Compression Testing in Insulator Quality Control
While tensile and bending tests dominate insulator mechanical testing, compression testing is essential for specific insulator types — particularly station post insulators that experience compressive loads from busbar weight and short-circuit forces. Compression tests also verify the quality of concrete poles and foundations used in substation construction.
