室外全銅網線和室內全銅網線在導體材質上是一樣的，所以電阻相差不大，傳輸性也就沒有太大區別。0.5全銅300米內的測試的電阻為105-110歐姆左右，傳輸距離一般在80米左右。

室外全銅網線和室內全銅網線的區別主要在結構上。

室外全銅網線有雙層線皮，外層為黑色阻水PE料，內層為PVC料防水皮，雙層線皮主要起到防水、防晒、抗拉、抗壓的作用，能適應外多變的天氣，更好的保護內部導體，提高抗氧化性。

室內全銅網線只有單層線皮，外層線皮為PVC料，具有抗拉作用，但不具備防水防晒作用。線皮柔軟方便穿管以及牆壁布線。要注意拉線時不要太過用力，容易拉壞線芯。

What is the difference between an outdoor copper cable and an indoor copper cable?

The outdoor copper cable and the indoor copper cable are the same in the conductor material, so the resistance is not much different, and the transmission is not much different. The resistance of the test in 0.5 cm of copper is about 105-110 ohms, and the transmission distance is generally about 80 meters.

The difference between the outdoor copper cable and the indoor copper cable is mainly in the structure.

The outdoor copper wire has a double-layer wire, the outer layer is black water-blocking PE material, and the inner layer is PVC material waterproof skin. The double-layer wire skin mainly functions as waterproof, sunscreen, tensile and compressive, and can adapt to many external Changed weather, better protection of internal conductors and improved oxidation resistance.

The indoor copper wire has only a single layer of wire, and the outer layer of skin is made of PVC material, which has a tensile effect, but does not have a waterproof and sunscreen effect. The wire is soft and easy to wear and the wall wiring. Be careful not to use too much force when pulling the wire, it is easy to pull the wire core.
