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 that transmits radios to the outside. This effect will degrade the power of the signal and reduce the received signal strength.

The coaxial cable is designed to solve this problem. The radios emitted by the center wires are isolated by a mesh-like conductive layer, which can control the transmitted radio through grounding.

There is also a problem with coaxial cables. If the cable is crushed or twisted in a certain segment, the distance between the center wire and the meshed conductive layer is not consistent. This will cause internal radio waves to be intercepted. Reflected back to the signal source. This effect reduces the signal power that can be received. To overcome this problem, a layer of plastic insulator was added between the center wire and the mesh conductive layer to ensure that the distance between them was always consistent. This also causes the cable to be stiff and not bendable.

main application range

The main application areas are: bracket connection of equipment, closed-circuit television (CCTV), shared antenna system (MATV) and the transmission of color or monochrome RF monitors. These applications do not require the selection of precision video coaxial cables with particularly strict electrical tolerances. The characteristic resistance of the video coaxial cable is 75 ohms. This value is not optional. Physics has demonstrated that the attenuation characteristic optimized for video signals occurs at 77 ohms. In low-power applications, materials and design determine the cable's optimal impedance to be 75 ohms.

Standard video coaxial cables both have solid and multi-strand conductor designs. It is recommended to use a multi-strand conductor design in some applications where the cable is to be bent, such as the internal connection of a CCTV camera to the tray and bracket assembly, or the transmission cable of a remote camera. There is also monitoring equipment.The scope of application: Mainly applicable to transmission equipment and various types of digital program-controlled switches, signal transmission between optical transmission equipment internal connection and distribution frame, used to transmit data, audio, video and other communication equipment. The sheath is made of flame-retardant material and has a high safety factor. The use of advanced technology to produce a good cable impedance uniformity. Multi-core cables are more convenient in rack installation. Coaxial cable is mainly applied to office buildings and multi-functional development community applications. Its advantages include reducing repetitive wiring and reducing the total investment cost of the project.
