C) through optimizing the arrangement of the cable cores, the cable cores are kept round under the condition of not increasing filling, the cable cores with round outer diameters are prevented from being increased, the sheath is convenient to extrude, and the minimum thickness is ensured without increasing the nominal thickness of the sheath.

2. The service temperature of the cable depends on the service temperature of the main materials, and mainly comprises conductors, insulation and jackets. The conductor adopts tinned copper wire, the highest working temperature is 200 ℃, the insulation adopts F46 material, and the conductor can normally work within the temperature range of-65 ℃ to 200 ℃; the sheath adopts TPR elastomer, and the working temperature is-60-125 ℃.

3. The cable structure selects proper conductor specifications according to the power and signal transmission requirements of the whole equipment, designs proper insulation thickness to ensure the impedance and attenuation requirements under specific frequency, and sets the cable structure at the corresponding position of the cable core according to the specific equipment connector point to meet the use requirements.
