Extra-High Voltage Cables by RRH are designed for the most intensive power applications, operating at 800kV and above to serve large-scale utilities, industrial hubs, and super-sized infrastructure projects. These cables feature ultra-thick, high-performance insulation (such as oil-impregnated paper or advanced polymers) that can withstand extreme electrical fields, ensuring safe operation even under maximum load. The conductors, often made of high-purity copper or aluminum, are engineered for low resistance, enabling the transmission of massive power volumes—ideal for connecting large 发电站 (power plants) to major substations or powering energy-intensive industries like steel manufacturing. RRH’s extra-high voltage cables include reinforced armor and corrosion-resistant jackets, making them suitable for harsh environments, including undersea installations. With strict adherence to global standards, these cables deliver unmatched reliability for critical, high-power infrastructure.
