Description

technical field [0001] The invention relates to the field of wire and cable processing and manufacturing, in particular to a novel fluorine-insulated wire for automobile engine control and a manufacturing method thereof. Background technique [0002] With the progress of society and the gradual improvement of living standards, the electronic equipment on the car is becoming more and more abundant, and people's requirements for the car environment are getting higher and higher, so that the space left for wiring is getting smaller and smaller. A small space is not conducive to heat dissipation. Therefore, the performance of high temperature resistant wires, especially the wires of the engine and its accessories, is increasingly tested. [0003] Fluorine insulating material is a very stable material with a high temperature resistance range of 150°C to 250°C, which can meet the requirements of automotive engine control wires. However, if the general processing method is used fo...
