AFNOR NF M 87-201 pour centrales à énergie fossile

Applications

These compensation and extension cables are used with thermocouples for temperature measurements in fossil power plant . When they are armoured, they are well adapted to underground use in industrial applications where mechanical protections are needed. The individual screening of each pair limits the consequence of crosstalk.

Design

Conductor:

Metal in accordance with the thermocouple, 

- solid cross-section 0.50 mm² (1 x 0.80 mm) or 1.34 mm² (1 x 1.3 mm)
