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: I know my user name indicates that I looooove X-Men but I loooove Transformers too. I was wondering if anyone knew who the transformer that comes out of the pool is. I have looked at the concept art and can't figure it out.
- Im not sure but he is all silver so I think its Megatron.
- Q: Halo4 - love the series, Halo 3 is my favorite, hated Reach. not sure if Halo 4 is more like halo3 or more like reach, will not buy if abilities are includedBlack Ops 2 - BLOPS was my favorite shooter, I will probably get this unless they lower the health to MW2/MW3 standards and they don't fix SMGsTransformers FOC - War for Cybertron was one of the best games I've ever played, but they made Dark of the Moon which was a really bad shooter, and I'm not sure if FOC will be bad as wellWhat would you suggest?
- I would say BLOPS 2 because I have not played any of the other games prequels. That is because I play on ps3 so I am unable to play Halo and Transformers never interested me. Plus I know if there is an error in BLOPS 2 Treyarch will fix it to the best of their abilities unlike IW's take on development which is we have your money already so we don't care.
- Q: The specification states that the 35KV substation is capable of obtaining the power supply after the main transformer is powered down. Therefore, in this case, the transformer used should be connected to the power supply side of the circuit breaker. My question is that the main transformer which, the main transformer is not connected to the power supply side of the circuit breaker?
- Selection of main transformers Main transformer is mainly used for electrical system power supply, the general capacity of large, to ensure the reliability of electrical system power supply, improve the system impact resistance. 1, the number of the main transformer: In order to ensure the reliability of power supply, substation should be installed in general two main transformer. 2, the main transformer winding connection: 110KV using a direct grounding neutral point effective grounding system, using star wiring. If necessary, the use of triangular wiring by arc-suppression coil connected to the use of high-pressure side of the change. 35KV using arc suppression coil neutral point non-effective grounding system grounding point, the use of star wiring. 10KV generally use unattached system 3, the choice of the main transformer winding: China 110KV and above voltage transformer winding are used star wiring, 35KV also uses star wiring, 35KV following voltage transformer windings are triangular connection. 4, the choice of main transformer capacity: the main transformer capacity is generally based on substation built 5 to 10 years of planning load selection and take into account the late 10 to 20 years of load development, when a transformer outage, the remaining transformer capacity should Can guarantee 70% of the total load. The choice of choice Used to change the main power supply system, the capacity according to their own distribution load to choose. The number of units used to consider the general standby power supply, when there are two used when the variable, the use of single bus segment wiring, usually run to limit the scope of failure to improve the reliability of power supply. The power system uses 380 / 220V neutral point directly grounded three-phase four-wire system, power and lighting combined with a power supply.
- Q: Here's photos of the transformer in question. My dad pulled it put of some electronic he can't remember what and has had it sitting on the garage. Recently I've been working with high voltage and he pulled this out for me to work with just having trouble figuring it out
- First of all, never assume anything! There are some standard colour codes for transformer wiring, but not all transformers conform to the standards. In practice, a manufacturer can use any colour wire for any purpose, leaving you and me and a lot of other people wondering for all time, which wire is which? The measured DC resistance does not tell you anything about the AC voltage rating of any winding. With most power transformers, if there are two solid-black wires, they are the primary. If it is tapped, or there are two primaries (such as in dual-voltage units), there will be three or more primary wires (and possibly as many as 8!). I think the side with 115V on it is probably -- mind you, this is not for certain -- nothing more than the side on which that number happened to be stamped. So of course you want to know what to do next. Considering the number of wires and the ways in which they are connected, it would seem that an experimental method will be required. The 2006 ARRL Amateur Radio Handbook (and possibly other editions) tells how to figure out what's what with transformers. I strongly recommend using the procedures described therein.
- Q: I heard that a transformer is like a ratio device for amps and volts, but I know there must be more to it. How exactly does it work, and what happens when it doesn't have enough current, but enough voltage?
- There okorder
- Q: I know there has been plenty of Transformers anime over the years, but is there any Transformers manga?
- Have you tried googling it? Good luck! I remember seeing Transformers in JPN since I was little I think they've been around since the 80s. At least I've seen the toys in JPN since then.
- Q: can u use a 220v to 12v transformer step down transf, switch the primary as the secondary, and vice and make it a 12v to 220v transformer.
- confident. you will incur larger losses than if the transformer became particularly designed for 220 V, inspite of the undeniable fact that it is going to in all possibility be insignificant. be conscious, inspite of the undeniable fact that, that attempting the different (making use of a transformer designed for 220 V in a 440 V circuit) might _not_ paintings, because of the fact the conventional might overheat.
- Q: i need a transformers costume that can transform into a car, truck, etc i need to buy it for this kid for his birthday. medium size please. and he wants it as optimus prime.he wants it to look good and if he doesn't like it, well hes gonna be sad
- wrap urself in tin-foil. lol
- Q: Do you know what that show is called where there are these dinasaurs, and there are good oens, and bad ones, very similar to transformers.The dinasaurs transform into robots. Whats it called?
- it has to be a version of transformers lol
- Q: explain the role of both types of transformers in getting electric energy from an electric power plant (coal-fired, natural gas or nuclear) to our homes.
- The voltage is transformed up to thousands of volts and low current for minimum heat loss in the wires. Then down to low voltage at high current to the neighbor hood.
