Detailed Description
The following is a more detailed description of the present invention with reference to specific embodiments.
The embodiment is as follows: as shown in figure 1, the high-temperature-resistant bending-resistant flexible cable comprises six wire cores 1, wherein each wire core 1 is formed by stranding a plurality of strands of anaerobic copper wires. The insulating layer 2 is wrapped outside each wire core 1, the insulating layer 2 is a silicon rubber insulating layer 2, the bonding energy of silicon-oxygen bonds of the silicon rubber is high, so the cable has high thermal stability, the long-term use temperature range can reach 180-250 ℃, the good thermal conductivity of the cable can improve the current carrying capacity of the cable, the electrical insulation performance of the silicon rubber material is still stable even when the temperature and the frequency change are high or the cable is affected by tide, the silicon dioxide generated after combustion is still an insulator, and simultaneously has high resistivity, the insulation resistance value of the cable can be kept stable in a wide temperature and frequency range, the cable has good resistance to high-voltage corona discharge and arc discharge, and the silicon rubber material has the characteristic of softness, so the cable product has excellent electrical performance, and the installation is simple and convenient. The insulating layer 2 is sleeved with a flame-retardant layer 3 formed by winding halogen-free low-smoke flame-retardant glass cloth, flame-retardant coatings are arranged on the inner side and the outer side of the flame-retardant layer 3, and the flame-retardant coatings can further increase the flame-retardant effect of the flame-retardant layer 3. The outer sleeve of the flame-retardant layer 3 is provided with a sheath layer 4, the sheath layer 4 is made of flame-retardant silicone rubber materials, a connecting rod 5 penetrates through the sheath layer 4, and the connecting rod 5 is located at the circle center of the sheath layer 4 and abuts against all the insulating layers 2. The connecting rod 5 is made of foam silicon rubber, and the foam silicon rubber has high thermal stability and good heat insulation, moisture resistance and shock resistance, so that supporting force can be provided for the wire core 1 around the connecting rod 5, and the cable can be prevented from being bent when the cable is influenced by external force.
