在綜合布線系統中,雖然仍有人使用鐵鋁網線,但由於鐵鋁網線壽命較短,而且氧化速度快,因此也逐漸被市場淘汰。那麼,如何分辨鐵鋁網線和銅包鐵網線?
分辨鐵鋁網線和銅包鐵網線的方法
1、最簡單的方法就是用磁鐵,磁鐵和鐵是相互吸引的關係,如果網線是含有鐵的成分,馬上就能測試出來。
2、軟硬度,銅包銀網線內部4對線芯的軟硬度都是一樣的;而鐵鋁網線則是含鐵的2對是比較硬的,另外2對銅包鋁線芯相對是比較軟。
3、用火烤,鐵質和銅質的網線遇火不會很快軟化,但鋁質一遇火就會軟化得比較快。

Method for distinguishing iron-aluminum wire and copper-clad wire
1. The simplest method is to use a magnet. Magnets and iron are attracted to each other. If the cable is a component containing iron, it can be tested immediately.
2. The hardness of the four pairs of cores inside the copper-clad silver cable is the same; the two pairs of iron-aluminum cables are relatively hard, and the two pairs of copper-clad aluminum cores are relatively soft.
3, With fire, iron and copper mesh will not soften quickly in the event of fire, but the aluminum will be softened faster in case of fire.
