Performance characteristics
1.A multilayer cylinder structure is used for all high voltage windings in order to improve the voltage impulse distribution of windings.
2.For the capacity range of low voltage windings is from 30kVA to 2000kVA,the cylinder type or spiral structure is used to ensure the high mechanical strength,ampere lure distribution,and excellent short-circuits proof performance.
3.The securing structure is set in the transformer body,which is used for ensuring that no displacement will occur during the transportation;meanwhile,the turnbuckles are mounted in fasteners,which is for assuring that fasteners will not be loose during the long term operation.
4.Corrugated tanks are used in transformer for replacing the conservator.The tank enclosure and rim are completety sealed by welding or bolting up,which prolongs the service life of transformer oil.
5.The transformer surface are painted with primer and finish coats after derusting,and phosphorizing;which can meet the special operation requirements in metallurgic and petrochemical industries,as well as,in moist and dirty places.
6.The press relief valves,signal thermometers,and gas relays are equipped in the oil tank of hermetically sealed transformer in order to the standard requirements for safe operation.The transformers are attractive and competitive due to the compact shape,excellent design,and maintenance-free.

- Q:Can you put dolar energy through a step-up transformer to create more energy?
- This question is worth people's attention
- Q:1. 6volts going in a 12:220v transformeris the output 220v or less, formulas, computations 2. 12v going in 12:220v transformer (1 amp 220VA)core loss, copper loss, eddy current loss etc etc3. 24v going in a 12:220v transformer. is the 220v, lost of power in the input,
- #1 - 107.8, assuming 6.0V into a 12.0V:220V transformer, with 98% efficiency. You can find the efficiency of the transformer, by looking at it's specifications. Most range from 98 to 99%. All this depends on the load as well, as a lightly loaded transformer has less loss that a fully loaded one. #2 - 215.6V. In order to get 1A@220V, you will need to supply #3 - 431.2V. 100% over spec, and bound to fail. I do not understand what you mean by is the 220V, lost of power in the inupt,
- Q:hi , i got some electronics frm asia( like camera and hair dryer) , which can only be used in 220 volts. which converter or transformer sud i use which changes 110 volt to 220 volt ? and where can i get it ? i searched for it . but i found converters that change 220 v to 110 volt :(
- Check Hammond, they have auto transformers that can be wired either step down or step up. You need to know the total wattage of the devices you have , and choose the largest one. Frequency, hopefully, is not an issue here.
- Q:Why the new operation of the transformer to be charged
- Transformer to charge? Can I charge it? You should make a mistake
- Q:I feel that Transformers was because that sh*t was hot! And Shia LaBeouf was pretty HOTT too!

- Q:Calling all fans of Transformers! I am looking for anyone to tell me if Transformers Animated is coming back for a third season on Cartoon Network. The reason why I am asking this question is because I recently bought the second season of the show and noticed that they have a lot of information on new characters as a special feature and I am wondering if those characters will be in the third season of the show.
- That would suck sooooo bad if it is cancelled. All that build up in the first season with super villains and no Megatron and like, 3 Decepticons till the end of season 2 for what! To take it all away just as its getting good and finally setting up a full on Autobot Decepticon war There better be a season 4 or this series will go in the forgotten bin with Robots in Disguise as another series that took forever to set just for 1 big battle then that's the end. But if it is the end then that will teach the writers for holding out on what fans really want. I can not sit through season 1 or 2 again, except the season 2 finale.
- Q:I want to step down a 240Vpeak signal to 24. Anyone know where I can get a transformer to do this? Also does frequency have a dependence on a transformer? The signal I am looking at has around 55Khz frequency. Thanks for your help
- You won't be able to find a transformer for that frequency, unless you are lucky. You will have to wind your own. Probably a ferrite core is best, depending on your power level, which you did not mention, and is an important design factor. If this is a very low power signal (you do use the word signal), perhaps a capacitive or resistive voltage divider will be enough. Or search for an audio signal transformer. .
- Q:I don't know how this conversation started today, but a couple of my friends asked me who would win in a battle Voltron or the Transformers. They did not specify which version of Voltron or which group of transformers. Give me a scenario and tell me what you think!
- i would have to pick the transformers only because in either group there are more than one of them as to where Voltron is all alone and probably wouldn't hold up to much against a bunch of transformers.
- Q:i have the 240V AC to 12V AC step down transformerwhen i connecting directly to 240V line the output is higher at about 16Vi need only 12V for my circuithow to get the exact amount of output voltage?
- You could get a second transformer with 120 VAC to 4 VAC output. If you connect the low voltage terminals in series and out of phase from one another (in a subtractive configuration), you will subtract the 4 V ac of one transformer from the 16 V ac of the other transformer, and reduce the combined voltage to 12 Vac. Alternatively, you can use a variac, which is similar to a variable, unity ratio transformer coupled to the 120 VAC side of the transformer. This will allow you to adjust the input voltage, thereby varying the output. Variacs are relatively expensive however. First, check the requirements of the load to make certain that 16 V ac is definitely too high. Some devices have a fairly wide range of tolerance.
- Q:Here we go I have 4 transformers (230V to 12V) and 4 radio receivers. I have one transformer connected to one receiver. Similarly all transformers are connected in the same way. Now, I used a connection box (normal heavy duty ones bought at hardware shop-i think its made of some kinda fibre) to house 2 transformers and 2 receivers. This scenario is happening in my roof. I went to open one of the box the other and the transformer was hot. It wasn't hot to the point of not being able to hold it. But hot enough for me to hold it for for a while before letting go. So the basics here is that one transformer is only powering one receiver which is OK for the load. But I am a bit worried as to whether this can start a fire in the roof. Any advice please? Can this scenario lead to a fire? (Even though there is no overloading)
- It's possible but very unlikely. Many transformers have a heat-operated fuse connected in series so that it breaks before the transformer coils get dangerously hot. It will be hotter inside because the heat can't escape easily, so if the transformer fails the wire will melt inside it, not on the outside. If you are worried about it then you could either check if your transformers have such a fuse, or if they don't, you could fit one yourself. You could also fit the transformers into a big metal box with air vents and a fan to help keep things cool. It's normal for a transformer to get warm, just feel any mains adapter in use. The main component is a transformer. Electrical fires are caused mostly by bad connections sparking, or bad practice which allows a cable to get red-hot from an overload, something which will not happen in a standard installation, because fuses and breakers are installed to prevent it. There is a huge difference between the temperature your hand finds uncomfortable, and the temperature of melting copper which could cause a fire.
