Problems solved by technology
However, due to the product heat resistance level, softening breakdown performance, thermal adhesion performance, paint film continuity, etc., it cannot meet the requirements of special electrical products, and the bundled wire itself heats up quickly and other shortcomings.
As a result, the deflection coils of some digital TV color display tubes and high-definition computer monitors have short service life, and some of them burst and hurt people, which not only causes troubles for electronic and electrical enterprises, but also poses a certain threat to personal safety.

Embodiment Construction
[0008] A new type of low temperature resistant enamelled copper round wire, the cross section of the copper round wire is uniform cylindrical, the central cylinder is a copper conductor 1, and the outside of the copper conductor 1 is a 200-grade direct-solderable polyesterimide paint layer 2. The outside of the 200 grade direct solderable polyesterimide paint layer 2 is a low temperature resistant self-adhesive paint layer 3.

The invention relates to a novel low temperature resistant enameled round copper wire. The cross section of the round copper wire is in the shape of a uniform cylinder, the central cylinder is a copper conductor, a 200-level flash-soldering polyesterimide paint layer is arranged outside the copper conductor, and a low temperature resistant self-adhesion paint layer is arranged outside the 200-level flash-soldering polyesterimide paint layer. The enameled round copper wire is resistant to low temperature, high in cut-through performance, good in heat bonding performance, good in paint film continuity, resistant to refrigeration property and preferable in solvent resistance, the self-heating of the conductor is reduced, and the enameled round copper is usually used for refrigeration motors.
Description
technical field [0001] The invention relates to an electrical product, in particular to a novel low-temperature resistant enamelled round copper wire. Background technique [0002] At present, the known 180-grade direct-solderable polyesterimide enameled round copper wire structure is formed by coating a copper conductor and direct-solderable polyesterimide paint, and it is mainly used in the electronics, electrical, and home appliance industries. However, due to the product's heat resistance level, softening breakdown performance, thermal adhesion performance, paint film continuity, etc., it cannot meet the requirements of special electrical products, and the stranded wire itself has shortcomings such as rapid heating. As a result, the deflection coils of some digital TV color display tubes and high-definition computer monitors have short service life, and individual phenomena such as bursting and hurting people occur, which not only causes troubles for electronic and elect...
