Product Description

 

Product Description

ANSI 56-1 porcelain ceramic pin insulators

As the name suggests, the pin type insulator is mounted on a pin on the cross-arm on the pole. There is a groove on the upper end of the insulator. The conductor passes through this groove and is tied to the insulator with annealed wire of the same material as the conductor. Pin type insulators are used for transmission and distribution of electric power at voltages up to 33 kV. Beyond operating voltage of 33 kV, the pin type insulators become too bulky and hence uneconomical.

§ High Quality insulator-Annual production of various types of insulators 3 million pieces.
§ Factory was established in 1998, continuous technical development and improvement, technology and process strength.
§ 25 years of State Grid, China Southern Power Grid quality supplier.
§ 25 years of experience in insulator export production
