High voltage power cables for construction are critical for transmitting substantial electrical power over long distances in large-scale infrastructure projects. Designed to handle voltages ranging from 1 kV to 33 kV or higher, these cables feature robust construction with thick insulation layers, such as cross-linked polyethylene (XLPE), to withstand high electrical stresses. Armoring with steel or aluminum tape provides mechanical protection against construction site hazards like digging, crushing, or rodent damage. High voltage cables often include a semiconductive screen layer to prevent partial discharges and ensure even voltage distribution. They are used in power plants, substations, and urban grid networks, where reliable power transmission is essential for construction machinery and temporary facilities. These cables must meet strict industry standards, such as IEC 60502, and undergo testing for dielectric strength, temperature resistance, and long-term aging to guarantee safety and performance throughout the construction project's lifecycle.
