At an accelerated aging temperature of 150°C, a heat aging time standard of 1100 to 1300 hours can be achieved. 2. Products and specifications meet standards Complying with the 4th generation nuclear power plants, it has a durability of more than 60 years at an operating temperature of 90°C. Radiation resistant, with high activation energy between 2.0 and 2.8 eV. Gamma radiation resistance: 850KGy can be used for a long time. Complies with safety standards for nuclear power plants, LOCA (Loss of Coolant Accident) testing. Comply with Design Basis Event (DBE) testing for nuclear power plants. 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 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. The multi-core cable combustion test passed the Class A combustion test in the IEC60332.3 standard.
