Nuclear power supply
1. Scope of application
· This product is suitable for control and signal connection cables used in nuclear power plant rated voltage Uo / U of 0.6 / 1kV control system network.
· The long-term working temperature of the cable conductor is 90 ℃. The maximum temperature of the cable conductor during short-circuit does not exceed 250 ℃, and the duration does not exceed 5 seconds.
· The ambient temperature when laying the cable should not be lower than 0 ℃.
· The allowable bending radius when laying the cable is:
— Unarmored cables, not less than 6 times the cable diameter;
— Cables with armored or copper tape shielding results should not be less than 12 times the cable diameter;
— Flexible cables with shielded structure should not be less than 6 times the cable diameter.
When the long-term allowable working temperature of the conductor is not more than 90 ° C, the identification life of the cable is not less than 40 years.
· The finished cable should meet the requirements of Class A bundled combustion test specified in the GB / T18380.3 standard.
· Finished cable smoke density: light transmittance is not less than 70%.
· Radiation resistance: 25 × 104Gy
· Halogen-free: When non-metallic materials are burned, the acidity (expressed as PH value) of the escaping gas should be greater than 4.3; the conductivity should not be greater than 10 μS / mm.
