Electric Wire cable RG6 RG11 RG58 RG59 RG179 RG213 Oxygen-Free Copper Core Coaxial Cable For Outdoor Cable TV Line
Products Description
Coaxial cable (Coaxial Cable) is a kind of wire and signal
transmission line. It is generally made of four layers of
materials: the innermost is a conductive copper wire, and the
outside of the wire is surrounded by a layer of plastic (used as an
insulator and dielectric). There is a thin layer of mesh conductor
(usually copper or alloy), and then the outermost layer of
insulating material is used as the outer skin of the conductor.
Coaxial cables can be used for the transmission of analog and
digital signals, and are suitable for a variety of applications,
among which the most important are cable television transmission,
long-distance telephone transmission, short-distance connections
between computer systems, and local area networks. Coaxial cable
grew rapidly as a means of distributing television signals to
millions of homes, known as cable television. A cable TV system can
load dozens or even hundreds of TV channels, and its transmission
range can reach tens of kilometers. Coaxial cables have long been
an important part of long-distance telephone networks. Today, it
faces increasing competition from fiber optics, terrestrial
microwaves and satellites.
Application range
Coaxial cables have a wide range of applications. Coaxial cables can transmit analog and digital signals in a low-loss manner, and are suitable for various applications. Among them, TV broadcasting systems, long-distance telephone transmission systems, and computer systems are common. Short-distance jumper and LAN interconnection, etc.
Coaxial cables are divided into two types according to different impedance values, 50Ω and 75Ω, of which the 50Ω model is used for digital signal transmission, and the 75Ω signal is used for video signal transmission.
Coaxial cable grew rapidly as a means of distributing television signals to thousands of homes, known as the cable television network. A cable TV system can load dozens or even hundreds of TV channels, and its transmission range can reach tens of kilometers.
History development
The development of coaxial cables is mainly divided into four
generations: the first generation began to use polyethylene
material as the solid core insulation medium in the middle of the
19th century; the second generation used chemical foaming PE
material as the insulation medium; The porous PE material is used
as the insulating medium; the fourth generation uses physical
foamed PE material as the insulating medium. According to the
structure, coaxial cables can be divided into: leaky coaxial
cables, multi-core coaxial cables, thinned coaxial cables, and
composite coaxial cables.
The coaxial cable industry has experienced a series of changes so
far. As the global electronics industry entered its peak period in
2000, as a part of the electronics industry, the coaxial cable
market also reached its historical peak. In the following three
years, as the global economic growth rate entered a trough, the
coaxial cable industry also entered a downturn period with the
shrinking downstream demand, and there was no sign of recovery
until the second half of 2003. Since 2004, the global coaxial cable
industry has entered a new round of growth. With the continuous
expansion of mobile communication signal coverage, the expansion of
the number of base stations, and the continuous improvement of
mobile signal requirements in the fields of transportation, energy,
and medical care, the market development prospects of the global RF
coaxial cable industry are still promising.
