Why do High Voltage Ceramic Insulators have Discs? | An In-Depth Exploration

This has some real How It's Made vibes. Unbelievable you're at <1k subs. Hope you get some well-deserved recognition.

Sounds like the guy that was on how it's made..on tv....

Electrical engineer here. No need to watch the video - discs offer the best cost-effective way of insulating, as they are very good at separating water droplets from forming a path for electricity and this is of course the main concern since oxygen is a very good insulator. My diploma was also about measuring the parameters of ceramic insulators.

Yes of course , we ( engineers ) know about this .... but ..... the ( secret ? ) reason is that the ceramic industrial pottery folk do this to show off their skills ( a simple smooth tube would look SO BORING ) .. Ha - Ha ......... DAVE™🛑

pls be vegan animals also have lifes Radhe Radhe

Although the ones you're showing when you're saying ceramic insulators are actually glass.

more commonly called cup and saucer insulators. Glass insulators are slowly replacing the ceramic ones because of their better and more predictable characteristics.

Today, glass is the choice in suspension; 70 year life exceeds that of porcelain at 40 years.

They had a lot of those tea saucers leftovers and used the . Get a brain

They are a stack of discs instead of a smooth straight ceramic pole because it effectively increases the surface area and effective distance between the two ends.
Electrical flash over follows the surface, so a 1 foot long disc insulator provides the equivalent of a 5 foot separation

I enjoyed the 8 minutes of something I already know, but still seeing them manufactured is fun. You should create a series "How Its Made" LOL !

How do y'all hold these stacked ceramic boogers together fellers? Looks like your "deep dive" didn't go quite deep enough for me...

I always thought the disc design was to prevent rodents from climbing up and chewing on the wires.

Flying saucers.

Now I understand the reason for the disks. Makes so much sense. Don’t know why I didn’t think of it myself.

Those ceramic discs are there as hand and foot holds for the METH " scrappers " to get that sweet sweet METH " scrap metal " that the power company just left hanging out there in the wild for them to claim to get their fix each day

I’m pretty sure the porcelain insulators came long before glass ones. I’ve seen old film of them making porcelain insulators in the 1920s.

Am Not a Electrical Engineer
Yet The Disc Shape of The Insulators Is Specifically Designed To Defuse
The Electrical Field….
The High Voltage Does Not Travel Through The Electrical Cable
The High Voltage Travels Around The Electrical Cable Which Creates a Electrical Field
So When The Cable Is Held Up By a Tower The Insulator Defuses The Electrical Field at That The Junction Point
You Don’t See This Yet You Hear It
If You Stud Under a
High Voltage Tower on a
Foggy Day You Hear The
Insulators Working or a
Hum This Hum Is at
60 Cycles or 60Hz and
This Hum Is More Pronounced By The
Insulators Because The Disc Shape is Designed To
Defuse The Electrical
Field at Those Junction
Points…..
Other Wise You Have
Two or Three Electrical
Fields Crossing Over Each Other and We Don’t Want That
Remember The High Voltage Travels Around
The Cable
Not Through The Cable and So That’s Why The Electrical Field Must Be
Defused or Broken Up at The Junction Points

Remember
Am Not a Electrical Engineer

What a fun channel.

The number of insulator cups is a rough way to estimate the voltage being carried by the conductors. Longer insulators equals higher voltage.

AM Broadcast towers utilize ceramic insulators at the base of the tower. The whole tower is energized with RF energy, where the insulator keeps it from contacting ground potential. Their appearance is different than what is utilized on high voltage electric transmission lines.

I saw mostly glass insulators being used on the towers.

Sound signature... If set of disc seperate by invreasing distance and size so it echo sound wave increaseing frequency according to (target distance over speed of sound) can ambilify sound to target

Narration said something about using ultrasonics to clean surface of insulators. I really doubt that is ever done.

Thank you for this video

Polymer shed insulators are alsom used commonly now.

Ceramic insulators were used for telegraph lines as far back as the 1840’s Both earthenware and porcelain were used. Glass was used on local lines as it was cheaper. Glass was used in the USA during the Civil War as porcelain could not be imported from Germany due to sanctions. When electric supply commenced both materials were used. Insulated bushings on transformers, circuit breakers and bus bars used for medium and high voltage service were always porcelain.

Very nice video

What is the salary of an engineer who tests these insulators with hundreds of thousands of volts and then certifies them as good or bad?
