IEC 60502-2 Armoured (LC-SWA) Fire retardant

Description

Description

Standards

  • International
    IEC 60228; IEC 60332-3-22 Cat.A; IEC 60502-2

Applications

These power cables are used for electricity supply in medium voltage installation system. They are well adapted to underground use in industrial applications, in moist areas, where hydrocarbon and mechanical protections are needed. The lead cover brings an enhanced resistance to aromatic hydrocarbons.

 

Design

Conductor:

Stranded bare copper (class 2)

Semi conductor

Insulation:

Cross-linked polyethylene (XLPE)

Semi conductor

Screen:

Copper tape

Bedding (optional):

An inner sheath acting as a filler with practically zero thickness

Inner sheath:

Polyvinyl chloride (PVC)

Lead cover (lead sheath)

Bedding sheath (intermediate sheath):

Polyvinyl chloride (PVC).

Armour:

Galvanized steel wires (SWA) or aluminium wires (AWA) for 1 core cable

Outer sheath:

Polyvinyl chloride (PVC). Colour: red. Other colour on request

 

Core identification

1 core: natural
3x: black - green - brown (by tape under copper screen). 
 

 

Marking

NEXANS 279 XLPE/PVC/LC/PVC/SWA or AWA/PVC VOLTAGE Nber of cores and cross-section Cu/Alu IEC 60332-3-22(A) MM YYYY Manufacturing number + metric marking.
