AFNOR NF M 87-202 pour centrales à énergie fossile

Applications

These instrumentation and communication cables are used to transmit analogue or digital signals in measurement and process control in fossil power plant. When they are armoured, they are well adapted to underground use in industrial applications where mechanical protection is needed  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)
