Description

Standards

  • Product
    IEC 60228 Class 2 ; IEC 60502-2

Application

Medium Voltage single core cables are used in electrical energy distribution networks, as feeders for transformers in substations, industrial facilities and urbanizations. They are suitable for installations in dry or wet locations, outdoors, underground ducts or directly buried in earth.

Construction

​1. Conductor: Aluminum, compacted class 2 stranding..

2. Conductor screen: Extruded semiconductive compound.

3. Insulation: Cross-linked Polyethylene (XLPE). 

4. Insulation screen: Strippable semiconductive compund.

These last three components extruded in CV (continuous vulcanization) of triple extrusion in the dry curing process.

5. Screen: Made up of round copper wires with a total cross section equal to twenty-five square milimeter, with a non-hygroscopic separator tape over the wires.

6. Outer jacket: PVC compound, flame retardant, resistant to heat, abrasion and humidity, resistant to sunlight (SR), black color.

RECOMMENDATIONS FOR THE SELECTION OF ACCESSORIES AND DUCTS

The technical information presented here is for reference purposes only. Actual dimensions and construction details will only be available with the test reports for each manufacturing order. For the selection of accessories and/or ducts, it is recommended to measure directly on the actual dimensions of the cable using the appropriate methods and instruments. Centelsa by Nexans will not assume any responsibility for the selection of such elements.
