305m 1000Kbps Transmission Speed Coaxial Cable

I. Product Description:

> This coaxial cable  complies  with the national standard GB/T14864-1993, the United States military standard MIL-C-17G Japanese Industrial Standard JISC3501-1993, the corresponding specifications of the cable can be used instead of in the CCTV system.

> The conductor is made of oxygen-free copper (OFC); the insulation is made of solid core or foamed LDPE; the high-speed weaving machine is shielded, and each batch of wire is sampled and passed through a high-frequency network analyzer.

> The product is used in the closed circuit monitoring system (CCTV) to connect the camera with the monitoring equipment or monitoring equipment interconnection, transmission of video surveillance signals.

The Cable Connection

> Connect 9.5mm plugs, RCA, BNC, TNC, and F-type plugs at both ends of the cable. Connect the cable to a 9.5mm plug as an example: Connect the center conductor of the cable to the center pin connector of the plug, and shield and plug the cable. Shell connection.

Identification:

> Inner Conductor: The diameter meets the standard requirements. Non-standard lines are generally produced with non-standard copper. For example, the use of conductors smaller than the standard can be used for production. This results in direct cable attenuation that is too large and the impedance does not match the system. To the use of length requirements.

> The frequency of domestic CCTV system usage is generally below 10 MHz, using the corresponding cable length

Insulation: The current CCTV cable uses LDPE (low density polyethylene plastic) solid core or foam extrusion insulation. The solid core has good transparency and softness, and the foamed insulation has better softness. However, in the market, the recycled PE material is used as the insulation layer of the video coaxial line, and the color is not pure, which affects the electrical performance of the cable.

Shielding: It is composed of vertical aluminum foil and braided conductor or directly woven. It adopts high-speed braided shield, which is compact and consistent, and ensures the stability of the cable structure. The looseness of the non-standard cable weaving structure will cause the structure to be unstable, and the return loss will be deteriorated during use, which will affect the system performance.

Sheath: The use of the middle jacket to protect the inner core, so it requires a certain mechanical physical strength, non-standard cables generally use recycled materials as the sheath material, poor performance, some with a tear to break, will Hidden risks to installation and use.
