Firetox Flame Retardant Cables 

Firetox Flame Retardant Cables

600/1000V XLPE Insulated, LSZH Sheathed, Screened Power Cables (3C+3E)

FTX300 1RCZ1-R (CU/XLPE/CUTO/LSZH 600/1000V Class 2)

Firetox Flame Retardant Cables

APPLICATION
The cables are designed specifically to suit the broad spectrum of requirements of Variable Speed
Drives and also include features for reducing the transmission of electromagnetic interference.
These range of cables are able to reduce capacitance of power conductors and have an electrically
balanced construction which includes split earths and a copper screen.
This range of screened cables drastically reduce interferences from electrical noise, especially in
Variable Speed Drive (VSD) applications and are manufactured with fixed conductors.
With shield conductivity of 1/10th of phase conductor conductivity, this range of VSD cables
effectively restrain radiated and conducted radio-frequency emissions.

STANDARDS
Basic design to IEC 60502-1
