Why electrical wiring can not be strong and weak cloth together?
Electronic people are divided into strong electricity (electricity) and weak (information) in two parts. (Power), which is characterized by high voltage, current, power, frequency is low, the main consideration is to reduce the loss, improve efficiency, weak, the power of electricity is very different, The main object is the information, that is, the transmission and control of information, which is characterized by low voltage, low current, low power, high frequency, the main consideration is the effect of information transmission problems, such as information transmission fidelity, speed, breadth ,reliability. In general, weak engineering, including television engineering, communications engineering, fire engineering, security engineering, imaging engineering and so on and for the engineering services of the integrated wiring project. Weakness is for strong electricity. Strong power = (380/220), high pressure regardless.
According to the connection hardware in the integrated wiring system functions to divide: wiring equipment, transfer equipment, sub-line equipment, network Connect the device 3
Wire with 2.5 copper wire can generally need about 150 meters to buy when to color, 2 monochrome a two-color, two-color ground can be used to buy some also have to buy another 30 meters or so 4 square copper Core line for air conditioning line brand can be considered to buy Thai and no matter what line to remember to buy the national standard, do not buy non-standard because it is concealed works, out of the bad repair hot water pipe to buy about 40 meters to buy Jinde, The quality of the protection of the above figures for the number, according to your transformation to buy these things to buy more things to buy before buying with the owner said a lot of retreat to make more recommendations and then back, the province of the road to delay the project progress Oh ~ ~ ~ ~ ~~~~~~~~~~~~
