What Is XLPE Cable?

XLPE cable (Cross-linked polyethylene) is a type of electrical cable commonly used for power transmission and distribution. XLPE cable is made of a thermoset material, which means it is highly resistant to heat, moisture, and chemicals. This makes it an ideal choice for applications where the cable will be exposed to harsh environmental conditions, such as underground or underwater installations.

The XLPE insulation material is produced by chemically cross-linking polyethylene molecules. This process enhances the material's strength and stability, improving its ability to withstand high temperatures and electrical stresses. XLPE cable has a higher operating temperature compared to PVC (polyvinyl chloride) insulated cables.

What Are The Benefits Of XLPE?

The benefits of XLPE make it a preferred choice for applications where electrical insulation, chemical resistance, thermal stability, and mechanical strength are crucial factors. Its versatility and reliability have contributed to its widespread use in power transmission, cable manufacturing, automotive, aerospace, and other industries. XLPE insulation performs at both high and low temperatures. Due to its structure, XLPE is extremely resistant to abrasion and other wear and tear. It also boasts resistance to high-voltage electricity, chemicals, and other hazardous materials. Cross-linked polyethylene insulation is also a more affordable option.

When Should XLPE Cable Be Used?

XLPE cable is commonly used in a wide range of applications, including power distribution in buildings, industrial installations, and utility power grids. It is available in various sizes and configurations, including single-core, multi-core, and screened cables. It can also be used for low-voltage, medium-voltage, and high-voltage Cross-Linked Polyethylene applications.

In short, XLPE cable should be used in industries that expose wire and cable to:

• Extreme temperature conditions (high and low)
• High-voltage electrical applications
• Abrasion and stress
• Water and other liquids
• Chemicals and other hazardous materials

XLPE cable can be used for plumbing, mining, and various electrical applications. Cross-linked polyethylene cables can also be found across the chemical industry and within the commercial and residential heating industry. Don't forget about dentists' offices and other medical institutions, groundskeeping at stadiums and other venues, and much more.

What's The Difference Between XLPE Insulation And PVC Insulation?

XLPE, as explained above, is cross-linked polyethylene material. PVC stands for polyvinyl chloride insulation.

The main difference is that XLPE can be used for high and low-tension applications. Its structure provides great resistance to abrasion, stress, and other wear and tear. PVC insulation cannot withstand as much pressure, meaning it is only suitable for low-tension applications.

Other differences:

• XLPE insulation tends to last longer than PVC insulation
• Since XLPE doesn't contain chloride, it is more environmentally friendly
• XLPE insulation can withstand higher temperatures
• Cross-linked polyethylene features more moisture resistance

The insulation materials of the cross linked polyethylene insulated cable

What is primarily good about the cross linked polyethylene insulated cable is the insulating materials. Insulation is defined as that the insulating materials are coated on the outside of conductors with different thicknesses according to the requirements of its voltage withstanding degree , which plays the role of isolating charged bodies from other parts. After the cable is electrified, the conductor will heat up. Therefore, the ideal type of insulation material should have good insulation performance and good thermal conductivity.

Cross linked polyethylene insulated cable uses chemical or physical methods to change the molecular structure of cable insulated polyethylene from linear molecular structure to main network molecular structure, that is, changed from thermoplastic polyethylene into thermosetting cross linked polyethylene, and thus greatly improves its heat resistance and mechanical properties, reduces its shrinkage, prevents it from melting after being heated, and maintains excellent electrical properties. Therefore, Cross linked polyethylene insulation has good advantages in heat resistance and mechanical properties, and has become an ideal insulation material at present.

The cross linked polyethylene insulated cable improves the performance of polyvinyl chloride insulated cable

The long-term working temperature of the polyvinyl chloride insulated cable is only 70', while the long-term allowable working temperature of the cross linked polyethylene insulated cable can reach 90'. And the cross linked polyethylene insulated cable can maintain an elastic state at a temperature of 130'. The insulation specific gravity of cross linked polyethylene is 0.92g/cm3. According to the standard, the thickness of the cross linked polyethylene insulation is allowed to be thinner than that of polyvinyl chloride insulation. Therefore, the cross linked polyethylene insulated cable is widely used because of their lighter weight, smaller diameter, convenient installation and laying, and simple fittings, in comparison with the polyvinyl chloride insulated cable.

The cross linked polyethylene insulated cable is widely recognized and applied by users in various fields because of its outstanding characteristics such as simple structure, light weight, no drop limit for laying, high allowable temperature, good heat resistance, large current carrying capacity, non-melting, chemical corrosion resistance and high mechanical strength.

What are the advantages of the cross linked polyethylene insulated cable?

The cross linked polyethylene insulated cable has excellent thermo-mechanical properties, excellent electrical properties and chemical corrosion resistance, and has the advantages of simple structure, light weight and unlimited laying. It is a new type of cable widely used in urban power grids, mines and factories at current society.

The cross linked polyethylene is a cross linked polyethylene whose linear molecular structure is transformed into three-dimensional network structure by chemical or physical means.
