Fire Resistant Instrumentation/Data Cables

Suitable for petrochemical industry, this cable is designed to connect electrical instruments circuits and provide communication services in and around process plants. These cables are essential to maintain circuit integrity when exposed to fire and where life may be endangered by smoke & noxious fumes and where sensitive equipment may be damaged by acid forming gases.

Generally in accordance with BS 5308, but with the addition of fire properties relevant to IEC 60331.

Conductor: Stranded (class2) copper conductors to BS 6360.

Insulation: Mica/glass tape, XPLE, FRZN

Pairs/Triplets Identification: These cables are colours coded in accordance with BS 5308 part2.

Tape: Mylar tape with overlap

Collective Screen: Tinned copper drain wire(s) under and in contact with Aluminium Mylar tape applied metallic side down.

Inner Sheath: FRZH

Armour: Mild galvanised steel wires/Flat strip

Outer Sheath: FRZH

Fire Characteristics: Fire resistant to IEC 60331 (750°C for 3 hours)

Temperature Rating: 80°C maximum conductor operating temperature.

Voltage Rating: 300/500volts
