漆包線Enameled wire

一般介紹 General introduction
漆包線主要由導體和絕緣層兩部組成，裸導體線經退火軟化后，再經過多次涂漆，烘焙而形成絕緣厚度相對很薄，耐壓相對很高的各類繞組產品。近些年來，隨著電子電器類產品的飛速發展，漆包線已應用到生產生活的各個領域，如各類電機、變壓器、整流器、音圈、電磁電感線圈等。

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.

漆包線的分類Classification of enamel wire

按導體材質分類Classification by conductor

A 純銅漆包線enameled copper wire

優點：作為傳統種類的漆包線，應用領域廣泛，焊接方便，性能穩定優異。

缺點：生產成本高。
Advantages: as the most traditional type of enameled wire, the application field is wide, soldering convenient, performance stable.
Disadvantages: high cost of production.

B 銅包鋁漆包線

優點：作為純銅漆包線的替代品，由于具備優異的高頻傳輸性能，開始應用于各類高頻電磁電感線圈中；現為了節省生產成本，已廣泛應用于各類電子線圈，變壓器，電感，整流器，各類大小型電機方面，并且具有優異的錫焊性能。其密度小，單位產品重量較銅線至少節省40%，可以大幅節省生產材料成本。

缺點：抗拉強度約為銅線的50%，實際生產時，較純銅線易斷線。
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 鋁漆包線 Enameled aluminium wire

優點：由于比銅包鋁更低的密度，單位產品重量較銅線至少節省60%，可以更大幅度節省生產材料成本。

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.

缺點：抗拉強度約為銅線的30%-40%，生產時，導體易拉伸；同時由于鋁導體表面不易直接焊錫，故焊接點需特殊處理。
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.
