LIFENG manufactures a wide range of low and high voltage Pin Type insulators designed for distribution systems, highly resistant to lightning puncture.
Pin insulators of one piece or multi-piece construction are widely used in low cost distribution lines. Multi-piece construction makes these insulators less vulnerable to damage as with one shell broken a multi-piece insulator can normally withstand the line voltage for a considerable time without difficulty.
Low & Medium Voltage Pin Type Insulators technical data
Note: The left side of slant is Comman glaze, The right side of slant is semiconductor glaze.
Porcelain pin type insulator or distribution ceramic pin insulator definition:
Porcelain pin type insulator, also called distribution ceramic pin insulator, consists of asingle piece of ceramic or maybe two pieces of ceramic components permanently assembled together by cement. Porcelain pin type insulator is mounted rigidly on a supporting structure by an insulator pin or insulator spindle. Unless otherwise stated, this item does not include the insulator pin.
Insulator pin or pin insulator spindle of distribution ceramic pin insulator:
Small steel head and big steel head spindle according to BS3288, used with porcelain pin type insulator with zinc thimble.
Lead head insulator pin or spindle according to ANSI C29.5 and ANSI C29.6, to suit ANSI standard porcelain thread type distribution ceramic pin insulator.
Porcelain pin type insulator voltage: 11kV or 12kV pin insulator, 15kV pin insulator, 22kV or 24kV pin insulator, 33kV or 36kV pin insulator.
