XLPE or EPR 5, 8, 15, 25 and 35 kV Medium Tension

90 °C

General description

Single-conductor cable manufactured with one soft copper or hard 1350 alloy aluminum conductor with semi-conducting shield and cross-linked polyethylene (XLPE) or Ethylene Propylene Rubber (EPR) insulation, extruded shield over insulation, metallic copper stranded shield, and polyvinyl chloride (PVC) jacket.

Specifications

  • Viakons shielded and jacketed XLPE or EPR medium voltage cables meet the following specification:
  • NMX-J-142 Single Conductor Power Cables from 5 kV to 115 kV.

Main applications

  • Underground primary distribution networks in commercial areas with a very high load density.
  • Primary electrical energy supply and distribution in industrial plants.
  • Primary distribution networks in residential areas.
  • Electrical power supply and distribution for buildings with substations located on different levels.
  • Can be installed in conduits and ducts.

Characteristics

  • Maximum operation voltage: 5 000, 8 000, 15 000, 25 000 or 35 000 V.
  • Insulation levels from 100% to 133% (categories I and II respectively).
  • Maximum operation temperature: 90°C.
  • Maximum operation temperature in an emergency: 130°C.
  • Maximum operation temperature in a short circuit: 250°C.
  • Soft copper or hard 1350 alloy aluminum conductors with compressed concentric strands in sizes from 8,367 to 506,7 mm 2 (8 AWG to 1 000 kcmil).
  • The insulation can be cross-linked polyethylene (XLPE) or ethylene propylene (EPR)
  • The metallic shield is manufactured with copper strands size 0,324 mm 2 (22 AWG) that meet the NMX-J-142 and NRF-024-CFE requirements.
  • The polyvinyl chloride (PVC) jacket has no-flame propagation characteristic.
  • Red jacket.

Advantages

  • Metallic shield:
  • Provides an excellent ground connection, which improves personal safety conditions during the operation of the cable.
  • Confines and equalizes the electrostatic field.
  • Protects operating equipment from electrical failures
  • Jacket provides mechanical protection against abrasion and mal-treatment during installation.
  • Anti-flame jacket makes them resistant to weather, sunlight, and chemical agents.
  • Suitable for direct burial.
  • Excellent electrical and mechanical characteristics.
  • Can be installed in conduit and ducts.
