WINNING® supplies porcelain station post insulators with standard strength, high-strength, and extra high-strength ratings. Porcelain station post insulators’ low maintenance operation and superior electrical and mechanical characteristics make them the ideal choice of porcelain station post insulators for high voltage switch and substation bus support applications for distribution system and substation through 2550 kV BIL.

Strength Ratings:

Standard strength porcelain station post insulators are typically used in all standard high-voltage switch and bus applications. They meet or exceed all ANSI standards in both electrical and mechanical characteristics for their voltage class.

High strength porcelain station post insulators are used when an extra amount of mechanical strength is required for heavy-duty bus and switch projects. High-strength porcelain station post insulators have the same electrical ratings as the standard strength porcelain station post insulators. In applications where there are severe short circuits, high-strength porcelain station post insulators are often used. They meet or exceed all ANSI standards in both electrical and mechanical characteristics for their voltage class.

Porcelain Station Post Insulators according to ANSI C29.9: 

TR-202, TR-205, TR-208, TR-210, TR-214, TR-216, TR-286, TR-287, TR-288, TR-289, TR-291, TR-304, TR-312, TR-362, TR-369, TR391

Porcelain Station Post Insulators according to IEC 60273: 

C4-125, C4-150, C4-170, C4-200, C4-250, C6-325, C6-450, C6-550, C6-650, C8-750, C10-950, C10-1050, C12.5-1550, C10-1675C C10-1800, C10-2100, C10-2550
