The cables prove suitable for deep-sea and high-voltage installations because they exhibit superior durability along with an extended service period. The insulation structure provides both electrical stress resistance and mechanical damage defense, which makes them suitable for harsh underwater applications. The advancement of modern polymer-based insulation materials resulted in the gradual reduction of their usage. However, they are still preferred in specific applications where proven reliability outweighs modernization. Their maintenance complexity and environmental concerns drive alternative innovations.

• Oil-filled Cable: The insulation properties of oil-filled cables rely on a circulating oil that keeps dielectric stability and stops electrical breakdown. These cables are the standard choice for high-voltage power transmission over submarine networks since they provide dependable operation between distant stations. Operational life expectancy of the cable increases through continuous oil circulation, which maintains effective heat dissipation while decreasing thermal stress. Environmental reservations along with maintenance complications drive industries to adopt eco-friendly power transmission options instead of traditional effectiveness-driven solutions. Furthermore, the sealed structure of oil-filled cables prevents moisture ingress, ensuring long-term insulation integrity even in harsh underwater conditions. The continuous oil flow also helps in self-healing minor insulation damages, enhancing cable reliability and longevity. However, leakage risks and potential oil contamination pose environmental concerns, prompting stricter regulations on their usage. The high installation and maintenance costs associated with these cables further drive research into alternative transmission technologies. As a result, advancements in dry-type and gas-insulated cables are gaining momentum, offering sustainable solutions with reduced ecological impact.
