IEC 60331 Indoor Fire Resistant armoured Telephone Cable
Application
This cable is used for the internal wiring of building when the circuit integrity during fire is paramount. The cable
is intended to take the place of LSZH sheathed cables and will withstand similar environments with a similar
working life. It is intended for use in fire fighting plants with mica tapes, with aluminium foil and LSZH outer
sheath.
