Introduction

Porcelain Pin post insulator is puncture insulator normally made of porcelain material, commonly voltage 20kv, 24kv, 33kv. Porcelain Pin post insulator has a big sheath to increase creepage distance and has the advantages of pin type insulator and line post insulator and enables the insulator used on heavy contamination areas. Porcelain Pin post insulator is one of line insulators, which is an assembly of one or more shells, having means for semi-rigidly supporting line conductors.
