Description

Standards

  • International
    IEC 60332-1; IEC 60502-1
  • National
    EEMUA Pub. N°133

Application


These power cables are used for electricity supply in low voltage installation systems.

They are well adapted to underground use in industrial applications where chemical and mechanical protections are needed (refinery areas, chemical plant…)

 

Design

 

  1. Conductor
    Stranded bare copper class 2 acc. to IEC 60228
     
  2. Insulation
    Cross Linked Polyethylene "XLPE"
     
  3. Inner Sheath or Bedding
    Lapped bedding or extruded PVC 
     
  4. Metalic Sheath 
    Extruded Lead sheath layer
     
  5. Armour
    Galvanized Steel Wire Armour "SWA"
  1. Outer Sheath 
    Polyvinyl Chloride "PVC"

      Options :

             - Flame retardant : "CAT A, CAT B, CAT C" to IEC60332 or equivalent.

             - Ozone resistant.

             - Oil resistant.

             - Anti termite.

 Installation Conditions:

  1. Air Temperature : 30 Deg.
  2. Ground Temperature: 20 Deg.
  3. Soil Thermal Resistivity : 2.5 k.m/w
  4. Depth of lay : 0.7 m

 All dimensions have tolerance +- 7 %
