Composite Station Post Insulators
Product Description
Composite Station Posts (CSPs), which were first introduced during the early 1980s, consist of a solid core made of fiber-reinforced polymer (FRP) and an elastomeric housing. The typical diameter of the FRP core ranges from 45 to 100 mm, with maximum diameters rarely exceeding 130 mm. The application of CSPs in substations stemmed from the past use of composite line post (CLP) insulators, primarily in the United States. CSPs with solid cores are typically employed in voltages up to 245 (420) kV. However, their broader application is limited for higher voltage classes due to relatively high mechanical deflection. The test standard for this product is IEC 62231, while mechanical and electrical characteristics are defined in IEC 62231-1. This standard also encompasses ANSI types used in North America, with C29.19 being the relevant standard for such ANSI types.
