Description
- Overall Screen (OS)
- With lead cover (LC)
- Aliphatic and aromatic 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, in moist areas, where chemical and mechanical protections are needed. The lead cover brings an enhanced resistance to aromatics hydrocarbons.
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)
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
Lead cover
