Table 2: The technical requirements
No | Property | Unit | Normal value |
1 | Flexural strength perpendicular to layer direction | MPa | ≥100 |
2 | Impact strength parallel to the layer direction (Charpy method) | kJ/m2 | ≥6.0 |
3 | Electrical strength perpendicular to the layer direction at 90±2ºC transformer oil | MV/m | Refer to table 3 |
4 | Breakdown voltage parallel to the layer direction at 90±2ºC transformer oil | kV | ≥20 |
5 | Insulation resistance after immersing in water | MΩ | ≥5×101 |

Table 3: Electrical strength perpendicular to the layer direction
Thickness mm | Normal value | | Thickness mm | Normal value |
0.5 | ≥8.10 | 1.8 | ≥4.80 |
0.6 | ≥7.70 | 2.0 | ≥4.60 |
0.7 | ≥7.30 | 2.2 | ≥4.40 |

1.0 | ≥6.30 | 2.8 | ≥4.10 |
1.2 | ≥5.80 | 3.0 | ≥4.00 |
1.5 | ≥5.25 | | |
Note: 1. Electric strength perpendicular to layer direction at 90±2ºC oil can optional choose one 20s raising voltage class by class and the requirement of voltage resistance test for 1 min. If the material is conform with one of the both methods, the electric strength shall be considered to be also conform with the standard. 2. If the arithmetic average of the sample thickness is between the both thicknesses listed in the above table, its requirement value shall use the interpolation method to get. If the average is below 0.4mm,the requirement value of electric strength shall use the one of 0.4mm, If the normal thickness is 3mm and the average of the sample thickness is over 3mm,the requirement value of 3mm shall be used. |
Table 4: Water absorption
Mean thickness mm | Max. water absorption mg | | Mean thickness mm | Max. water absorption mg |
0.5 | 127 | 5.0 | 175 |
0.6 | 129 | 6.0 | 182 |
0.8 | 133 | 8.0 | 195 |

2.5 | 157 | 20.0 | 277 |
3.0 | 162 | 25.0 | 311 |
4.0 | 169 | Processed by one side to 22.5 | 373 |
Note: 1. If the arithmetic average of the sample thickness is between the both thicknesses listed in the above table, its requirement value shall use the interpolation method to get. 2. If the average is below 0.4mm, the requirement value of water absorption shall use the one of 0.4mm. If the normal thickness is 25mm and the average of the sample's thickness is over 25mm,the requirement value of 25 mm shall be used. If the thickness of the laminates is 25,it shall be processed to 22.5±0.3mm by one-side frame and the surface shall be smooth. |
