Explain why it is better to use a glass like silica to insulate high voltage rather than something like a window glass (soda lime silica)

Solution

Pure silica can produce an excellent glass, but it is very high-melting (1,723 o C, or 3,133 o F), and the melt is so extremely viscous that it is difficult to handle.

soda lime glass(silica) is Inexpensive; easy to melt and shape; most widely used glass for windows ,bottles,light bulbs,jars.limitations are poor durability,not chemically resistant,poor therrmal shock resistance.due these conditions it is better to use a glass like silica to insulate high voltage rather than something like a window glass (soda lime silica)
