Embodiment 1
[0032] Example 1, combined with figure 1 , Parameter performance comparison table, process parameter table for description.
[0033] A high temperature and high voltage wire for aviation, refer to the performance parameter comparison table, process table and attached figure 1 The specific instructions are as follows:
[0034] It includes a 25% nickel-copper alloy-plated stranded conductor 1, and the 25% nickel-copper alloy-plated stranded conductor 1 is wrapped with a high-temperature and fire-resistant inner insulating layer 2;
[0035] The inner insulating layer 2 is cross-wrapped with three materials including polyperfluoroethylene propylene, polyimide, and polytetrafluoroethylene as the outer insulating layer 3.
[0036] Further, the inner insulating layer 2 is a double-sided synthetic mica tape with a thickness of 1.0 mm; the outer insulating layer and the inner insulating layer are formed by high-temperature sintering. The mica tape is synthesized from mineral mica, magnesium ...
