Robust and highly efficient, these cables are engineered specifically for high-capacity trunk transmission and backbone grid infrastructure. Featuring a conductive core of ultra-high-purity oxygen-free copper (or premium aluminum alloy) and advanced cross-linked polyethylene (XLPE) insulation, they offer exceptionally low resistance loss and superior resistance to thermal aging. The product range spans high, medium, and low voltage categories, with customizable options for specialized outer sheaths—including flame-retardant (FFX), fire-resistant, low-smoke zero-halogen (LSZH), and anti-termite/moisture-proof varieties. Designed to handle high-power loads while ensuring long-term operational safety and stability, they serve as the vital arteries for urban power grids, large-scale industrial complexes, and major infrastructure projects.
