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

Details

Mineral Insulated Fire Resistant Cable 0.6/1kV Fireproof Cable

• Conductor: High-purity stranded annealed copper conductor, high conductivity, low resistance, stable electrical performance

• Insulation Layer: High-temperature resistant inorganic mica tape, non-combustible, high insulation, anti-aging

• Filling Layer: Alkali-free high-temperature resistant glass fiber, compact structure, strong pressure resistance and heat resistance

• Inner Sheath: Longitudinal welded corrugated copper tube, integrated forming, good air tightness and waterproof performance, serving as grounding protection layer

• Optional Outer Sheath: LSZH low smoke zero halogen sheath (Mineral Insulated Fire Resistant Cable) / PVC sheath (Fire-proof cable) / no outer sheath (Mineral cable)
