630mm2 High Voltage Power Cable with XLPE Insulation and Copper Screened for Power Transmission

APPLICATION

630mm² high-voltage power cable with XLPE insulation and copper screened is primarily used for transmitting electrical power in high-voltage applications. Its cross-linked polyethylene (XLPE) insulation provides excellent dielectric strength and thermal stability, while the copper screen offers effective electromagnetic shielding and ensures reliable grounding. This type of cable is commonly employed in power distribution networks, industrial plants, and infrastructure projects where high power transmission capacity and durability are required.

FAQ

1. What is the typical voltage rating of a 630mm² XLPE insulated copper screened cable?‌

Designed for ‌66kV–110kV‌ high-voltage transmission systems, with options up to 220kV for specialized applications.
2. What is the role of the copper screen in this cable?‌
The copper screen provides ‌electromagnetic shielding‌ to prevent interference, ensures ‌uniform electric field distribution‌, and acts as a ‌grounding path‌ for fault currents.
3. Where are these cables commonly installed?‌
Used in ‌urban power grids, industrial complexes, substations, and renewable energy projects‌ (e.g., wind/solar farms) requiring high power capacity over long distances.
4. What is the maximum current carrying capacity of a 630mm² cable?‌
Typically ‌800–1,000A‌ at 90°C, depending on installation method (e.g., underground, air, or duct) and ambient conditions.
5. Can this cable be used for underground installations?‌
Yes, it is ‌suitable for underground burial‌ due to its moisture-resistant XLPE insulation and robust outer sheath.
