Question 35) #Insulator are generally made of

(A) #Glass

(B) #Porcelain

(C) #Cadmium

(D) #RCC



Correct answer (A)

Both option (A) [GLASS] and option (B) [PORCELAIN ] is correct and the answer given by SSC is option

(A)

That is glass.


#Why Ssc has given the answer glass instead of porcelain?

#Dielectricstrengthofporcelainis60KV/cm

#Dielectricstrengthofglassis140KV/cm



#Advantagesofglassinsulator
-
It has very high dielectric strength compared to porcelain. Its resistivity

is also very high. It has low coefficient of thermal expansion. It has

higher tensile strength compared to porcelain insulator.

Disadvantages of Glass insulator

1) Low tensile strength due to brittleness of Glass ( can not used in

transmission system)
