FAQ

Q. How does 110kV XLPE cable differ from traditional ones?

A. XLPE (cross-linked polyethylene) insulation provides higher thermal resistance and longer lifespan than oil-paper cables, reducing maintenance costs.

Q. What factors affect 110kV cable capacity?

A. Key factors include: ambient temperature, conductor material (e.g., aluminum vs. copper), and installation depth (for underground systems).

Q. Can 110kV cables be used in submarine environments?

A. Yes, with special waterproof armor and corrosion-resistant coatings, but costs increase due to engineering complexity.

Q. How to monitor faults in 110kV cable networks?

A. Techniques include: partial discharge (PD) sensors, distributed temperature sensing (DTS), and AI-based predictive analytics.

Q. What are the latest cooling technologies for high-voltage cables?

A. Innovations like liquid-filled cooling systems and phase-change materials help dissipate heat, enhancing load capacity by up to 30%.

Q. How long is the typical lifespan of a 110kV cable?

A. With proper maintenance, XLPE cables last 40–50 years, while older oil-paper types may degrade faster.

Q. Are superconducting cables feasible for 110kV applications?

A. Emerging high-temperature superconducting (HTS) cables show promise but remain costly; commercial adoption is still limited.

Q. What safety standards apply to 110kV cables?

A. Compliance with IEC 60287 (rating calculation) and IEEE 400 (installation guidelines) is critical for reliability.

Q. How to reduce energy loss in 110kV transmission?

A. Optimize conductor size, use low-loss dielectric materials, and implement dynamic line rating (DLR) systems.
