AFNOR NF M 87-202 IOS Armoured

Applications

These instrumentation and communication cables are used to transmit analogue or digital signals in measurement and process control. They are well adapted to underground use in industrial applications where hydrocarbons may be present and mechanical protection is needed (refinery areas, chemical plant...). The individual screening of each pair limits the consequence of crosstalk.

Nexans code

• 1st serie = number of pairs, triples or quads: 01 to 27
• 2nd serie = pair (IP), triple (IT), quad (IQ)
• 3rd serie = conductor 05 (1 x 0.8 mm), 09 (7 x 0.4 mm) or 15 (7 x 0.52 mm)
• 4th serie = collective screen (EG), individual screen + collective screen (EI)
• 5th serie = mechanical protection: without metal tape (SF), with steel tape (FA), with lead and steel tape (PF)
