Few things to be noted particularly about polymer Insulators , first it's wrong to say polymer is not used in costal areas and due to high salinate , it's about porcelain it damages its surface and require frequent coating of silicon whereas polymer Insulators made of silicon rubber and proved highly effective in costal areas infact lots of coastal areas replacing old porcelain disc insulators to polymer Insulators Second fact that polymer is rarely used in to transmission lines you will be surprised to know that in this decade 2011-2020 80% EHV lines comprising 400 kV and above used polymer Insulators , India's largest transmission utility power grid used polymer Insulators in all its transmission lines in this decade . About life of polymer insulator yes it's less than porcelain but cost wise about 40% cheaper than porcelain
Thank you so much sir for good Knowledge
Nice conclusion
Nice video sir
Your ALL Very informative.
I watch your ALL video
Ur voice is good. U explain in proper way.
Nice Video Sir🥰🥰😍
superb
Very informative video
Good🤝🤝🤝
Great sir
Fantastic sir
Ek no👌👌👌👌
Nicely
Very useful video
ماشااللہ
Priceless vdos incredible
Sir,express feeder kya hota hai aur iske use & purpose kya hai electrical field me.
Iti
Great Video. Well and easily explained
Porcelain one of the best insulotor Or lightingarrester india
Porcelain
Good knowledge from you sir .
Few things to be noted particularly about polymer Insulators , first it's wrong to say polymer is not used in costal areas and due to high salinate , it's about porcelain it damages its surface and require frequent coating of silicon whereas polymer Insulators made of silicon rubber and proved highly effective in costal areas infact lots of coastal areas replacing old porcelain disc insulators to polymer Insulators
Second fact that polymer is rarely used in to transmission lines you will be surprised to know that in this decade 2011-2020 80% EHV lines comprising 400 kV and above used polymer Insulators , India's largest transmission utility power grid used polymer Insulators in all its transmission lines in this decade .

Dimension of electrucal quantities barey video banaiye na sir
Thanks sir great information 🌼
Thank you sir good explained
What's it that the insulator(s) separates the electrical line from?
Porcelain or glass me pocelein hi best he ye btao
Sir g dilectric strength kitni hoti hai polymer ki
Polymer insulator ke one disk ki rating ky hoti h
👍
Sir make video in types of arcing horn in transmission line
Please make video on post insulator
Polymer
👌👌👌
How does the polymer insulator work. Because it's rubber
Rubber is Insulator
Miva vi mention karona ...from nepal
🔥🔥🔥🔥🔥🔥
Some correction needed
The polymer insulators are so ugly
Nice video sir ji
