Product Introduction
The XLPE Insulated Aluminum Cable, also known in China as YJLHV cable, which refers to an aluminum conductor, XLPE insulated, PVC sheathed power cable,is designed for use in power transmission and distribution systems.
This cable combines the advantages of an aluminum alloy conductor, cross-linked polyethylene (XLPE) insulation, and a polyvinyl chloride (PVC) outer sheath. It is widely used in both low- and medium-voltage electrical systems and is suitable for various environments, providing reliable performance and safety.
Cable Structure
The conductor is made of aluminum alloy (typically AA-6201), offering better tensile strength, corrosion resistance, and electrical conductivity compared to pure aluminum conductors. It is lightweight yet robust, making it ideal for long-distance power transmission.
XLPE insulation provides excellent electrical properties, heat resistance (typically rated up to 90°C), and long-term performance. It is highly resistant to electrical stress and aging, ensuring stable and efficient power transmission over extended periods.
The outer sheath is made of PVC, which offers good mechanical strength, chemical resistance, and cost efficiency. PVC sheaths provide protection against abrasion, UV exposure, and moisture, ensuring cable durability in various installation conditions.
