电线电缆的制造与大多数机电产品的生产方式是完全不同的。机电产品通常采用将另件装配成部件、多个部件再装配成单台产品，产品以台数或件数计量。电线电缆是以长度为基本计量单位。所有电线电缆都是从导体加工开始，在导体的外围一层一层地加上绝缘、屏蔽、成缆、护层等而制成电线电缆产品。产品结构越复杂，叠加的层次就越多。
Wire and cable manufacturing is totally different from most mechanical and electrical products. Mechanical and electrical products usually adopt the method of assembling another part into parts, and then assembling multiple parts into a single product. The product is measured by the number of units or pieces. Wires and cables are measured in length. All wires and cables are manufactured from the processing of conductors by adding insulation, shielding, cabling and protective layers to the outer layers of conductors. The more complex the product structure is, the more layers it overlaps.
