Systematic qualityOil-immersed distribution transformers from Siemens are manufactured in accordance with our quality management system – certified to EN ISO 9001. Compliance with important standards, from IES to VDE, is a matter of course, just as much the exclusive use of high –quality materials. Qualified employees implement the demanding standards in daily practice. So , quality is the logical results of universal philosophy.
DescriptionDistribution Transformers are used to convert electrical energy of higher voltage; usually up to 36 kV, to a lower voltage, usually 250 or 435 V, with an identical frequency before and after the transformation.
DetailsRated power of Liquid-immersed Distribution Transformers:50 to 2,500 kVA normal distribution application / 2,500 to 6,300 kVA for special industrial application
Rated voltage:HV side: 6,000 to 33,000 V; LV side: 200 to 1,000 V
Other types of Liquid-immersed Distribution Transformers:• Single-phase pole-mounted / pad-mounted Distribution Transformers 10-250 kVA• Three-phase pad-mounted distribution transformers 300-3,000 kVA• Submersible Distribution Transformers 25-500 kVA (single-phase); 100-1,000 kVA (3-phase)• Step-down-transformers: up to 500 kVA (single-phase)
Application:suburban areas, public supply authorities and industrial customers
Advantages / characteristics:environmentally friendly desing with MIDEL®-filling, free of maintenance (Tumetic design), low losses, low noise, long operation life time.

Oil-immersed distribution 630-KVA transformer TUMETIC:View into the inside
1- Core and windingsBoth are held together by a pressed structure and bolted together with the tank lid. The complete unit can be lifted out of the tank.
2- CoreHigh-quality electric sheet steel, most modern core design and optimized lamination provide for low-loss and noise- optimized operation. 3- WindingsConstruction and materials guarantee a long service life.
4- Tap changerUsed to adjust the ratio to the local voltage conditions. It can be adjusted from outside in de-energized condition.
5- Low –voltage bushings
6- High- voltage bushings
7- Thermometer bagImportant accessory for temperature monitoring.
8- TankThe TUMETIC design shown here is hermetically sealed. Elastic corrugated walls take up the volume changes of the transformer fluid.
9- TruckPlain transport wheels can be aligned for longitudinal or transversal movement.
10- ConservatorIn the TUNORMA type, it is equipped with an oil level indicator and a filling socket.
11- Corrosion protectionThe surface gets a multicoating in the standard color cement gray(RAL 7033). Special colors or galvanization are possible.
