XLPE Cable Pelletizing Extrusion

In Cross-linked polyethylene process, twin screw extruder has many advantages that traditional equipment can't reach, because of hihg torque level, accuracy heat control and mass transfer, interface renewal capability, narrow residence time distribution, excellent heat transfer and stripping ratio surfaces.

What is Cross-Linked polyethylene (XLPE)?

XLPE Cross-linked polyethylene (XLPE) is produced from a cross-linking process of polyethylene (LDPE) resin. The long-chain branched structure of LDPE makes it easy to cross-link and achieve a higher degree of cross-linking, making it the preferred material for high-voltage XLPE power cable insulation.


Applications of cross-linked polyethylene (XLPE).


XLPE is widely used in building service piping systems, hydraulic radiant heating and cooling systems, domestic water pipelines and high-voltage cable insulation.It can be used for high-voltage, ultra-high-voltage and ultra-high-voltage cables of 110 kV and above, suitable for grid transmission, offshore wind power, hydropower stations and other fields and some large industrial projects.


Advantages of XLPE Insulation Material:


XLPE insulation offers several advantages over traditional materials such as polyvinyl chloride (PVC).

·        Thermal stability: XLPE can withstand high temperatures without deformation, making it suitable for high-pressure applications.

·        Chemical resistance: The cross-linked structure has excellent chemical resistance, ensuring durability in harsh environments.

·        Mechanical strength: XLPE has excellent mechanical properties, including resistance to wear and stress cracking.
