Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0014] Please see Figure 1 In this embodiment of the utility model, a multi-core low-temperature resistant dynamic control cable includes a wrapping layer 4, which is made of PTFE tape. The wrapping layer 4 wraps one pair of core wires 1 and two single core wires 2. The gap between the wrapping layer 4 and the core wires is filled with a filler layer 3, which is made of tensile and corrosion-resistant Kevlar. The outer side of the wrapping layer 4 is wrapped with a shielding layer 5, which is made of tin-plated copper braided structure. The outer side of the shielding layer 5 is wrapped with an outer sheath 6, which is made of TPE sheath. The sheath material is a specially modified elastomer material that is resistant to low temperatures down to -60°C to ensure normal high-speed dynamic operation in an environment of -40°C. The multi-core composite structure meets the complex control signal transmission requirements. The twisted pair and cabling adopt a 100% untwisting process. To ensure the durability and stability of low-temperature dynamic operation, the wrapping tape uses soft PTFE wrapping tape. The shielding layer adopts an ultra-fine tinned copper braided structure. To enhance the cable's tensile strength, the filler reinforcing wire uses Kevlar, which is the most tensile and corrosion-resistant, as the filler material.

[0015] Both the core wire 1 and the single-core wire 2 include a conductor and an insulation layer. The conductor is wrapped with an insulation layer made of fluoroplastic, and the conductor is a Class 6 stranded conductor. The conductor typically uses high-quality, ultra-fine single wires of Class 6 stranded conductor to ensure good conductivity and flexibility. The insulation material is made of corrosion-resistant, low-temperature-resistant, and ultra-high-temperature-resistant fluoroplastic, maintaining stable electrical and mechanical properties in an environment of -40°C.

[0016] The cable exhibits excellent low-temperature resistance, capable of operating normally in frigid conditions down to -40°C without embrittlement or cracking. It meets 10 million dynamic drag chain tests at -40°C and can withstand dynamic stresses generated during low-temperature operation, such as bending, tension, and torsion, ensuring long-term stable signal transmission and guaranteeing precise equipment control and efficient operation.
