Insulated power transmission cables play a pivotal role in the electrical infrastructure, facilitating the safe and efficient transfer of electrical power over long distances. These cables are designed with multiple layers, where the core conductor, typically made of high-conductivity materials like copper or aluminum, is responsible for carrying the electrical current. Surrounding the conductor is the insulation layer, which is of utmost importance as it prevents the leakage of electrical current and protects against electrical shock. Insulation materials used in power transmission cables are carefully selected based on their electrical, thermal, and mechanical properties. Common insulation materials include cross-linked polyethylene (XLPE), which offers excellent electrical insulation, high-temperature resistance, and durability, making it suitable for medium to high-voltage applications. Polyvinyl chloride (PVC) is another widely used insulation material, known for its cost-effectiveness and good insulation properties in low-voltage systems. Additionally, outer jackets are applied to insulated power transmission cables to provide further protection against physical damage, moisture, chemicals, and environmental factors. The design and quality of insulated power transmission cables are regulated by strict industry standards to ensure reliable power delivery, minimize energy losses, and enhance the overall safety of the electrical grid, whether for urban power distribution or long-distance transmission between power plants and substations.
