Porcelain Suspension Insulator
◆ The head portion of ball pin and cap are suitably designed so that when the insulator is under tension the stress are uniformly distributed as compression over the pin hole portion of the shell
◆ Disc insulator is designed, manufactured and tested in accordance with insulator standard / insulator specification
◆ Disc insulator and insulator end fittings come in contact with cement
◆ Usually made from porcelain material
◆ Normally used on transmission power lines
Disc insulator can be designed in accordance with ANSI C29.2 and IEC 60383 standards, the code number of Disc insulator
