4000098-516 线缆定义1:由-根或多根相互绝缘的导体和外包绝缘保护层制成，将电力或信息从-处传输到另-处的导线。
定义2:通常是由几根或几组导线(每组至少两根)绞合而成的类似绳索的电缆，每组导线之间相互绝缘,并常围绕着一根中心扭成， 整个外面包有高度绝缘的覆盖层。电缆具有内通电，外绝缘的特征。
分类
电缆有电力电缆、控制电缆、补偿电缆、屏蔽电缆、高温电缆、 计算机电缆、信号电缆、同轴电缆、耐火电缆、船用电缆、矿用电缆、铝合金电缆等等。它们都是由单股或多股导线和绝缘层组成，用来连接电路、电器等。电缆按照光伏电站的系统可分为直流电缆及交流电缆
Definition 1: A wire made of one or more mutually insulated conductors and an external insulation protective layer that transmits power or information from one location to another.
Definition 2: It is usually a rope like cable composed of several or several sets of wires (at least two in each group) twisted together, with each set of wires insulated from each other and often twisted around a center, with a highly insulated covering layer on the entire outer surface. Cables have the characteristics of internal electrification and external insulation.
classification
Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are all composed of single or multiple wires and insulation layers, used to connect circuits, electrical appliances, etc. Cables can be divided into DC cables and AC cables according to the system of photovoltaic power plants
