that you found is defective. The output shall produce 240v,it is good to run a stove or dryer,because they need 240v. Some country house does not have 240v source. If you live in other country that using 240v power source. You may use this tranformer to produce 120v to run some electronic device that buy from USA. Or you may join the 120v coil with the 240v coil in series to produce 360v .

Q: First of all, try not to be bias ;). My birthday is on December 19th, exactly the release date of the Transformer Prime, which is a great tablet, one I think surpasses even the iPad 2. With Steve Jobs gone and the new quad core installed in the Prime, would the iPad 3 be likely to be better than the Prime? Should I just wait for an iPad 3 if so? Thanks :)!: First of all, don't forget that the iPad 3 hasn't been announced and it will probably be a few months, at least, before it comes out. Secondly, there are sure to be spec improvements and additional features in the iPad 3. Whether they match up to the Transformer Prime, however, is anybody's guess. Third, I think the real decision should come down to if you want the Apple environment or the Google environment. Last I checked there are more iOS apps than Android apps, and if you have a Mac, iCloud is a nice thing to keep everything in sync across devices. I personally like iOS, its interface, and the way updates are delivered (as opposed to with an Android device, updates Google produces may not coincide with a new product release or may not be available right away for your device). On the other hand Android is more open, the integration with Google Calendar and all is great, there are less restrictions on what apps are allowed in the Android store, and if you are happy with Android then there's no real reason to wait for the iPad 3.

Q: I watch Terminator Salvation first, it was really good I thought. The best part of the movie, I thought, was when T-800 turns evil again and attacks John. It took both John and Kyle to beat T-800.But other than that, I didn't really enjoy Transformers 2. Neither did I make plans to watch it, and I thought they should've dropped Megatron as one of the villains again. I thought it was average.But which is the better sci-fi movie of the year? (I think Star Trek is, but that's out of the question.): Terminator Salvation

Q: even though the output voltage of a transformer can be much larger than the input voltage, the power output is nearly the same as the power input.Determine the relationship between the input and output current and the number of turns in the input and output coils.help!!!!!!!!thank you: If turns ratio is N, output turns divided by intput turns, then voltage ratio is also N, and current ratio is 1/N For example, a 120 VAC transformer with a 12 volt 10 amp secondary will have a turns ratio of 1/10, a voltage ration of 1/10 (12/120) and a current ratio of 10 (1 amp in primary, 10 amps in secondary) .

Q: actually I've many questions :) I've opened many mobile chargers and I didn't found the usual (bulky) transformer . I found only a small transformer and I think it called smps transformer.1- I can't understand how bulky transformers can be replaced by small ones! what is the idea ?2- are smps transformers connected directly to 220 volt like the bulky transformers ? if no, what is the design of the circuit that makes small transformers are able to be connected to 220 volt ?3- do smps transformers make a voltage drop like the bulky transformers ? or they have another job ?4- some smps transformers have 4 pins and the other have 5 or 6 pins, I know it should have 2 pins for input and 2 pins for output, why some of therm have more than 4 pins ?Thanks in advance, I hope i'm not bothering you because of my many questions :): The higher the switching frequency, the smaller you can make the transformer without the metal core saturating.
