3. Test conditions

• Use the Arrhenius model to determine the accelerated aging (deterioration) temperature and time according to IEEE standards.
• According to Thermogravimetric Analysis (TGA) or elongation retention;
•     Elongation Retention calculates the activation energy of the insulation coating material.

Application

Single-core wires or multi-core cables are used in nuclear power plants.

1. Advantages

• The activation energy of PEEK insulator is between 2.0 and 2.8 eV, which is better than traditional EPR, CR, and CSP insulating materials.
• The elongation of PEEK insulation is between 150%~200%.
• Due to its high activation energy, PEEK insulators provide long-term durability of more than 60 years at the normal operating temperature of 90°C in nuclear power plants.
• When exposed to a total integrated dose of 300Mrad of gamma radiation, the insulation will not crack when bent, and it is radiation resistant and crack resistant. It can withstand 850KGy of gamma radiation and can be used for a long time.
• Conforms to the 2.5 kV/5min underwater withstand voltage test.
• The multi-core cable combustion test passed the Class A combustion test in the IEC60332.3 standard.
