Distribution line pin type insulator is normally used on distribution lines, made of porcelain or silicone rubber materials with high mechanical strength.

According to insulator materials, distribution line pin type insulator can be divided into
◆ Porcelain pin insulator: made by porcelain
◆ Polymer pin type insulator: made by silicone rubber
◆ Glass pin type insulator: made by glass

Porcelain distribution line pin type insulator can be made by wet process porcelain and dry process porcelain in accordance with ANSI C29.5 and ANSI C29.6 standards.

Polymer Distribution line pin type insulator can be made by molding in accordance with ANSI C29.1 and IEC 61109 standards.

Glass pin insulator is usually used in Russia for supporting and insulating wires.

Polymer distribution line pin type insulator can be divided into
◆ Tie top pin insulator
◆ Clamp top pin insulator

Distribution line pin type insulator is one main kind of low voltage insulators used for 11kv, 22kv and 33kv power lines.
