Name: Disc insulator suspension type
Type: ANSI 52-3 Disc insulator suspension type
Related type: Voltage Range: 11kV~220kV
Standard: The ANSI C29.2 standard
Graze colors of insulators: Brown or light gray
Mechanical failing load: 70kN,100kN,120kN,160kN,210kN,300kN and as per client’s request
Material: Alumina and silica porcelain
Application: Overhead lines and transmission lines
Disc insulator suspension type ,this type of insulator also acts as a conductor to protect the overhead transmission line. Porcelain material is commonly used in the manufacture of insulators. This includes a string of single or insulating discs hanging on the tower. This insulator operates at 33KV and removes the boundary of the pin-type insulator shown below.
