Background

The comprehensive data transmission cable existing in the current market is formed by jointly twisting a plurality of insulated single wires, is single in purpose, cannot be used under various complex environmental conditions, is poor in use performance under high-temperature conditions, and is unstable in data transmission. For example, common high-temperature-resistant cables in the market are mostly made of polyethylene and flame-retardant polyvinyl chloride, and materials can be melted and decomposed under the environment condition of 200 ℃ in a short time. When the cable is used under the condition of high temperature for a long time, redundant substances or material decomposition, wire cores or shielding oxidation easily occur in the cable, the reliability is reduced, and potential safety hazards are caused. For example, in the high temperature resistant cables on the market, glass fibers are commonly used for weaving the sheath, under a high temperature condition or in a vibration space range, the glass fiber material is easily decomposed to generate surplus objects, and the surplus objects are easily attached to key equipment under the high temperature condition to cause potential safety hazards. The cable is not provided with a heat insulation flame-retardant layer, the cable insulation and the sheath are not high temperature resistant and flame retardant, and when the environment temperature is too high or the cable insulation and the sheath are burnt, the cable insulation and the sheath can be softened and even melt and burn; when high-frequency transmission of signals is needed, the attenuation is large, normal transmission of information cannot be guaranteed, the transmission performance is influenced, and the high-frequency transmission cable does not have the characteristics of strong flame retardance, high and low temperature resistance, wear resistance, stretching resistance and the like. For common cables in the market, the middle of the cable is not provided with a reinforcing layer, so that the cable core is easy to break when being pulled, and the condition of no power is caused; the cable is free of a heat insulation layer, so that heat of the external environment is easily conducted to the inside of the cable, the temperature inside the cable is too high, and the transmission performance is influenced; circular copper or silver-plated circular copper wire weaving is adopted, and due to the defects of circular wire shielding, the shielding effect is poor, and the weight is relatively large.
