Cable extrusion material series refer to a range of materials used in the production of cable insulation and sheathing through the process of extrusion. The materials used in cable extrusion can vary depending on the specific requirements of the cable, such as voltage rating, environmental conditions, and mechanical strength.
Some of the common materials used in cable extrusion include:
Polyethylene (PE): PE is a widely used material in cable extrusion due to its excellent electrical insulation properties, high flexibility, and resistance to moisture and chemicals. It is commonly used in low and medium voltage power cables.
Cross-linked polyethylene (XLPE): XLPE is a thermosetting material that is produced by cross-linking PE molecules. It offers improved insulation properties compared to PE, and is commonly used in high voltage power cables.
Polyvinyl chloride (PVC): PVC is a widely used material in cable extrusion due to its low cost, high flexibility, and resistance to chemicals and weathering. It is commonly used in low and medium voltage power cables.
Ethylene propylene rubber (EPR): EPR is a synthetic rubber material that offers excellent electrical insulation properties, high flexibility, and resistance to heat and chemicals. It is commonly used in medium voltage power cables.
Chlorosulfonated polyethylene (CSPE): CSPE is a synthetic rubber material that offers excellent resistance to weathering, ozone, and chemicals. It is commonly used in cables that are exposed to harsh environmental conditions.
Overall, the selection of cable extrusion materials depends on a range of factors such as the application requirements, performance specifications, and cost considerations. The material series used in cable extrusion can be customized to meet specific requirements of the cable application.
