Line post insulator specifications

 Line post insulator specifications are widely used on transmission and distribution line, Line post insulator specifications play an important role in power system.

Line post insulator specifications          Line post insulator specifications

Since the different need of the line post insulator specifications so there are two different material of line post insulator, the traditional material of line post insulator specifications is porcelain which can be called ceramic too, another material is composite polymer,

Compare with porcelain insulator, composite polymer line post insulator specification have many advantage:
◆ Good mechanical properties
◆ Good resistance to soiling and flashover,
◆ Good resistance to corrosion,
◆ High efficiency operation
◆ Excellent pollution performance

Line post insulator specification have different types of structure, it can be classify into four different types according to the structure:

◆ Vertical tie-top type line post insulator
◆ Vertical clamp-top type line post insulator
◆ Horizontal clamp-top cup base type line post insulator
◆ Horizontal clamp-top gain base type line post insulator

With all these different structures line post insulator specification have many advantages, Available in both horizontal and vertical trunnion, Horizontal used for applications such as down-leads and jumper loop control, Vertical used for applications such as crossarms and structures,
