The Difference Between Communication Cables And Power Cables

There are many types of cables. Power cables and communication cables are two types of cable products. What is the difference between similar cables and cables?

The communication cable is a high-frequency carrier digital communication and signal transmission cable used for short-distance audio communication and long-distance communication. It consists of a cable core composed of several optical fibers and an outer sheath. It is the most promising communication transmission medium on the market. Furthermore, it is widely used in telephone, telegraph, fax, television, and radio programs. And will become the main body of the future communication network.

Fiber optic lines
Fiber Optic for Internet

A power cord is a cable that transmits and transmits electrical energy. Commonly used in urban underground power grids, power station leads, internal power supplies of industrial and mining enterprises, and underwater transmission lines crossing rivers and seas. At present, the proportion of wires and cables has gradually increased. Wires and cables are the main products used by power systems to transmit and distribute power, including various voltage levels of 1-500KV and above, and various insulated power cables.

In short, a cable provides power to a certain area or a certain device. It is also called a communication cable. A cable is used to transmit telecommunication numbers. It is weak electricity and strong electricity, and weak electricity does not die. The power cable determines whether the computer can be powered on, and the communication cable determines whether the computer can access the Internet.

Communication cables are cables that transmit, telegrams, faxes, television and radio programs, data, or other electrical signals. It is formed by twisting more than one pair of mutually insulated wires. Compared with overhead open wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and freedom from natural conditions and external interference.

Wires and cables are cable products mainly used to transmit and distribute high-power electrical energy in power systems, including various voltage levels of 1-500KV and above, and various types of insulated power cables.


Power Cable of Coaxial Cable

Coaxial cable is a kind of transmission medium that many friends are familiar with. It is a cable wrapped with a layer of insulated wire to wrap the central copper wire. Its biggest feature is a strong anti-interference ability, stable data transmission, and low price. However, in the past, coaxial cables were used more, mainly because the cost of the coaxial cable network constituting the bus structure was low, and the damage to a single cable would paralyze the entire network and make maintenance difficult, which is its disadvantage. Coaxial cables currently used in Ethernet are mainly divided into thick coaxial cables and thin coaxial cables.


Fiber Optic Cable

As a new generation of transmission media, optical fiber network has been greatly improved in terms of security, reliability, network structure, etc. compared with copper media. In addition, the bandwidth transmitted by optical fiber far exceeds that of copper cable, and the maximum distance it supports is more than 2 kilometers, which is an inevitable choice for building large-scale networks. Because the fiber optic cable has the advantages of good anti-electromagnetic interference performance, strong confidentiality, fast speed, and large transmission capacity, its price is also relatively expensive, and it is rarely used in home situations.

The cable is divided into high voltage and low voltage. If the voltage is higher, there is a layer of resin-like filler inside, which plays an insulating role. The insulation in the high-voltage cable is very important. Low pressure doesn’t do that. Next, it will have something like a ribbon wrapped around it to hold each core of the cable and fill in the gaps between.
