Description
- XLPE insulation (Part 1)
- Armoured (Type 2)
- Individual & Overall Screen (IOS)
- Hydrocarbons resistant
Standards
International : IEC 60332-3-22 Cat.A; IEC 60584-3Description
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 where chemical and mechanical protections are needed (refinery areas, chemical plant…). The individual screening of each pair limits the consequence of crosstalk.
Design
Conductor:
Metal in accordance with the thermocouple, either solid cross section 0.5 mm² (1 x 0.8 mm), 1.34 mm² (1 x 1.30 mm) or flexible cross-section 1 mm² (14 x 0.30 mm)
Insulation:
Cross-linked polyethylene (XLPE)
Individual screen:
Binder tape
Tinned copper drain wire
Aluminium backed polyester tape
Binder tape
Overall screen:
Binder tape
Tinned copper drain wire
Aluminium backed polyester tape
Bedding (inner sheath) :
Polyvinyl chloride (PVC)
Colour : depends on thermocouple type
Armour:
Galvanized steel wires (SWA)
Outer sheath:
Polyvinyl chloride (PVC)
Colour: depends on thermocouple type
