As one of important ceramic pin insulators products, IEC PW-22-Y porcelain pin type insulator used on overhead lines in the voltage range 20kv to 25kv , and which manufactured and designed in accordance with pin insulator specification. The ceramic pin insulators are also used more specifically to refer to insulating supports used to attach electric power distribution to utility poles and electrical power system.

IEC PW-22-Y porcelain pin type insulator or ceramic pin insulators application:
Perfect ceramic pin insulators do not exist; because a portion of the ceramic pin type insulator could become electrically conductive if the voltage applied across it exceeds the punture voltage. This is known as punture voltage of a ceramic pin insulator. IEC PW-22-Y porcelain pin type insulator has high resistivity, are very good electrical insulator.

Pin insulator specification:
ANSI: American national standards institute
IEC: International Electrotechnical Commission
AS:Standard Australian
BS: Britain Standard Institute
DIN: Deutsches Institut für Normung e.V. etc.

IEC PW-22-Y porcelain pin type insulator technical parameters:

IEC PW-22-Y porcelain pin type insulator or ceramic pin insulators manufacturing process:
As long as the manufacturing process for IEC PW-22-Y porcelain pin type insulator has important six steps. Firstly, we could suitable clay, the step is very important for producing Pin type porcelain insulator. Second step is filtering clay and vacuum puging, drying. The others are shaping, shaping, apply sand and firing.
