Description
- Overall Screen (OS)
- Hydrocarbons resistant
Standards
International : IEC 60332-3-22 Cat.A; IEC 60584-3National : NF C 42-324
Description
Applications
These compensation and extension cables are used with thermocouples for temperature measurements. They are well adapted to underground use in industrial applications where hydrocarbons may be present and mechanical protections are needed (refinery areas, chemical plant…).
Design
Conductor:
Metal in accordance with the thermocouple, either solid of cross-section 0.5 mm² (1 x 0.8 mm), 1.34 mm² (1 x 1.30 mm) or stranded cross-section 1 mm² (14 x 0.30 mm)
Insulation:
Polyvinyl chloride (PVC)
Overall screen:
Polyester tape
Tinned copper drain wire
Aluminium/polyester tape
Inner Sheath:
Polyvinyl chloryde (PVC)
Armour :
Paraffin-waxed crepe paper
Double steel tape
Outer sheath:
Polyvinyl chloride (PVC)
Colour: depends on thermocouple type
Core identification
