Copper isn't widely used for high-voltage transmission lines for several key reasons: Cost: Copper is significantly more expensive than aluminum, which is the most commonly used material for high-voltage lines. Since transmission lines cover vast distances, the cost difference between copper and aluminum adds up considerably, making copper much less economical. Weight: Copper is denser and heavier than aluminum. Heavier wires require stronger (and therefore more costly) support structures to hold them up, which can make the overall infrastructure more expensive to build and maintain. Corrosion Resistance: While both copper and aluminum can corrode, aluminum forms a protective oxide layer when exposed to air, which helps prevent further corrosion. This makes aluminum more durable in outdoor and harsh weather conditions, which is essential for transmission lines. Electrical Conductivity and Efficiency: Although copper has better conductivity than aluminum (allowing it to carry more c...

  Unmanned Power Sub Station System An Unmanned Power Substation System refers to a modern and technologically advanced electrical substation that operates without the need for constant on-site human presence. These unmanned substations utilize automation, remote monitoring, and control technologies to efficiently manage potential events. Automation and Remote Control The system is equipped with intelligent devices and sensors that automate various tasks such as monitoring voltage, current, temperature, and other parameters. Remote control capabilities allow operators to manage the substation from our command center. Reduced Operation and Maintenance Costs With the elimination of on-site personnel, the operational and maintenance costs associated with manned substations are significantly reduced. Routine maintenance tasks can be scheduled and monitored remotely. Enhanced Reliability and Safety The use of automated systems ensures greater reliability and minimizes the risk of human ...
