Classification and Application of Enamelled Wire

1 Acetal enameled wire: thermal conductive i05 and 120, with good mechanical strength, adhesion, resistance to transformer oil and refrigerant. However, this product has defects such as poor moisture resistance, low thermal softening breakdown temperature, and weak durability of benzene alcohol mixed solvents. Currently, it is only used in a small amount for oil-immersed transformers and oil-filled motor windings.

What is the difference between an inductor coil and an inductor

Inductive coil is an important component within an inductor. Because inductors are generally composed of a skeleton, winding (coil), shielding cover, packaging material, magnetic core or iron core, etc.

What to pay attention to when using and installing inductance coils

The Body relative direction of coil equipment and other components must meet the planning requirements, or the normal operation of the whole machine will be affected. For example, in a simple semiconductor radio, the direction of the high-frequency resistor coil and magnetic antenna should be arranged appropriately. The antenna coil and oscillation coil should be perpendicular to each other to avoid the influence of mutual coupling.

What are the reasons for the blackening of the coil?

What are the reasons for the blackening of the coil?

Copper wire annealing refers to a metal heat treatment in which copper wire is slowly heated to a certain high temperature and maintained for a period of time, then cooled at a corresponding rate. Copper wire annealing can effectively reduce hardness, improve machinability, eliminate residual stress, stabilize size, and reduce deformation and crack tendency; Refine grain size, adjust structure, and eliminate structural defects. However, the manufacturer of Beijing Kexun Hongsheng High Temperature Line believes that once the temperature exceeds 50 ℃ during the production process, the required extraction time is insufficient, the SO2 content is high, and the protective gas is impure, which will cause insufficient annealing. After a period of time, the copper wire will be prone to blackening.
