[0002] Flexible high temperature resistant cable is a specially designed cable with very flexible performance and the ability to withstand high temperatures. This cable usually uses special insulation and sheath materials to ensure good performance and durability in high temperature environments. The high flexibility design allows this cable to bend and turn in a small space, suitable for complex wiring environments. At the same time, the high temperature resistance allows this cable to maintain stable working performance in high temperature working environments and is not easily affected by temperature.
[0003] Although the wind power cables currently used in the cabin can meet the requirements of flexible and high-temperature resistant electrical connections, most of them achieve flexibility by setting an aluminum alloy core and achieve high-temperature resistance by setting an outer sheath of high-temperature resistant material. The method is single, and once the outer sheath is damaged, the high-temperature resistance effect is poor, and further improvement is needed.
