Unbelievable building process of 100 KVA electric Transformer inside the factory with expert technique. For Contact: Gmail : fraz.raw@gmail.com Facebook : / skillsunit1 Channel Url : / skillsunit1 #transformer #manufacturing
"Skilled " ? The workmanship is worse than Africa. There is no skill. Horrific practices.. as an hvac trainer i had better soldering skills than these guys.
Proud of Pakistani Engineers. What a great team work. The quality of work and products are amazingly of high standard. Thank you for sharing. I liked this video
Quality? In terms of quality there aren't many scopes to make this worse. Maybe if they switched to aluminium and then tried to use tinsolder it then it would be worse than this.
Most amazing process to see happen. Something everyone takes for granted, with so many skills involved to manufacture. Thankyou so much for this wonderful video.
Thank you for a very informative video, very interesting. I am a retired electronics engineer, not heavy current, so this is interesting to me. I used to be head of an R&D department designing and building 5kW VHF TV transmitters, 5kVDC HT, also VHF FM.
Bro soon the people will find out the new energy sources. And energy will be cheap. Just imagine that humanity will generate the energy from space like Tesla said.
I assembled and welded transformers almost like these 40 years ago. Our sheet metal was all rectangle pieces that interlocked and were square to each other. The corners should be like a deck of cards on the corners. The wires were mig welded with aluminum, not soldered.
Finally. After long time not faked video. Real work. Congratulation. Please keep on and show how is it made in your country. Clean spaces. Good technology. Clean dresses. ( Maybe only for this video.) Last question who is the old man in light blue dress sitting on the bed ?????? Owner supervisor boss ??? Thank.
I love that solder technique with a cutting torch ! I have to learn that trick. Think they can do aluminum with that cutting torch ?? Think i will junk my tig welder.
I have seen the manufacture of a power transformer in Pakistan starting with winding the secondary, the primary, making the core, using the insulating materials on the windings, the tank that's clean and corrosion proof, the oil that's put through a drying machine to get the moisture out, the bushings installed the windings soldered and brazed, all done in a clean, dry room, assembled with nuts and bolts with the transformer spray painted. Looks like they have done a great job of this. The testing and installation not shown in this video.
Have not seen a new oil filled transformer around this KVA in over 35 years in the USA. Dry type that have ecpoxy coated windings made in a vacuum chamber far superior. Had these cavemen style transformets back in the 1970's and you had to have a company come out and test the dielectric of the oil then if it was low filter it for
Thinking about same thing. I am 100% sure that they did not process any preventive oil maintenance. But what i think is worse are these high-voltage joints inside, that looks very random how these welds will survive in longer time. Their advantage is stable temperatures, this will not operate like minus 20 to plus 40 degree Celsius for a years.
It’s all about demand and supply if the customer pushes the issue these guys will have to invest in vac. Chamber and related equipment and at least Mag test the windings here in USA capacitive transfers are most popular small in size and lightweight they are doing a great job for what they know with limited resources ❤❤
It is wonder that they can make such a high power product without any testing! And they can do it all while wearing safety sandals! Amazing! I wonder what the product failure rate is?
They probably test them . Expensive equipment, with high demands on operational performance . the client dont want a faulty one. Mayby someone else does it of site. Cant imagine that the would put them to use untested, you want to know forhand, before puting high current; if they are faulty
@@balisharif1742 Without high-voltage power-on testing, the failure rate of the product cannot be controlled. Used on projects may cause greater losses.
Ma sha ALLAH. You all are doing wonderful job. Keep it up. Very soon you have the potential to become a Great Practical Engineering Company of Pakistan. I spent more than 36 years in Siemens Pakistan and Germany. Please let me know if any practical guidance is required Free of Cost for brave Engineers. Once again Continue your work. ALLAH will definitely help you all who are Honest and Hardworking to the organization and Country.
Your Well Wishes are highly appreciable this Video is a Heart Touching one as I have also been Working in Prime Engineering Works Lahore in manufacturing of Power Transformer Shell / Bodies of up to 100 MVA Capacity complete Fabrication Inspection and Testing. I Dua for Up raising and Progress of this Industry.
Assalamu Alaikum Dear I spent 3 years in simiens Pakistan 1979 to 1982 in transformer winding section if I remember that was called shop 20. Mr. Sperber was the GM.
@@nationalist6611 Mr Hans Sperber was a devoted person for the cause with excellent character to promote COMPETENCE culture in engineering industry from bottom to top and vice versa. Most of the time early morning before 0730 , he used to welcome at double iron main gate. Every family and society needs Role Model and he was one of them with reference to Work Moral on shop floor.
@@khalidjamalsiddiqui895 Yes I remember. One day I was on ht winding machine and winding a 25 KVA coil I didn't know that Spurber is standing behind me suddenly he came near to me and with his smile he appreciated me.. He usually reached the company at 7:30 am. What a golden time.
@@nationalist6611 Appreciation of good work always boost further advancement as Value addition and creation of Self confidence. Thanks. Have a great time.
wonderful video, quite informative. i really liked it so much. however the part is missing where they should test the working of transformer by giving input 11kv and checking three phase output of 220v
This seems to be the steps in there production , I think these are made the same way everywhere, the only Worker hazards I saw was the lack of protection shoes, and that th speay painter had bad protection from fumes, a over pressurised whole face mask ,hood would be good to implement in the factory. Good that there are a paint room with fans in doe. Ohtervice seemingly okay working environment. Steps: 1 Bending tabs for secondary low voltage side windings. ( The flat copper bars) 2 Building inner layer of insulation paper for secondary windings. Winding up secondary winding 3 adding insulation to spool. 4 making primary high voltage (the small copper wires ) Winding ( almst same steps as secondary w) 5 stacking the windings 6 making iron core for transformer Plates are stacked and pressed together, in the bottom with clamp . And iron core insulated were windings will sit. 7Windings put in place and top section of core mounted an clamped . On dry,; small transformers the core is often welded together but I guess that clamping allows for easy access without the use of dirty grinding if windings need replacement. 8 Terminals prepared for all connections to insulators. The moving bar in the is a switch to turn of The transformer. The oil in the unit reduces arcing when switching is done. 9 top plate is fitted with isulaters. Core anchored (insulated from it I would guess )to top plate and Windings attached to switch. External isolaters connected to switch. 10Insulation oil is heated to remove all moisture, the machine is a plate heat exchanger or maybe a filter stack (a bit unsure here) .The oil is filtered however to remove unwanted contaminants, that can cause arcing. Over time the oil may need replacement because switching the unit on of will make the oil dirty = conducting over time, 11 the internal unit is heated to remove moisture, in a owen,the oil Is filled in the" tub" and the internals put into it. Not the self circulating feature on th le cooling fins ! Neat! 12 the " tub" with cooling fins ,the top Unit with the (expansion reservoir ) Are spray painted, note that the isolaters are covered to prevent paint on them. 13 the connections are colour marked, I would guess that the white tab on the low voltage side is neutral (connected to iron core?) and the other are ph 1 ph 2 ph 3. The high voltage side is insulated has only phase connections. The bent unpainted rods are lightning gaps ,to let lightning go to earth connection on transformer( the metal shell) The grey paint in the upper side of the folds on the high voltage connections is some form of treatment to increase insulation value on it I think.. The content creator or someone else may correct me if a have misunderstood something in the process. It okay if you do . The "blue bottle" is filed with sica gel to prevent moister build up in the oil that may cause arcing in the unit.
Они собирают магнитопровод при помощи киянок. Скорее всего, контора экономит на нормальной электротехнической стали, что самым негативным образом сказывается на характеристиках выпускаемых изделий.
за то пофиг на корозию на пластинах и отсутствие герметизирующей прокладки между баком и крышкой, через щели которой очень быстро внутырь будет попадать атмосферная влага. ну за то без работы не сидят.
@@Neko-Neko-nian как это нет прокладки ? На 19:33 - нет, а на 20:03 - уже есть. На крышке приварен расширительный бак и в нём тоже присутствует масло, если б там небыло прокладки, масло из бака убежало бы из под крышки.
Primitive methods at best. Look at misaligned cores. Fantastic knife to peel insulation . Lenz and ohm must be rolling in their Graves. Transformer contacts are ne er soldered, either spot welded or crimped
They are still using unctuous technology. These types of factories are obsolete. No insulation or sufficiency test. This type of iron core has a high noise-heating ratio and high power factor. Now I wonder why Pakistan's power structure is so poor and often nationwide blackouts. That soldering has a very high risk of breaking. Spot welding is done instead. But, good everyone is employed.
im sure if these companies actually started paying for injured employees long term health they would care to enforce some basic safty rules... like wear freakin boots..
