Porcelain pin post insulator of high voltage
Porcelain pin post insulator of high voltage is made by wet-process and in some countries it widely used for distribution line and other electric power line. Porcelain pin post insulator of high voltage combining the advantages of the porcelain line post insulator and the advantages of the porcelain pin type insulator.
For porcelain pin post insulator, the top part is very like porcelain line post insulator and the bottom shed is designed reference to pin insulator. For this unique structure improved operating characteristics of line posts - more rugged construction, improved resistance to lightning impulse damage. So this type of porcelain pin post insulator offers an economical alternative to line post insulators.
porcelain pin post insulator of high voltage ceramic pin post insulator of high voltage
The end of assembly fitting with a spindle or insulator pin, this type of porcelain ceramic insulator can be mounted on the supporting structure steel cross arm or wooden cross arm. And for the porcelain pin post insulator pin hole, it can be Zinc thimble with thread type and porcelain thread type.
Type of porcelain pin post insulator:
Normal pin post insulator
Anti-pollution pin post insulator
The level of porcelain pin post insulator: 15kV, 25kv, 35kV
We can produce or design this type of high voltage insulator of high voltage according to ANSI standard, IEC standard or customers’ requirement.
