Thermocouple EN 50288-7 PVC Insulation OS Armoured Fire retardant
Description
- Thermocouple cables 170/300 V
- Overall Screen (OS)
- Hydrocarbons resistant
Description
- Overall Screen (OS)
- Hydrocarbons resistant
Standards
International : IEC 60332-3-22 Cat.ADescription
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…).
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:
Polyvinyl chloride (PVC)
Overall screen:
Binder tape
Tinned copper drain wire
Aluminium backed polyester tape
Bedding (inner sheath):
Polyvinyl chloride (PVC)
Colour : black or depends on thermocouple type
Armour:
Galvanized steel wires (SWA)
Outer sheath:
Polyvinyl chloride (PVC)
Colour: depends on thermocouple type
