弱電布線施工是智能家居組建的基礎,因此注重弱電線纜的質量,才能讓布線系統更加順暢穩定。

如何辨別弱電線纜的質量?

1.護套:表面能看出壓緊裏面編網有規律的「不平度」,且不會產生相對滑動,說明線纜的加工工藝好。

2.檢查屏蔽層編網:編數緊密、分佈均勻,且與絕緣層包裹緊湊,可焊性高,鍍錫銅線刮開後看得出裏面是銅線,說明是好線纜。

3.檢查芯線與絕緣層的粘合力:斜向切開絕緣層,按剝離方向拉開芯線,如果芯線和絕緣層粘合工藝材料,說明是好線纜。

4.縱向抗拉實驗:分開剝開芯線,兩隻手分別握電線相鄰兩層,向相反方向拉動,好電線一般力量是拉不動的。

How to identify the quality of weak current cables?

1. Sheath: The surface can be seen to press the inside of the net to have a regular "unevenness", and will not produce relative sliding, indicating that the cable processing technology is good.

2. Check the shielding layer network: the number is tight, the distribution is even, and the insulation layer is compact and the solderability is high. After the tinned copper wire is scraped open, it can be seen that the copper wire is inside, indicating that it is a good cable.

3. Check the adhesion between the core wire and the insulating layer: cut the insulating layer obliquely and pull the core wire in the peeling direction. If the core wire and the insulating layer are bonded to the process material, it is a good cable.

4. Longitudinal tensile test: separate the core wire separately, and the two hands respectively hold the two adjacent layers of the wire and pull in the opposite direction. The general strength of the wire is not pulled.
