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.

The design, construction and testing are compliant with international standard IEC60502 and testing standard EN 50200 (PH-90),with standing temperatures of 840 °C for 90 minutes, which means they are capable of remaining in working order despite the most extreme fire conditions. Hence they are known as FIRE RESISTANT cables.

This type of cable is made up of single and multi-cores 600/1000V cables Service Temperature 90°C Emergency Overload Temperature 105°C Short-Circuit Temperature 250°C

Installation of these cables is essential in safety circuits (detection and alarm circuits,evacuation and fire-fighting systems).

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%.
