Coaxial cable is an electrical cable composed of a conductive core wrapped with a non-conductive dielectric layer, around the cable core with a metal layer, the outermost has an insulating sheath. British mathematician and engineer Oliver Heaviside invented this coaxial cable, patented in 1880. Since then, coax cable has been popularized in the fields of security, television and the Internet.
– The center conductor is made of solid copper or has many small fibers connected to form a single fiber
– The conductor on the outside of the conductor of the center core is made up of a metal mesh to help prevent electromagnetic interference to center core
– Insulation layer located in between the two types of conductor above to isolate these two layers.
- On the outside is a PVC coating to avoid the effects of the environment
Coax cable is the most common transmission line for radio signals. At present, we can see that coax cable is still used a lot in making television cables. Coaxial cable is also the transmission medium between radio transceivers and antennas, and also transmits computer network connections.
With the outstanding advantages of coax cable, it is now widely used in the market in many different fields. Especially in the application of cable television technology, coax cable plays an extremely important role. At the same time, coax cable is also widely used in communication networks, CCTV systems, CCTV systems, commercial broadcasting. Coax cable is also suitable for use in analog technology and digital technology.
Coax Cable RG-59
It is the thinnest cable, low cost, with the lowest anti-interference ability. RG-59 cables usually cover short distances of less than 150m. Widely used in households, civil works and low-cost camera installation.
RG-6 . Coax Cable
This is a cable with sufficient thickness, anti-interference ability and good resistance to harsh environments. Type RG 59 cable is used for many purposes such as outdoor, ceiling or indoor. This type of wire is quite expensive. RG 59 is mainly used for office buildings, buildings, buildings, projects. The maximum distance of RG-59 is 300-400m.
RG-11 . Coax Cable
RG 11 is an expensive cable, this coaxial cable has high resistance to interference and resistance to external forces. RG 11 is specialized for outdoor installation, wall-mounting, ceiling-mounting for high-value projects. This cable has a very long service life. The maximum distance for RG 11 is 500-600m.
Depending on different needs, we classify coaxial cable with criteria such as:
+ Thin cable: A cable with a diameter of about 0.25 inches. This type of cable is light, flexible and tough, low cost and very easy to install. This cable has the best signal transmission over a distance of 185m.
Thick Cable: This type of cable is twice as large in diameter as the thin cable with a diameter of up to about 0.5 inches. The cable is thick and hard, difficult to construct, but in return, the signal transmission ability is very long, up to 500m.
+ Shielded coaxial cable: this is a metal-sheathed cable that increases anti-interference ability. The characteristics of this shielded coaxial cable are: capable of long-distance transmission with about 500 Mbps in theory, while in practice, coaxial cable is capable of transmitting about 155Mbps with a total length of about 100m with The most commonly seen common speed is around 16Mbps. Because the coax cable has anti-interference shield, it requires experience in the installation process to get the best setup.
+ Coaxial cable without sheath: This type of coaxial cable is used a lot in constructions or locations that are not affected by electric fields due to its anti-interference feature. This type of cable has a lower cost than the same type of shielded cable.
Besides, coaxial cables are also classified with other criteria such as: moisture-proof oil layer with or without, camera system with coaxial cables, etc.
Understanding the pros and cons of coax cable will help us grasp and choose the best coax cable and best suited to our needs. In addition, this also affects how to choose the appropriate analog camera system.
Long distance signal transmission ensures very good video, audio and image signal quality.
– Wires can be combined with electric wires with magnetic fields and metal materials. For example: Fire protection water pipes, electrical troughs…
– The design of coaxial cable has multiple anti-interference layers that add thickness and cost.
Besides, coax cable will be more difficult to construct than other signal wires.
Above are some notes when choosing to buy effective coax cable that Tran Phu Cable shares with you. We are the only unit specializing in providing electrical wire and cable products in the country to receive the "New Millennium" award, the European quality award in 2006 awarded in Paris (France). Tran Phu M&E is the only enterprise in the North in the electrical cable manufacturing industry that has obtained the national brand certification (VietNam Value) for many consecutive years, along with valuable awards such as: 11 consecutive years of winning the title " High quality Vietnamese goods (2009-2020).
