CU-LSZH-PVC-XLPE-MINERAL-INSULATED-CABLE

Details

Mineral Insulated Fire Resistant Cable 0.6/1kV Fireproof Cable

Mineral cable is a high-performance mineral insulated fire-resistant cable and LSZH sheathed mineral cable. It features a corrugated seamless copper inner sheath and an extra LSZH (Low Smoke Zero Halogen) outer protective sheath to boost safety and durability. Made with high-purity annealed electrolytic copper conductors and high-density mica tape mineral insulation, it integrates excellent fireproof performance, reliable electrical conductivity and eco-friendly merits, perfect for critical power transmission applications and high fire-safety engineering projects.
