電纜主要有銅導體：
The cable mainly has copper conductor
導體可分為裸銅，鍍銅，銅包鋼，銅合金，銅箔絲等。
Conductor can be divided into bare copper, copper plating, copper clad steel, copper alloy, copper foil wire, etc.
裸銅---導體電阻小，易氧化 鍍銅---抗氧化性增強
Bare copper --- conductor resistance is small, easy to oxidize copper plating --- oxidation resistance is enhanced
鍍錫銅---抗氧化性增強，便于后續焊接 鍍銀銅---導電性強，價格高，多用于射頻電纜及氟塑料型線  流水槽模具 景觀石 檢查井鋼模具 保定通風管道 隔離墩模具 保定保潔公司高溫線
Tinned copper - oxidation resistance enhanced, easy to follow-up welding silver plated copper - strong conductivity, high price, mostly used for radio frequency cable and fluoroplastic high temperature wire
銅包鋼---強度高，常用于架空電纜
Copper clad steel - high strength, commonly used in overhead cables
銅合金---強度高（銅中加入少量型槽模具 一次性止血帶 保定水處理設備 一次性止血帶 保定空壓機 北京真空泵其它金屬）
Copper alloy - high strength (copper with a small amount of other metals)
銅箔絲---抗彎折能力強，柔軟度高（將銅壓成薄片后包裹在彈性纖維上）
Copper foil wire: strong bending resistance and high softness (copper is pressed into thin sheets and wrapped on elastic fiber)
為提高導體強度，通常采取將多條銅 線絞合的方式
In order to improve the strength of the conductor, the method of twisting several copper wires is usually adopted
二、電纜絕緣體：
2、 Cable insulator:
常用絕緣材質有PVC（PolyVinyl Chloride ，聚氯乙烯)、SR-PVC（Semi-rigid PVC，半硬質PVC）、PP (Polypropylene，聚丙蠕動泵 保定建筑設計 保定網站建設 保定網站制作 保定網絡公司 保定辦公家具 保定輕鋼別墅 烯）、PE（Polyethylene，聚乙烯）、Foam-PE、Foam-PE+Skin等，還有最新的氧化鎂（MI）礦物絕緣體。
The commonly used insulation materials are PVC (polyvinyl chloride), sr-pvc (semi-rigid PVC), PP (polypropylene), PE (polyethylene), Foam PE, Foam PE + skin, etc., as well as the latest magnesium oxide (M
