Qiaopu electrical power cord for indoor installation options

Qiaopu electrical power lines in addition to production for the external construction, the part of the power cord products for low-pressure chamber, so the indoor low-voltage power line is also of concern to our customers and choices. Today, Qiaopu electrical technology section will introduce the next indoor power line installation options:
Indoor low-voltage power line is installed in the room for the transmission of low voltage AC wiring (wire), power cord. Indoor multi-voltage is 220V or 380V, the former is used for lighting and appliances, which are used for three-phase power equipment. Two different purposes, but power lines, cables and methods of selection principle is the same. Indoor power line choice should primarily consider the following four aspects.
First, sufficient mechanical strength and flexibility
Must have sufficient mechanical strength and softness. Mechanical strength is too small, people can not afford to stretch tension, easily broken. Using concealed installations, the power cord to pass through the wall of the pipe fixed, if insufficient mechanical strength, threading process may result in broken wires, so that the fixed mounted or concealed power cord to use more unique root copper or aluminum wire.
Appliance's power cord or temporary outlet into line, as often swap move, the focus should consider the power cord of the softness is generally better to use multi-strand copper wire.
Second, the insulation
Power cord insulation is an important indicator to ensure safe use of electricity. Power cable insulation jacket used in two ways: rubber and plastic. Rubber insulated wire used for AC rated voltage 250V or less, * phase temperature does not exceed +60 ℃ occasions. Plastic insulated wire, can be used for AC rated voltage below 500V or 1000V DC voltage in the following, * phase temperature does not exceed +65 ℃ occasions.
Third, the conductivity
High conductivity copper, aluminum, followed by the same in the case of resistance, aluminum cross-section is 1.68 times the copper wire, copper wire of high mechanical strength than aluminum; aluminum, cheaper, easy to weld .
Fourth, the power line cross-sectional area
The correct choice of power line conductor cross-sectional area, is to ensure safe, reliable, saving one of the most important measures, conductor cross-sectional area, also chose the most important indicator of the power cord.
Power lines safe carrying capacity, depending on the material and cross-sectional area of ​​the conductor, conductor material is established, first cross-sectional area is to be taken into account. Power line in the higher conductivity of the conductor, the greater the cross-sectional area, the greater its safe carrying capacity, with the power cord insulation material, laying, ambient temperature and so on. People taking full account of these factors, a lot of practice, to sum up the development of a common power supply line of safe carrying capacity will be look-up table.
According to the user with the maximum load current conductor materials and laying methods, the table can be found from the corresponding cross-sectional area of ​​the wire. The principle is: the safety wire is equal to or slightly greater than the actual carrying capacity of the current intensity.
To the extent possible, the conductor cross-sectional area should follow the principle rather large not small, have a greater safety factor.
So, Qiaopu electrical While most orders are used for outdoor works installed power cord products, however, indoor power cord involving a wider range of customers, the safety factors involved larger and more. Qiaopu Electrical Technology Section has been stressed that the standard of outdoor power line installation process, but indoors the majority of families can not ignore the safety of customers, it should tell you that these public safety knowledge, I hope people will choose and use power line safety products .
