| Note 1: The "vertical layer bending strength" of EPGC42 type is the bending strength measured at 150 ℃ ± 3 ℃ after 1h of treatment at 150 ℃ ± 3 ℃, which shall not be less than 50% of the specified value. | ||||||
| Note 2: One of the requirements for 20s step-by-step boost test and 1min withstand voltage test for parallel layer to breakdown voltage in 90 ℃ transformer oil can be selected. | ||||||
| Note 3: The flammability test is mainly used to monitor the uniformity of laminate production, and the results so measured should not be regarded as a comprehensive indication of the potential fire hazard of these laminates under actual application conditions. | ||||||
