Description
Standards
-
ProductASTM B 230; ICEA S-93-639; UL 1072
Application
Medium Votage single 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 and in underground ducts.
Construction
1. Conductor: Aluminum, compacted class B stranding.
2. Conductor screen: Extruded semiconductive compound.
3. Insulation: Cross-linked polyethylene (XLPE).
4. Insulation screen: Strippable semiconductive compound.
These last three components extruded in CV (continuous vulcanization) of triple extrusion in the dry curing process.
5. Screen: Made up of copper tape.
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.
