You may be interested to know where and in which country the self-supporting low voltage power cable was used for the first time and what is its price. Stay with us to find the answer to this question. It should be mentioned that self-supporting low pressure electric cable was used for the first time in France in the 20th century, and due to its advantages, the use of this type of cable increased all over the world.
Self-preservation is not very old. One of the features of this type of cable is its superiority over non-annealed copper cables. Also, the presence of insulation on this type of wire reduces the risk of connection between strands and theft from the power grid.
It should be mentioned that self-supporting cables are divided into two groups, high pressure and weak pressure.
Self-supporting cable has features that separate it from other cables. These features include the presence of xlpe insulation in these types of cables. Also, these cables have an aluminum conductor and a holding wire, and this wire is made of steel for 20 kW cables and aluminum for weak pressure cables.
The price of low voltage power cable
In this section, we want to provide information about low voltage power cables, including the price and use of these types of cables, so stay with us so that new information is added to you. These types of cables are usually used to transmit electricity with a voltage between 500 and 1,500 and also due to the allocation of this type of cable to low pressure electricity, it is used in cases such as street lighting and building wiring. In all of these types of light-emitting cables, there is a zero wire that has a gray color and the protective wire has a red colorAnd in this type of cables, there are threads with other colors such as blue and green, which are colored according to the type of thread. There are many differences between high pressure and weak pressure cables, and you should prepare each of the cables you need according to your needs, and one of the features that makes the difference between high and weak pressure cables is the different structure of these two types. It is cable.
In the structure of the high voltage cable, several conductors and semiconductors are used, and this feature is because high voltage cables are used for high voltage transmission, and in this case, external currents should not interfere with the magnetic field that is inside There are cables, but in low pressure cables, having this feature is not very important due to the use of low pressure cables.
Self-retaining low voltage power cable
It is interesting to know that this type of cable, i.e. self-sustaining low pressure electric cable, is divided into different groups. Self-sustaining low pressure electric cable is divided into four groups based on the number of strands. The first node, which is called a two-strand self-sustaining cable, is It consists of a phase string and a neutral string, and this type of cable is used for those who need a single-phase cable. The second type of these cables is the three-core self-supporting weak pressure cable, and this type of network cable includes one phase and one neutral.
In addition, this type of cable has one strand more than the previous type, which is used for street lighting, such as electric lights in highways and city streets. The third type of self-sustaining cables has three phase strands and also has a lighting strand to turn on the street lights and a neutral strand. In total, this type of cable has five strands, so this type of cable is also a five-strand self-sustaining cable. they say.
The last type of this type of division is the six-stranded self-sustaining cable. This type of cable has three phase strands and one neutral strand, as well as one strand for street lighting, the strand that is placed in this type of cable has caused a If it has more strands than the five-stranded self-maintaining cable, it is a retaining strand. The conductor cable that is used in the self-sustaining low voltage power cable must be made of aluminum and it must also have a purity of 99% and regarding the insulation of this type of cable, it can be stated that this type of insulation is made of polyethylene and usually black in color. . This type of insulation is very resistant to heat and heat, and also this type of insulation has an extremely high tolerance against other atmospheric factors such as ultraviolet rays and physical factors such as stretching and abrasion.As it was said in the text above, self-supporting low voltage power cables have advantages over other cables, and this has made the use of this type of cable to be used more often compared to old cables, and one of the factors that cause this The following things have happened.
Due to its technology and structure, this type of cable is able to reduce unauthorized branching to a significant amount. Also, due to its appearance, this type of cable has also made the urban space more beautiful. These types of cables are much safer than the cables that were used in the past, due to the presence of a protective layer or insulation, and this factor has prevented the occurrence of risks such as short circuit in electric cables, as well as the structure of this type. Cables have also reduced energy drain. Self-supporting weak tension power cable can be installed on any type of power pole in different sizesAnd it is very easy to install these types of cables on the electric pole, and also the cost of installing these types of cables is very low due to the easy installation of this type of cable, and the maintenance cost of these types of cables is also very affordable. If you need a low voltage power cable to use it in various cases such as building electricity or street electricity, you can visit our site and get this product at a reasonable price.
