SYV-75-5 is a "closed-circuit cable, also known as a Coaxial Cable," and a set of "coaxial cable" ratings for a weak-intelligent book. The Video Cable refers to the cable that transmits the video signal (VIDEO) and can be used as the signal transmission of the monitoring system. General Model: SYV75-X (X means its insulation outer diameter 3mm/5mm, the larger the number, the thicker the wire diameter) SYV S - coaxial RF cable, Y - polyethylene, V - polychlorinated Ethylene. 75 means characteristic impedance. Video line 75-3 (100 meters) Normal working transmission distance 75-5 (300 meters) normal working transmission distance 75-7 (500-800 meters) normal working transmission distance, 75-9 (1000-1500 meters) normal working transmission distance. The common model is SYV75-5.
Coaxial Cable Introduction
1.The coaxial cable can be divided into baseband coaxial cable and broadband coaxial cable (ie, network coaxial cable and video coaxial cable) from the purpose of use. Coaxial cable is divided into 50Ω baseband cable and 75Ω broadband cable. The baseband cable is subdivided into thin coaxial cable and coarse coaxial cable. The baseband cable is only used for digital transmission and the data rate can reach 10Mbps.
2.The coaxial cable refers to a cable that has two concentric conductors, and the conductor and the shield share the same axis. The most common coaxial cable is composed of insulated copper wire conductors. On the outside of the inner insulation material is another layer of the ring conductor and its insulator. The entire cable is then sheathed with a PVC or Teflon sheath.
Working theory of the coaxial cable:
The coaxial cable is divided into four layers from the inside to the outside: the center copper wire (single stranded solid wire or stranded wires), the plastic insulator, the mesh conductive layer and the wire sheath. The center copper wire and the mesh conductive layer form a current loop. Since the center copper wire and mesh conductive layer is named for the coaxial relationship.
The coaxial cable conducts alternating current instead of direct current, which means that the current direction will be reversed several times per second.
If a general wire is used to transmit high-frequency currents, this wire is equivalent to an antenna
