Flame Retardant Power Cable Mineral Electrical Cable , Mica Tape Insulation Metallic Sheathed Cable
Fire resistance cable YTTW
YTTW Mica Tape flame retardent cable is designed for aboveground
applications.
Engineered to replace conduit and wire applications, this all-in-one cable assembly offers fewer installation steps.
The copper metallic sheath protects the conductors from damage before,during and after installation and provides overall flexibility not available with a conduit.
| — Flame Retardant — High Operating Temperatures — LSOH Halogen-free — Great Mechanical Strength — Competitive Installed Cost — Public Places | Our YTTW cables provide outstanding electrical and fire-proof properties, and are halogen free.

Notes:
Ampacities based on 90°C conductor temperature and 40°C ambient temperature according to IEC 287 standard
The voltage drop based on conductor temperature 90°C is on the high side calculated only for reference
When the cable adopt compressed cores, diameter of cable should be 95% of normal diameter, diameter of metallic sheath should be adjusted correspondingly. When enhancing the insulation, outer diameter of cable is increased for about 5%.
