XLPE refers to cross-linked polyethylene. It has some of the same properties as polyethene, such as high chemical resistance and exceptional moisture resistance. Its high thermal insulation properties are ideal for use under both high voltage and high-temperature settings.
Cross-linked polyethylene (XLPE) is often used in constructing plumbing schemes as insulation for high voltage cables and as a replacement for polyvinyl chloride (PVC) and copper tubing in water pipes.
Characteristics of XLPE cable
Good Electrical Properties
Polyethene has excellent electrical properties and a low dielectric loss factor, allowing it to be used at even higher voltages than PVC Insulated Cable. Polyethene has been used as a cable insulant, but its thermoplastic nature limits its uses.
The cross-linking effect inhibits the migration of molecules about each other when stimulated by sunlight, resulting in increased stability at elevated temperatures compared to thermoplastic materials. XLPE cable exporter in Delhi ensures the cab higher operating temperatures, both for normal loading and under short-circuits conditions, resulting in an XLPE cable with a higher current rating than its PVC equivalent.
Polymeric cable insulation is more prone to electrical discharge than saturated paper. It is critical to eliminate gaseous spaces inside the insulation or inner and outer surfaces at higher voltages, where electrical stresses are strong enough to facilitate release. The conductor screen is a thin film extruded in the same operation as the insulation and cross-linked to form a tight bond between the two elements. The screen over the heart may be a contrasting extruded layer or a coat of semiconducting paint covered with semiconducting tape.
Advantages of XLPE Insulated Cables?
High Voltage Transmission
XLPE-insulated cables are suitable for transmitting higher voltage without hindrance or compromise. XLPE insulated cables outperform most insulation technologies due to their exceptional insulation properties.
XLPE insulated cables have outstanding mechanical properties, including but not limited to impact resilience, elongation, and, of course, elevated tensile strength, in addition to their increased chemical properties, which are responsible for their excellent moisture, chemical, and oil resistance.
Using XLPE shielded cables save wires and cable exporters time and money while installing, repairing, and maintaining piping systems and networks.
Transfer High Voltage Electricity
Electrical cables are sometimes used to transfer high voltage electricity from one location to another where power is required. It is not uncommon to encounter flickering, shocking, and heat that could cause fire or other possible dangers when such significant voltage levels are shared continuously.
Similarly, these wires and cables are often moved under or above ground, influenced by the elements.
These problems then necessitate proper insulation to prevent any of the hazards mentioned above. XLPE wire and cables are designed to survive all of these situations while maintaining mechanical properties and performance integrity.
As bare copper wires are insulated with cross-linked polyethylene, they work admirably – and their performance improves! The improved performance of XLPE power cables is quickly gaining popularity, and XLPE power cables are widely accepted in many XLPE cable exporter industries in Delhi.
XLPE power cables are suitable for use in electric works or projects due to their increased water-tree resistance. When exposed to high temperatures, XLPE power cables do not melt. Because of their better mechanical properties, XLPE power cables can hold more load per unit area without fracturing or tearing.
