What does CAT3-25P-UTP and CAT.6-4P-UPT mean in the light current integrated wiring system diagram ?

CAT3-25P-UTP and CAT.6-4P-UPT are the signs of twisted pair in the light current integrated wiring system diagram.

CAT3 represents three types of twisted pairs, and CAT.6 is six types of twisted pairs. In practice, the latter is rarely used. According to the development history, he should have CAT3, CAT4, CAT5, CAT6, and CAT7.

25P means 25 pairs, that is, 25 pairs of lines. His actual should be 25pair, which is a large-pair cable for the trunk system.

4P means 4 pairs, that is, 4 pairs of wires. It is generally sold in the world. This is the cable used in the work area, the traditional twisted pair.

UTP means unshielded twisted pair, and in reality there is STP, which means silk screen shielding. SFTP, it is a double shield, the best on the market, wire mesh shield plus aluminum foil shield.

Electric power applications can be divided into two categories according to the strength of power transmission power: strong electricity and weak electricity. The electricity consumption of buildings and building complexes generally refers to strong electricity with AC 220V50Hz and above. It mainly provides electric energy to people and converts electric energy into other energy sources, such as air conditioning electricity, lighting electricity, power electricity and so on.

There are two main types of weak electricity in intelligent buildings. One is low-voltage electrical energy such as the safety voltage level and control voltage stipulated by the state. It is divided into AC and DC. Back-up power for lights. The other type is information sources that carry information such as voice, image, data, etc., such as telephone, television, computer information.

Integrated wiring is a modular, highly flexible information transmission channel within or between buildings. Through it, voice equipment, data equipment, switching equipment and various control equipment can be connected with the information management system, and at the same time, these equipments can be connected with the external communication network.

It also includes all cables and related connection components between the connection point of the network or telecommunication line outside the building and the application system equipment. Integrated wiring consists of components of different series and specifications, including: transmission media, related connection hardware (such as patch panels, connectors, sockets, plugs, adapters) and electrical protection equipment. These components can be used to build a variety of subsystems, each of which has its own specific purpose, is easy to implement, and can be smoothly upgraded as requirements change.
