Abstract

The invention discloses a coating insulation material for the outermost layer of winding wires, which comprises the following raw material components in parts by weight: 60-80 parts of high-temperature nylon, 20-30 parts of polyamide, 0.1-1 part of anti-oxidant agent. The coating insulating material used for the outermost layer of winding wires in the present invention optimizes the formulation of the coating insulating material used for the outermost layer of winding wires, the formula is reasonable, not only has excellent fluidity, but also has good mechanical strength and flexibility, It is extruded on the outer surface of the secondary outer insulating protective layer of the winding wire through an extruder, and can be evenly and seamlessly attached to the outer surface of the secondary outer insulating protective layer. The obtained winding wire not only has a very smooth outer surface, but also has a high temperature resistance Reach class F (155°C).

Description

technical field [0001] The invention relates to the technical field of three-layer insulated winding wires, in particular to a covering insulating material used for the outermost layer of winding wires. Background technique [0002] Three-layer insulated winding wire is a kind of high signal transmission, high withstand voltage, high shielding insulated wire, which is composed of a metal conductor and three kinds of insulation layers wrapped outside the metal conductor. With the continuous expansion of the application field of triple-layer insulated wire, people's requirements for triple-layer insulated wire are also getting higher and higher. Especially in the field of high voltage and high frequency conversion technology, not only the metal conductors are required to have good high signal transmission, high withstand voltage, and high shielding performance, but also the requirements for the adaptability of the working environment of the insulation layer are getting higher ...
