Outdoor cable introduction and use of outdoor wiring

The network cable is divided into an indoor cable and an outdoor cable. In the integrated wiring project, the outdoor cable is a transmission medium that is often used in outdoor wiring.

The characteristics of the outdoor cable is the outer layer of black PE water-blocking leather and the inner layer of PVC waterproof layer. It can well use outdoor bad weather and change the weather. The double-layer line skin is waterproof and sun-protective, while the outer layer of black PE water-blocking skin is better than the indoor network cable. The skin should be thick. Outdoor wiring is difficult in comparison with indoor wiring. Thick skin is conducive to when the wiring, it is not easy to pull the skin, not easily involved in the copper core, played a wear, tensile and compressive effect.

The outdoor wiring also serves as a buried network cable. The embedded wall is more time-consuming, and the buried network cable can easily pull off the outer sheath of the network cable and cause the copper core to break off, resulting in the inability to transmit network data. Due to the relatively thick skin of the outdoor network cable, it is relatively safe when wiring, and it has the characteristics of waterproof outside, which can be applied to the environment with a damp environment.

When choosing an outdoor cable, it is best to choose outdoor oxygen-free copper cable for high transmission requirements and long transmission distance. The outdoor copper cable and the outdoor oxygen-free copper cable are commonly used in the project. The resistance of the copper is much higher than that of the oxygen-free copper material. For the super-five cable, the oxygen-free copper cable resistance is within 30 ohms within 300 meters. Internal 110 ohms or so.

All copper cables generally can only transmit about 80 meters, while oxygen-free copper cables generally can transmit 120 meters to 150 meters, and the resistance is small and the transmission effect is good.

Over-wet or cold environments can choose outdoor cable, while the outdoor environment is changeable, the sun and rain often occur, the outdoor cable can waterproof sunscreen, and better adapt to external weather problems.
