鐵鋁網線指的是四鐵四鋁網線，也就是網線內部的4對線芯，有2對是銅包鋁材質，有2對銅包鐵材質，這類線材是網線中最普通的，只能用在普通的工程中，一般傳輸60-70米左右。

銅包銀網線指的是內部導體材質為進口鋁，外鍍一層飽滿的無氧銅層，由於銅包銀網線的電阻比較小，在正常環境下，可以傳輸180米左右。但銅包銀網線的抗氧化性較差，一般使用壽命在2-3年左右，所以選擇銅包銀網線要注意工程的使用時間問題。

如何辨別鐵鋁網線和銅包銀網線?

①鐵鋁網線內部含有鐵質，可用磁鐵辨別，若相互吸引就能斷定是鐵鋁網線。

②火燒，由於鐵的硬度較高，不容易燒斷，所以鐵鋁網線是很容易判斷出來的。銅包銀網線則4對線芯的硬度都是一樣的，且都容易被火燒軟。

What is the difference between iron-aluminum wire and copper-clad silver wire?

The iron-aluminum cable refers to the four-iron four-aluminum cable, that is, the four pairs of cores inside the cable. Two pairs are made of copper-clad aluminum and have two pairs of copper-clad iron. This type of wire is the most common in the cable. Can be used in ordinary engineering, generally transmitting about 60-70 meters.

The copper-clad silver wire refers to the inner conductor material is imported aluminum, and the outer layer is coated with a full layer of oxygen-free copper. Because the resistance of the copper-clad silver wire is relatively small, it can be transmitted in a normal environment for about 180 meters. However, the copper-coated silver mesh wire has poor oxidation resistance, and the general service life is about 2-3 years. Therefore, it is necessary to pay attention to the use time of the project when selecting the copper-clad silver mesh cable.

How to distinguish iron-aluminum cable and copper-clad silver cable?

1 The iron-aluminum wire contains iron inside, which can be distinguished by magnets. If it attracts each other, it can be concluded that it is an iron-aluminum wire.

2 Fire, because the hardness of iron is high, it is not easy to blow, so the iron-aluminum wire is easy to judge. The copper-clad silver mesh cable has the same hardness for the four pairs of cores, and is easily burnt soft.
