AFNOR NF M 87-202 OS Lead Covered 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, in moist areas, where hydrocarbon and mechanical protection are needed. The lead cover brings an enhanced resistance to aromatics hydrocarbons.

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 = overall screen (EG), individual screen + overall screen (EI)
• 5th serie = mechanical protection: without metal tape (SF), with steel tape (FA), with lead and steel tape (PF)
