Disc suspension porcelain insulator made by wet process porcelain is designed in 11kv and used in suspension strings for any voltage levels power lines.

Disc suspension porcelain insulator is made of porcelain materials and also more prone to damage caused by corona activity. Disc suspension porcelain insulator is also called dead end insulator used on dead end towers.

For the purpose of electrically isolating these line conductors from the support structure as well as providing mechanical support to them, insulators are used.

Disc suspension porcelain insulator is usually used on LV, MV and HV transmission and distribution lines for supporting and insulating conductors. Porcelain pin type insulator is also used on MV and LV power lines, can exchange disc insulator in some conditions.

Most of the insulators are often under high electrical as well as mechanical stress. The ever increasing demand for electrical energy worldwide has led to the use of even higher system voltages for power transmission. For instance, China has completed the construction of a 1000 kV ac system.

Because of the development of electrical systems, more and more Disc suspension porcelain insulators used on power lines
