Station post insulator TR205
Station post insulator TR205 is one of the most commonly used type and designed and produced according to ANSI C29.9. It belongs to 15kV porcelain station post insulator. The color can be brown or gray.
Station post insulator TR205 and other type porcelain station post insulators’ low maintenance operation and superior electrical and mechanical characteristics make them the ideal choice for high voltage switch and substation bus support applications.
Station post insulator TR205
As one of famous porcelain ceramic insulator supplier, station post insulator TR205 produced by us meets or exceeds all ANSI standards in both electrical and mechanical characteristics for its voltage class. For the porcelain part, normally we used C110 and it can meet the mechanical strength very well. Since station post insulator TR205 has two metal parts top and bottom and for this type high voltage insulator it has very high demand for the height, so the assembly one is difficult to control. But for us, we have skilled technical workers and more precise plastic rack. We can well meet the height requirement.
