Power cables serve as the vital conduits for transmitting electrical energy across various scales, from local distribution to long-distance transmission. These cables facilitate the transfer of power from generation sources like power plants to substations, and finally to end-users in residential, commercial, and industrial settings. Low voltage power cables (below 1kV) are used within buildings for lighting, appliances, and small equipment, while medium voltage (1kV–35kV) and high voltage (above 35kV) cables are essential for urban grids and intercity transmission. Power cables can be installed underground, overhead, or underwater, with designs tailored to environmental factors—such as armoured sheaths for underground protection or waterproof layers for submarine use. Weidong Technology’s comprehensive product line includes power cables for diverse applications, from interior decoration projects requiring flexible conduits to outdoor engineering that demands weather-resistant jackets, ensuring reliable power delivery while aligning with the sales philosophy of adapting to market needs with speed and reliability.
