They are widely used in industries and high-pressure areas.<\/p><ul><li><strong>Submarine Cables:<\/strong><\/li><\/ul><p>These cables are designed for transmitting electricity under water. Their design and construction are highly complex to resist environmental factors such as water pressure, temperature changes, and chemical exposure.

They are used as long-distance open-air power transmission lines. These cables require suspension and supporting towers and are usually employed to carry electricity from power plants to substations or cities.<\/p><h3><span style=\"color: #181c86;\">Comparison of Various Factors in Three-Phase Power Cables:<\/span><\/h3><ul><li>Load Capacity: Insulated and submarine cables can carry higher loads compared to pure cables.<\/li><li>Resistance to Environmental Conditions: Insulated and submarine cables offer better resistance due to their insulation layers.<\/li><li>Cost: Pure cables are generally more cost-effective, while insulated and submarine cables are more expensive.<\/li><li>Transmission Delay: Overhead cables, due to the absence of insulation, typically have less delay in power transmission.<br \/>Additionally, environmental factors such as climate, soil composition, temperature changes, and exposure to chemicals can affect performance. For example, in colder regions, cables with strong low-temperature performance are more critical.<br \/>Ultimately, selecting the right three-phase power cable depends on needs, environment, and technical as well as economic factors.
