Mineral insulated Fire resistance cable
YTTW 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.
Rated working voltage:
– Light Duty: 500 V
– Testing Voltage (50 Hz): 2500 V - 15 min
– Heavy Duty: 750 V
– Testing Voltage (50 Hz): 2000 V - 15 min
| — 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.
