What is XLPE cable and what is its use?
XLPE cable is called a cable whose cover is made of XLPE material. XLPE is polyethylene whose molecules are linked together in the shape of X (Cross-linked polyethylene). XLPE insulation has several features that we will discuss in this article. We also take a look at the applications of this cable and check its difference with PVC cable.
What is XLPE insulation?
Polyethylene or cross-linked polyethylene is a material used in making XLPE cable. The cross structure of molecular bonds in this material causes heat resistance. XLPE’s heat resistance makes this cable a suitable option for high voltage electricity transmission.
Another important feature of this material is its high tensile and bending strength. The water absorption of this material is about 0.01% and its dielectric constant is 2.2. As we said, XLPE is a thermal insulator and its melting temperature reaches something around 150 to 170 degrees Celsius.
Density of XLPE and its other properties
In the previous section, we introduced some properties of crosslink polyethylene (XLPE) insulation. To learn more about this material and its important features, we add other items in this section.
One of the important features of this cable insulation is its low density. The density of XLPE is about 0.92 grams per cubic centimeter. This makes the XLPE cable light weight. Although the melting point of this material is something around 150 degrees Celsius. However, its working capacity reaches 90 degrees Celsius.
XLPE insulation is halogen free. This causes the absence of dangerous gases during a fire.
Under what conditions should XLPE cable be used?
In different situations, it is necessary to use XLPE cable. Because in this condition, other cables cannot function properly and the transmission of electricity may be disrupted. In the following cases, it is better to use XLPE cables.
in high temperature environments; As we said, XLPE is a strong heat insulator. It is mandatory to use XLPE cables to prevent the cable from melting.
high voltage transmission; Another case in which the use of this type of cable is necessary is the transmission of high voltage electricity.
wear and tear; In industrial environments, cables are sometimes exposed to wear or even pressure. Cross-linked polyethylene cables can withstand pressure, abrasion and cutting well.
water and other liquids; The water absorption of XLPE insulation is very low. Therefore, it is better to use this cable when the cable is exposed to water and other liquids.
chemicals and other corrosive substances; Another important feature of XLPE insulation is resistance to corrosive and chemical substances. Therefore, if you need to transmit electricity in such conditions, it is better to use XLPE wire.
Application of XLPE cable in various industries
In various industries, the conditions that we reviewed in the previous section prevail. For example, it is necessary to use XLPE cable in mines. It is better to use this cable in the chemical industry.
XLPE cables can also be used in large commercial units and even residential complexes. In general, in situations where there is a possibility of fire due to cable contact with oil and other corrosive liquids, XLPE cable is the best option.
XLPE cables are used in factories, refineries and mines. Because in such environments, cables are usually exposed to various abnormal conditions such as pressure and tension, wear, chemicals and corrosive substances.
Difference between xlpe and pvc cable
As we said earlier, XLPE insulation is a polyethylene material whose molecules are linked together in the form of X. In contrast, PVC insulation is a polyvinyl chloride. One difference between XLPE and PVC cable is that XLPE can withstand conditions such as high tension very well. In fact, the structure of this insulation is such that it has significant resistance to wear and tear.
On the other hand, PVC cable cannot withstand much pressure. This cable is more suitable for applications where the cable is not under much tension. In the following, you will read the important differences between these two types of cables.
The durability of XLPE insulation is much higher than that of PVC insulation.
Another advantage of XLPE over PVC is the absence of chloride in its structure. This issue makes this insulation more compatible with the environment.
XLPE cable can withstand higher temperature than PVC.
Cross-linked polyethylene (XLPE) is more resistant to moisture than PVC. In fact, the resistance of XLPE against moisture is 100 times higher than that of PVC.
In some cases, both of these materials are used for cable insulation. In this way, the main insulation used in the cable is made of XLPE and the final covering of the cable is made of PVC.
Price of xlpe cable
Cable price is determined according to various factors. You will read some of these below.
The type of conductor used in the cable
Insulation type
The number of strands in the cable
Application
The amount of voltage that can pass through the cable
Now we can take a look at the price of XLPE cable according to the above. XLPE insulation is a much more efficient material than PVC. Therefore, it is obvious that the price of XLPE cable is higher than many cables.
Also, this cable can transmit electricity with very high voltage. Various applications are another important advantage of this cable. These things affect the price of the cable and cause its price to differ from other types of cables.
