[0016] Reference Figure 1-2A high-conductivity carbon fiber cable for medical electromagnetic interference protection includes a conductor 1, an insulation layer 2 on the outside of the conductor 1, a fiber braided layer 3 wrapped around the outside of the insulation layer 2, and an organosilicon conductive coating layer 4 on the outside of the fiber braided layer 3. The organosilicon conductive coating layer 4 and the fiber braided layer 3 form an armor-like outer shell, which better protects the stability of the internal structure of the product, prevents the effects of stress concentration during bending, and also has good anti-static and static dissipation effects. It also effectively shields against electromagnetic interference, is resistant to chemical corrosion, and increases the flexibility and mechanical strength of the cable, thereby increasing the service life and corrosion resistance of the wire. An outer sheath 5 is wrapped around the outside of the organosilicon conductive coating layer 4. The conductor 1 includes high-conductivity carbon fiber 6, a central tensile fiber 7, and aramid fiber 8.

It bears the main force in the entire conductor 1 structure and can ensure the stability of the structure, significantly improving the overall tensile performance of the conductor.

[0017] The insulation layer 2 is made of polypropylene, which has the advantages of impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion.

[0018] The fiber braided layer 3 is made of aramid fiber with high tensile strength, high wear resistance and high toughness through special process. It increases tensile strength, ensures the stability of the internal stress of the entire product, further increases the tightness of the cable structure, prevents bulging and loosening during torsion, improves the overall tensile and torsional performance of the cable, and increases the flexibility and mechanical strength of the cable, as well as the service life and corrosion resistance of the wire.

[0019] The outer sheath is made of soft, antibacterial polyurethane elastomer material, which is resistant to ozone, aging, abrasion, corona, UV radiation, arc, high and low temperatures, tensile strength, and flexural strength. It has good shrinkage and excellent antibacterial properties; good elasticity and resistance to compression deformation; and good oil and solvent resistance. It can withstand 30-40kV voltage, meets UL94 V0 flame retardant requirements, RoHS 10 requirements, and REACH environmental performance testing. It can be used in both high and low temperatures, improving reliability and extending service life, and is environmentally friendly and pollution-free during use.
