I've been wondering why insulators have been shaped like this since I was a kid and finally the algorithm points me to a useful video explaining why!

When I was young I used to wonder why tea discs are hung on high voltage lines. Today I think back to my childhood and am ashamed of my stupidity.

They used to be made of glass and come in different shapes and colors. My great grandmother used to collect them and had all sorts from the early 20th century.

[@laurisikio]

Is there anything grandmothers don't collect?

[@duroxkilo]

my uncle worked in an insulators factory and i still remember the feeling of touching the smooth cold insulators. all kinds of shapes and colors, some small enough to fit in my pocket and some much taller than me... i was fascinated by them as a kid but i was also afraid of them because of my grandma's stories of those insulators being dropped, shattering and blinding people. the facility where they were testing the insulators was scarier than hell for me. workers were wearing full body rubber suits, skull and crossbones signs everywhere and the sound/smell of electric arcs... in my mind everyone there was basically a knight in dark armor fighting invisible evil dragons :}

[@thetruthexperiment]

I have never visited an uncle at work. Sounds like a caring family.

[@duroxkilo]

@@thetruthexperiment thank you. those were fascinating times... it did feel like i had 4 mothers and a few dads if i think about it. :} they would take me everywhere, from visiting castles to a tour of the cement factory... especially my grandfather, the king of factory tours and hours long explanations. the guy was nuts, he knew everybody in that town and acted like he owned at some point each of the factories... he would just walk in everywhere. like just a casual visit to the 'chemical plant' to check stuff out. maybe catch up w/ some buddies, maybe get some more knowledge but basically show me all kinds of things he found interesting at that particular point in space and time :}

[@dirtymike4894]

I am also an engineer. I am glad to see that you mentioned that you are an engineer first. It is an unwritten rule that we are first supposed to identify ourselves as engineers in every conversation. 🤣 For example, if you are walking your dog and someone says, "What I nice dog you have." You should say something like, "Well, I'm an engineer, so when I look at dogs I see their functionality as the beautiful part. Like protecting my home, chasing away rodents, etc."

[@sarathkrishna5109]

In my early career days I used to climb on transformers to clean the insulators. It was part of weekly maintenance. They are a vital part of electricity as we see it today. There are many forms of insulators like glass, sfp gas, etc depending on the application. Good to see videos on this topic.

[@harishchalwadi]

Brilliant ! Always wondered why were they designed in that particular shape.

[@lambdaprog]

This channel is quickly becoming the ultimate reference for engineering animations.

[@Whatifffff]

Wow 😳 we miss the engineering and science in everyday things we see😕

[@abdulhakim4639]

I thought the insulator discs was only to prevent leakage because of raindrops. It's also crucial to prevent the spark because electric field.

[@EvilBrit89]

They also stop arcing between screwed connetions on each end of a line..

[@vanphan9318]

It is both effects.

[@m7dtbh580]

Did you know high voltage power lines don't have any kind of insulation?

[@haruhisuzumiya6650]

It prevents ionizing arcs in air

[@thatonelonelyeagle5398]

This video seriously helped answer my question of why they are shaped that way! They are great collector items as well due to their unique shape and styles.

[@motorsportislife9598]

In fact, the metalling ring in some cases has another scope: bypassing the isolator in case of lighting stroke on the power line. That's because when a lighting stroke occur on the power line the voltage reached is much higher of the nominal voltage of the power line and that can damage the isolators and the others components working on the line, the ring in that case act like a conductor that allow an arc to the ground through the metal pylon that is always grounded. Of course the distance between the metallic ring and the pylon is calculated to allow a bypass only when a certain voltage is reached

[@InvincibleArts]

Yes the guard ring.. It's compensates the earth capacitances and also provides the path for flash over current by protecting the insulators.. And this will also be shared with the lightning arrestors.

[@MysticX_X]

i was wondering why in the suspension insulator they uesd metal clips and not some insulated material

[@InvincibleArts]

@@MysticX_X To provide mechanical strength💪. Even though it's a conductive element, metal is the most efficient thing to put there when taking other aspects into consideration.

[@MysticX_X]

@@InvincibleArts Yeah that makes sense, thanks

I jumped onto youtube on a Saturday to watch iPhone 14 videos but have been watching Lesics' videos for the past 2 hours. Not how I planned to spend my weekend and am glad I'm spending it this way. Great content!

[@Ryuseigan]

The contour shape of the Insulators, i.e the umbrella shape helps to reduce the surface charge density.

[@m80116]

I love the old white ceramic bell type (not represented here) and bottle green glass ones. They remind me of the 60s and 70s, the economic boom of my country and the power grid reaching for the first time in history the countryside. I sometimes shoot them with my cameras and I've even made an homage piece of Magritte's art that reads "Ceci n'est pas un isolant"

[@johnniewalker39]

BEST EXPLANATION EVER!!! I've been looking at them since i was a kid and never understood what they do. SUBSCRIBED!

[@nischalchhetri7445]

When I was kid, I thought they were just big plates and had no use at all. It's amazing to know about it after a decade!

[@thatonelonelyeagle5398]

Same! I wondered why the heck they would put plates and bowls up there to hold the wires and not just a cylinder isolator of some type! Used to think they were up there because restaurants no longer wanted old plates and the landfill was getting so sick of seeing them in the fill so they bolted th together and strung them up on power lines to make use of unwanted plates! It led me to collect over too many of them from sales, auctions and pole change outs while meeting some great friends with great knowledge and history for these insulators! They are very intriguing pieces of technological art!

[@uriituw]

Great video. I actually learned something! It ended a bit abruptly, however.

[@nick8231]

[@rayoflight62]

Every "umbrella" disk provide 15 KV AC of dielectric insulation. A 220 KV 50 Hz line uses insulators with 20 - 22 disks. There is a mathematical formula which optimise the number of disks, their size, and their spacing. Insulators usually include a safety factor of up to 50% to counter the effects of inductive loads, overvoltage, and lightning strikes. The insulators on HVDC power transmission lines have a different composition and a different design, because they are less subject to capacitive losses, but more subject to ion migration. Thank you Lesics, for this great video...

[@sagondaliya28]

[@Vinline1995]

when I was a kid I had a weird interest in transmission towers( I still have). I grew up next to a substation so I'd always see them every day. When we were moving out, I asked grandma to get me to the large park because there was a massive tower. And there I found a broken insulator next to the tower. I think it was there because it was old and they changed it. I brought it home and washed it then kept it for myself

[@ethanhunt2263]

im both happy and shocked to hear as i was just like you. I had so much interest in transmission towers when i was a kid.. my dad and i used to go to two particular towers that were near our home. One was a 132 kV one and the other 400kV. i could tell the voltage just by the insulator count and all that then. Still they never cease to amaze me.

[@Vinline1995]

​@@ethanhunt2263 That's amazing but I never knew their voltage. But it's amazing to know a person like me

[@gblargg]

I loved electric distribution poles as a kid too and drew them a lot. I remember on a school trip I used all my camera film taking pictures of the power poles along the way rather than at the place were going LOL. My father even let us build some in our large back yard in the country. We put 8-foot poles in the yard with insulators and wire, and I energized it with low voltage. I collected a few of the insulators over the years (still have them in the garage). They are quite large in person. I liked the bell insulators the most.

[@Vinline1995]

Kudos to your dad.

[@borntoclimb7116]

[@minrongchen2479]

This video explains the evolution of the shape of the insulator on high voltage equipment such as transformer or tower. When I was in freshman year, I asked my electric power system teacher why the insulator shape is like many umbrella layers, he just couldn’t explain it, so this video help my find the answer I have been confused for many years.

These bush increase the creepage distance. Creepage is a distance between two metal along the surface of object. In high voltage pcb design we should give proper creepage distance otherwise the pcb will collapse.
