The pin insulator gets its name from the fact that it is supported on a pin. The porcelain insulator is also a one-piece insulator when used with low-voltage lines but will consist of two, three, or four layers cemented together to form a rigid unit when used on higher voltages

33kv porcelain pin type insulator is made by the wet process，it uses high grade ceramic . The porcelain is sound, free from defects, thoroughly vitrified and smoothly glazed. 33kv porcelain pin type insulator mainly used in high-voltage power distribution lines.
