FAQ

What is the primary application of a 64/110kV 1x630mm² HV power cable?‌

Designed for high-voltage power transmission in urban grids, industrial zones, and renewable energy projects (e.g., wind/solar farms).

‌Which international standards does this cable comply with?‌

Meets IEC 60840 (AC testing) and IEC 62067 (DC testing) for reliability in both AC and DC systems.

‌What conductor material is used in this cable?‌

Typically employs high-purity copper or aluminum conductors for low resistance and high conductivity.

‌How is the insulation layer designed for 110kV?‌

Features cross-linked polyethylene (XLPE) insulation, ensuring durability and resistance to high temperatures and electrical stress.

‌What are the voltage ratings (U₀/U/Um) for this cable?‌

Rated at 64/110kV (U₀: 64kV, U: 110kV, Um: 126kV), suitable for long-distance transmission.

Can this cable be used in underground installations?‌

Yes, it is designed for direct burial or ducting, with armor options (e.g., steel wire) for mechanical protection.

‌How is the shielding layer structured for high voltage?‌

Includes semi-conductive layers and metallic shielding (e.g., copper tape) to control electric fields and prevent corona discharge.

‌What are the bending radius requirements during installation?‌

Minimum bending radius is typically 20 times the cable diameter to avoid damage to the insulation.

‌How does this cable support renewable energy integration?‌

Enables efficient connection of large-scale wind or solar farms to the grid, minimizing energy losses over long distances.
