Silane cross-linked low-smoke, halogen-free flame-retardant insulation material relies on silane chemical cross-linking, with low processing equipment threshold and high production efficiency. With excellent temperature resistance, electrical insulation, and anti-aging performance, it is suitable for urban and rural distribution networks and indoor power cables, with lower comprehensive cost, and can meet the regular fire power supply needs of the grid.
