Underground cable is often armored because they need to protect it in the form of corrosion, damage or even rodents eating cable cover and the price of armored cable is higher than the armored cable.
Xlpe as a strong branch of PE is an ideal option about armored cable.
1. XLPE armored cable
Ultra-low permeability electrical insulation, abbreviation is XLPE.
XLPE is a common electrical insulator used in underground power cables. XLPE has exceptional resistance to oil, water and other chemicals.
This system is resistant to extreme temperature. XLPE is used in high pressure applications that are exposed to water, oil or corrosive materials.
2. XLPE Armor
An insulating conductor with XLPE is placed in XLPE armor. XLPE armor to protect XLPE insulation against damage during installation and use.
3. String of interconnected polyethylene
XLPE wire is an insulated conductor with XLPE and is available in a range of diameter.
The only difference between XLPE wires and standard XLPE insulating conductors is the absence of an outer jacket.
Depending on its usage, the price difference between armored and non-armored cables may vary.
If you choose to buy a cable length, the price is determined by the number of meters ordered.
If you wish to buy a lot of cable lengths, however, the price per meter will have a significant impact.
Factors affecting the cost of armored cables
Several variables affect the price of armored cables including:
Meters purchased – If you need a certain length of cable, you should assess how much you wish to pay each meter.
Application Type – A certain type of armored cable may be required for a specific application. For example, installing an electrical keyboard requires a different type of armored cable than a protected power cord.
Grades – Different degrees of armored cable provide different degrees of protection and durability.
Types of Armored Cables Available
There are two kinds of armored cable: single wire and two wires.
A single conductor with a single layer of steel is made in single wire armored cables. Two armored cables contain two conductors which surround a central insulator. All kinds of armor.
Advantages of Armored Cables
The use of armored cable provides many advantages over the use of conventional cable and without armor. These are:
Corrosion protection – Metal shielding protects water-exposed wires from corrosion and damage.
Anti-Electrostatic Discharge (ESD) – Metal Shield Defense against Electrostatic Discharge, which happens when static electricity accumulates on individuals or objects.
Safety to electromagnetic interference (EMI) – Shield prevents external interference in the transmission of the cable signal.

No wonder the armor XLPE is now the most popular type of high voltage power cable.
The plant was built in 1980, in an effort to reduce the occurrence of electric shock incidents.
XLPE cables are made with two layers of polyethylene, one layer next to the other. The cross-linking of these inner layers makes them stronger than conventional PE wires.
XLPE is continuously used in power transmission networks, substations, and industrial applications, among other locations.
The cross-linking method requires the use of basic oxide chemicals.
These combinations unite the molecules of polyethylene to make it excellent durable. The final product is a cable that is stronger than the original PE cable.
Cross connection makes XLPE oil and water resistant cable and the ability to withstand high temperature without melting.
XLPE cables offer various advantages over conventional PE cables. One, they’re stronger and more durable.

Moreover, they have a long life span. XLPE cables are less prone to corrosion than conventional PE cables and do not melt when heated.
Finally the cost of producing these cables is lower than that of PII wires.
A significant decrease in XLPE cables is that they are difficult to manipulate.
It takes time to cut and split the XLPE cable, but it becomes simple when you feel it. XLPE cable is also not suitable for use in all situations, which is another lower side.
If you stay in very cold weather, XLPE cable may not be appropriate.
A material used for coaxial polyethylene cables is called an XLPE.
The cross-coupling that occurs between plastics molecules is where the term “plastics” comes from.
These links are created by applying high pressure and high temperature during the manufacturing process.
Wires placed in a power cord are protected with XLPE to protect them from anything sharp they might contact. If broken wires are not fixed in the correct way, there is a risk of spark and fire.
The purpose of XLPE armor is to prevent wires inside a cable that will be damaged if the cable itself is cut off.
When in contact with moisture, the cable is placed under an expansion process.
As a result of this expansion, the wire insulation may be broken and exposed. Wires become vulnerable when exposed.

To prevent this from happening, the XLPE armor creates a barrier between the star and its surroundings. XLPE is a cross-linked polyethylene used in the applications of underground application.
It’s a kind of plastic that’s interconnected to make a durable material. It is thicker and more corrosion-resistant than ordinary copper cables.
The purpose of armored cable is to prevent physical damage. These wires are wrapped around the steel armor for added protection.
The cable is protected by three layers. The first layer consists of PVC insulator, the second layer of aluminum tape, and the third layer is XLPE.
Chemical cross-linking is between two different substances. In this example, we will check the XLPE against PVC. When these two chemicals are combined, a stronger material is produced.
A coating is a material that is placed on the surface of an object to improve its appearance.
In this example, XLPE is covered by an aluminum strip.
A metallic armor is attached around the outer part of the armored wires to protect them. “This prevents anyone from crushing them and causing internal damage.
