Ceramic line post insulator polymer is made of wet process porcelain, Manufactured and tested to ANSI Standard C29.7, and is non-puncturable design.

Ceramic line post insulator polymer properties:
Short, sturdy sheds, Small Diameter
Thermal Mechanical Test w/ Cantilever Load
Rated voltage: 20kv, 22kv, 24kv, 25kv, 30kv, 33kv, 35kv, 36kv, 45kv, 55kv, 66kv, 69kv, 88kv, 132kv
Models: ANSI 57-1, ANSI 57-2, ANSI 57-3, ANSI 57-4, ANSI 57-5, ANSI 57-6 , ANSI 57-11, ANSI 57-12, ANSI 57-13, ANSI 57-14, ANSI 57-15, ANSI 57-16, ANSI 57-21, ANSI 57-22, ANSI 57-23, ANSI 57-24, ANSI 57-25, ANSI 57-26, ANSI 57-31, ANSI 57-32, ANSI 57-33, ANSI 57-34, ANSI 57-35, ANSI 57-36

All units of ceramic line post insulator polymer are manufactured from high strength alumina porcelain and are smaller in diameter, lighter in weight and more resistant to impact damage than line post insulators manufactured from standard strength silica porcelain.
