Example Embodiment
[0011] The inorganic insulating powder layer 2 is adhered to the mica-containing side of the mica tape with a silicone adhesive, and the weight of the inorganic insulating powder layer per square meter is 0.1-0.5 g. The material of the inorganic insulating powder layer is silicon or aluminum oxide or calcium carbonate or aluminum hydroxide or glass or magnesium hydroxide, which can be any one of them, or a mixture of two or more of them, and the particle size of the material The diameter is 1nm-100nm. Inorganic insulating powder 4 is also attached to the substrate surface of the mica tape 3. The mica tape is longitudinally wrapped on the conductor 1. The side of the mica with the mica and inorganic insulating powder layer faces inward to contact the conductor 1, and glass is used on the mica tape After the ribbon is tied tightly, squeeze the insulating layer 5 and the outer sheath.
