一般介绍 General introduction

漆包线主要由导体和绝缘层两部组成，裸导体线经退火软化后，再经过多次涂漆，烘焙而形成绝缘厚度相对很薄，耐压相对很高的各类绕组产品。近些年来，随着电子电器类产品的飞速发展，漆包线已应用到生产生活的各个领域，如各类电机、变压器、整流器、音圈、电磁电感线圈等。

Enameled wire is mainly composed of conductor and insulation layer. The main production process includes annealing the conductor and enameling several time on the surface to get relatively thin insulation but high break-down voltage. In recent years, with the rapid development of electrical and electronic products, enameled wire has been applied to various fields of production and life, such as various types of motors, transformers, rectifiers, voice coil, electromagnetic inductance coil.

漆包线的分类Classification of enamel wire

按导体材质分类Classification by conductor

A 纯铜漆包线enameled copper wire

优点：作为传统种类的漆包线，应用领域广泛，焊接方便，性能稳定优异。

缺点：生产成本高。

Advantages: as the most traditional type of enameled wire, the application field is wide, soldering convenient, performance stable.

Disadvantages: high cost of production.

B 铜包铝漆包线

优点：作为纯铜漆包线的替代品，由于具备优异的高频传输性能，开始应用于各类高频电磁电感线圈中；现为了节省生产成本，已广泛应用于各类电子线圈，变压器，电感，整流器，各类大小型电机方面，并且具有优异的锡焊性能。其密度小，单位产品重量较铜线至少节省40%，可以大幅节省生产材料成本。

缺点：抗拉强度约为铜线的50%，实际生产时，较纯铜线易断线。

B Enameled copper clad aluminum wire

Advantages: as envelope alternatives of pure enameled copper wire, it has good performance of high frequency transmission, originally it was applied in various types of high-frequency electromagnetic induction coil; now in order to save more production cost, ECCA wire has been widely used in various types of electronic coils, transformers, inductors, rectifiers, and all kinds of large and small motors, and has excellent soldering performance. Its density is low, the weight of the unit product can at least save 40% of the copper wire, it can save a lot of cost of production material. Disadvantages: the tensile strength is about 50% of pure copper wire, Ecca wire will break more frequently than copper wire.

C 铝漆包线 Enameled aluminium wire

优点：由于比铜包铝更低的密度，单位产品重量较铜线至少节省60%，可以更大幅度节省生产材料成本。

Advantages: due to much lower density than copper clad aluminum wire, weight per unit product can save at least 60% than the copper wire. Using aluminium wire will save much more cost of production materials.

缺点：抗拉强度约为铜线的30%-40%，生产时，导体易拉伸；同时由于铝导体表面不易直接焊锡，故焊接点需处理。

Disadvantages: tensile strength is about 30%-40% of the copper wire, the conductor is easy to stretch during production; 

The surface of the aluminum conductor is not easy to direct solder, special treatment of welding joints is required.
