Embodiment 1
[0038] This embodiment provides a motor lead cable, such as figure 1 As shown, the motor lead cable includes a conductor 1 (the fifth type of conductor), a conductor covering layer 2 (polyester tape, with a thickness of 0.05mm), and a flame-retardant silicone rubber insulating layer 3 (thickness of 3.0 mm) from the inside to the outside. mm) and fiber braided coating layer 4 (glass fiber braided layer and silicone resin, the weaving density of the glass fiber braided layer is 95%, and the thickness of the silicone resin is 0.1 mm).
[0039] The preparation method of the above motor lead cable comprises the following steps:
[0040] (1) Twist the conductor monofilament bundles into strands, and then normal strand the strands in the opposite way layer by layer;
[0041] (2) Overlapping and winding the conductor cladding layer of 0.05mm on the conductor surface obtained in step (1);
[0042] (3) Extrude and coat a 3.0mm flame-retardant silicone rubber insulation layer on the su...
