EN 50288-7 XLPE Insulation OS Armoured 30x2x1

Description

Description

Standards

  • Test
    IEC 60332-3-22 Cat.A

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:

Metals in accordance with the thermocouple, either solid cross section 0.5 mm² (1 x 0.8 mm), 1.34 mm² (1 x 1.3 mm) or flexible of 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:

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
