Pin Type Porcelain Insulator ANSI 56-2

Type:
ANSI 56-2

Overview:
ANSI Class 56-2 Porcelain insulators are used in medium voltage distribution lines and overhead distribution substations. They are designed to withstand adverse environmental conditions such as sea breezes and chemical elements present in industrial areas.
They also withstand the thermal, dynamic and electrical stresses caused by possible short circuits, maximum operating voltage and over voltages.
