Temperature Cycling in Insulator Standards
Temperature cycling tests are specified across multiple IEC insulator standards. They verify that the insulator materials and interfaces can withstand repeated thermal expansion and contraction without degradation. This is particularly important for composite insulators where polymer housing, FRP core rod, and metal fittings have different thermal expansion coefficients.
