Low and medium pin type insulator is one of main electrical insulator used for LV and MV overhead power lines and designed in accordance with ANSIC29.5 and ANSI C29.6 standard.

The features of Low and medium pin type insulator
◆ Normally surface coated with semi-conductive glaze considered as effective leakage surfaces
◆ The distance over them is included in the leakage distance
◆ Top and wire groove shall seat a mandrel with a diameter of specification inch

The characteristics of Low and medium pin type insulator
◆ Used for LV and MV overhead lines
◆ Can be designed in “N”, ”F”, “J” neck
◆ Used with insulator spindle

According to insulator materials, Low and medium pin type insulator can be divided into
◆ Porcelain pin type insulator
◆ Polymer pin insulator

Low and medium pin type insulator may be designed in 900mm creepage distance with high pollution performance and used in heavy contamination areas.
