[0021] Please see Figure 1 The video communication cable provided by this utility model includes a core wire component, a temperature regulating tube 4, and an outer sheath. The core wire component and the temperature regulating tube 4 are both wrapped inside the outer sheath, and the temperature regulating tube 4 is used for the introduction of the medium to regulate the temperature inside the outer sheath.

[0022] It is known that the temperature regulating tube 4 can be a dense spring tube made of high-strength, high-elasticity, ultra-thin rectangular spring steel. It has high strength, good flexibility, and excellent tensile strength. During use, low-temperature or high-temperature gas can be introduced to regulate the overall temperature of the cable, enabling applications in special scenarios such as extremely low and extremely high temperatures. The core wire components are used for the transmission of data signals such as video, and the outer sheath provides insulation and effectively protects the core wire components and the temperature regulating tube.

[0023] Please see Figure 1 In some embodiments, the outer sheath includes a cold-resistant and corrosion-resistant cross-linked silicone rubber sheath layer 5 and a highly flexible and high-strength glass fiber braided outer sheath 6. The core wire component and the temperature regulating tube 4 are wrapped inside the cold-resistant and corrosion-resistant cross-linked silicone rubber sheath layer 5, and the highly flexible and high-strength glass fiber braided outer sheath 6 wraps the cold-resistant and corrosion-resistant cross-linked silicone rubber sheath layer 5.

[0024] It is known that the cold-resistant and corrosion-resistant cross-linked silicone rubber sheath layer 5 has low electromagnetic loss, high tensile strength, and good corrosion resistance and temperature resistance. The maximum applicable temperature range of the cold-resistant and corrosion-resistant cross-linked silicone rubber sheath layer 5 is -120℃ to 350℃, and it is widely used in polar expedition equipment. The highly flexible and high-strength glass fiber woven outer sheath 6 has good flexibility, and the internal working units will not catch fire, ensuring that the equipment has sufficient time to deal with emergencies in the event of a fire.

[0025] Please continue reading. Figure 1 In some embodiments, the core wire component includes a high-frequency data transmission twisted pair 1, a cold-resistant video cable 2, and a cold-resistant environmentally friendly cross-linked silicone rubber control wire core 3, all of which are encased in an outer sheath.

[0026] Understandably, the twisted pair and cabling process used in high-frequency data transmission twisted pair cable 1 employs a matched pitch and a perfect untwisting process. The twisted pair pitch is cleverly designed according to the signal wavelength to avoid electromagnetic resonance effects (e.g., blue / white blue: 7.3mm; orange / white orange: 9.7mm; green / white green: 11.3mm; brown / white brown: 13.7mm). The cabling pitch is 80-85mm, ensuring good information transmission performance in the high-frequency band. Key indicators such as crosstalk, attenuation, and impedance are controlled within the design range. The core wire component of this structure combines multiple core wires, thus effectively meeting different needs.

[0027] Please see Figure 2 In some embodiments, the high-frequency data transmission twisted pair 1 includes a first finely twisted flexible silver-plated copper conductor 101, a high-frequency data transmission twisted pair cold-resistant cross-linked silicone rubber insulation layer 102, and a first self-adhesive aluminum foil wrapping shielding layer 103. The high-frequency data transmission twisted pair cold-resistant cross-linked silicone rubber insulation layer 102 wraps the first finely twisted flexible silver-plated copper conductor 101, and the first self-adhesive aluminum foil wrapping shielding layer 103 wraps the high-frequency data transmission twisted pair cold-resistant cross-linked silicone rubber insulation layer 102.

[0028] Understandably, the first finely stranded soft silver-plated copper conductor 101 (metal plating thickness > 0.03 mm) provides a low-resistance, high-velocity data channel for high-frequency pulse current. The cold-resistant cross-linked silicone rubber insulation layer 102 of the stranded wire has low electromagnetic loss, high tensile strength, good corrosion resistance and temperature resistance, ensuring low attenuation, low impedance and high clarity of ultra-high frequency data current, while ensuring stable capacitance and wave velocity ratio of the product. The first self-adhesive aluminum foil wrapping shielding layer 103 has good structural stability and good shielding effect against mid-to-high frequency pulse interference from 0~1000MHz.

[0029] Please see Figure 3 In some embodiments, the cold-resistant video cable includes a second finely stranded flexible silver-plated copper conductor 201, a cold-resistant high-density polyolefin video cable core insulation layer 202, and a second self-adhesive aluminum foil wrapping shielding layer 203. The cold-resistant high-density polyolefin video cable core insulation layer 202 wraps the second finely stranded flexible silver-plated copper conductor 201, and the second self-adhesive aluminum foil wrapping shielding layer 203 wraps the cold-resistant high-density polyolefin video cable core insulation layer 202.

[0030] It is understandable that the cold-resistant high-density polyolefin video cable core insulation layer 202 has cold resistance and good insulation properties, the performance of the second finely stranded soft silver-plated copper conductor 201 is the same as that of the first finely stranded soft silver-plated copper conductor 101, and the second self-adhesive aluminum foil wrapping shielding layer 203 is the same as that of the first self-adhesive aluminum foil wrapping shielding layer 103.

[0031] Please see Figure 4 In some embodiments, the cold-resistant and environmentally friendly cross-linked silicone rubber control core 3 includes a third finely stranded soft silver-plated copper conductor 301, a cold-resistant control core environmentally friendly cross-linked silicone rubber insulation layer 302, and a third self-adhesive aluminum foil wrapping shielding layer 303. The cold-resistant control core environmentally friendly cross-linked silicone rubber insulation layer 302 wraps the third finely stranded soft silver-plated copper conductor 301, and the third self-adhesive aluminum foil wrapping shielding layer 303 wraps the cold-resistant control core environmentally friendly cross-linked silicone rubber insulation layer 302.

[0032] It is known that the third finely stranded, soft, silver-plated copper conductor 301 of the cold-resistant, environmentally friendly cross-linked silicone rubber control wire core 3 uses 0-2.5mm² wire. 2 Annealed silver-plated copper soft conductors provide power for instruments and equipment in ships and marine engineering for purposes such as lighting and low-power power. They can also be used as control conductors. This part can also be supplemented with communication conductors such as telephone conductors, video conductors, and radio frequency cable conductors for mobile communication as needed.
