Line post insulator ngk

 Line post insulator ngk is a special insulator, it is used on high voltage overhead transmission and distribution power line.

Line post insulator ngk

The main function of line post insulator ngk is support and fixed wire to keep a distance between conductor and earth, line post insulator ngk also prevent electrical current back to the earth.

Since the line post insulator ngk used on the high voltage power system, so it nee line post insulator ngk have a high quality on Electrical strength and moisture resistance properties.

The voltage of Line post insulator ngk can reach to 132kV, it also used with a spindle rigidly on supporting structure, the spindle of line post insulator ngk can divide into two types, long spindle and short spindle.

Compare with pin insulator, the line post insulator ngk have some difference, Line post insulator ngk is non-puncture type insulator and it can used on a higher voltage than pin insulator.

Line post insulator ngk have four different type according to structures, and different structure can meet various requirements.
◆ Vertical tie-top types
◆ Vertical clamp-top types
◆ Horizontal clamp top-cup base types
◆ Horizontal clamp top gain base type

Composite line post insulator ngk have two colors for clients to choose, red and grey, the composite line post insulator ngk have several advantage compare with porcelain/ceramic insulator:
◆ Good mechanical properties
◆ Good resistance to soiling and flashover
◆ Good resistance to corrosion
◆ High efficiency operation
◆ Excellent pollution performance
◆ Lightening weight
