Restraints

• High Installation and Maintenance Costs

• Environmental ConcerEnvironmental Concerns:The environmental impact of laying submarine cables, including potential disturbances to marine ecosystems and habitats, poses a challenge. Regulatory requirements and environmental protection measures can complicate project implementation and increase costs, acting as a restraint on market growth

  Mass-impregnated cables and self-contained fluid-filled cables pose environmental concerns due to their reliance on insulating oils and fluids. SCFF cables, in particular, require continuous monitoring to prevent leaks, as any fluid leakage can contaminate soil and water sources, leading to environmental hazards. Additionally, the disposal of these cables at the end of their lifecycle presents challenges, as the insulating materials and metallic components need careful handling to prevent pollution. The extraction and processing of materials used in these cables, such as lead sheathing and oil-based insulation, also contribute to environmental degradation.

  Extruded insulation cables, especially those using cross-linked polyethylene (XLPE), offer a more environmentally friendly alternative. These cables eliminate the need for liquid insulation, reducing the risk of leaks and contamination. However, concerns remain regarding the recyclability of polymer-based insulation materials, as XLPE is not easily biodegradable. Advances in material science are focused on developing recyclable and low-impact insulation materials to further reduce the environmental footprint of high-voltage power transmission systems. As energy infrastructure transitions toward sustainability, minimizing the ecological impact of cable technologies remains a critical consideration.The installation and maintenance of submarine electricity transmission systems are associated with high costs. Laying cables on the seabed and maintaining them in harsh underwater environments require significant investments, which can be a major barrier for market expansion, especially in regions with limited financial resources.
