Product Description:

Production introduction

The dry-type transformers are casted with epoxyresin,which are made of high quality materials by means of a strict process with advanced production and testing devices.The product features high reliability and long service life.In accordance with different operation environment,it can be equipped with different protection casings or without casing.It can replace the oil-immersed transformer and be used in the high buildings,business centers,airports,tunnels,chemical plants,nuclear power stations and watercrafts ect.

Normal service conditions
1)Altitude should not be over 1000m:indoor type
2)Highest ambient temperature should not over:+40oC;Highest daily average should not over temperature:+30oC
3)Highest annual average temperature should not over +20oC,lowest temperature should not below -5oC.We can provide transformer operated in special conditions according to user's requirement.

Model designation

Applicable standards

Performance characteristics

1.The product is safe,fire-proof,pollution free,and can be used in the load center directly.
2.High mechanical strength,strong shour-circuit proof capacity,small partial discharge,excellent thermal stability,high reliability,and long service life.
3.Low loss,low noise,energy saving and maintenance free.
4.Excellent heat dissipation,great overload capacity and a large operating capacity is available when ONAF is applied.
5.Good humidity resistance,it's suitable for operating in the highly humid and harsh environment.
6.An intelligent signal and temperature control system is adopted,which can automatically monitor and display all working temperature of the three-phase windings.The blowing fan can give an alarm,switch on and off automatically and conduct tripping operation to protect the transformer.
7.Dur to the structure is compact and weight is light,it can save space and decrease the cost of installation.

Q:What kind of transformer is required to convert a 110 v microscope with a 6v, 10w bulb to a 220 v instrument?
What do you accomplish by converting a 110v appliance to a 220v appliance.
Q:220V to 12V transformer L N + V + V on behalf of what? The more detailed the better! Thank you prawn
L FireWire N zero line + V output voltage 0 output midpoint
Q:Where can I buy an actual transformer toy?
Q:Low Voltage Transformer Problems?
Transformers have a generic winding and a secondary winding. they are wound with a ratio in recommendations. The ratio is the secondary divided by skill of the common. occasion: a generic winding of one hundred turns and a secondary with 10 and a hundred and twenty volts on the common : a hundred and twenty * (10/one hundred) 12. this might grant the needed output voltage needed. some transformers have distinctive faucets so which you would be able to get distinctive voltages from the a number of connections. in case you're desiring greater effective than 3.9 volts, you will be able to desire to purchase one which has the splendid voltage.
Q:Need help designing a small transformer?!?
Transformers follow Ohm's Law and multiply or divide voltages based on the number of turns making each coil. You need only ensure your two coils have the appropriate number of windings. As for actual numbers for the windings, 1.5mA is an absolutely tiny amount of current, so you have considerable flexibility in this. If you are looking to build a transformer, you should look up the information on what you're planning to use for a core, to be able to calculate the voltage across the secondary coil.
Q:100kVA above the transformer grounding resistance is how much
National specifications for electrical equipment grounding resistance requirements: 4.1.1 parallel operation of the transformer and other power equipment capacity of not more than 100 kVA, the grounding resistance should not exceed 10 Europe.
Q:AC Transformer & Circuit Board Problem?
The Sandshark nailed it. Tell your handy man he's on the hook for the 3rd control transformer AND the 2nd circuit board. Then tell him to hit the bricks. Now do what you should have done in the beginning; call a qualified, COMPETENT technician.
Q:voltage transformers help!!!?
If you want to step 12 volts AC to 96 AC, you need a transformer with a primary to secondary winding ratio of 8. You then connect the 12 volts to the secondary, and will get 96V at the output. The most accurate way to do this, is go to a transformer shop and ask them to do this. They will ask you for current requirements. If this is not an option, go to a hardware store and ask for a 120V to 15V (or whatever value is closest) transformer. Keep in mind that while voltage is multiplied, current is divided, so that at the end you get the same power. So, if you have a transformer with n8: V12*896 volts I 110/813.75 amps
Q:Rated capacity of three-phase transformer S = √3 * U * I
So, when calculating the three-phase load, U is the line voltage, and I is the line current. S = 1.732 (root 3) UI. S = 3UI. Where U is the phase voltage and I is the phase current. S = 1.732UI where U is the line voltage and I is the line current. Two methods, the same result.
Q:What continuity is Transformers Prime in?
Transformers Prime is set in a new continuity family, launched recently by Hasbro and also includes the War for Cybertron video games. It's really complicated, but in short, you only need to know that you do not need to watch, play or read any previous Transformers material to watch this series. Even the War for Cybertron games, which are supposed to be in the same continuity family, actually clash with the events of the TV series to the point that they're effectively a separate continuity. I myself have not played the game and it's perfectly fine. Also, I've provided links for the ultimate Transformers wiki so that you can do research on whatever aspect of the Transformers universe that you want. Don't worry, the show is fine to watch from the Darkness Rising: Part 1
