Description
Standards
-
NationalASTM B 496; ASTM B 8; ICEA S-93-639; UL 1072
Application
MV monopolar cables are used in medium voltage 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: Compacted soft copper, class B.
2. Internal semi-conductor: Extruded compound.
3. Insulation: Cross-linked polyethylene XLPE.
(Optional): XLPE-TR (Tree retardant).
4. External semi-conductor: Peelable extruded compound.
These last three components extruded in CV (continuous vulcanization) of tripleextrusion in the dry curing process.
5. Screen: Copper Tape.
6. Outer cover: Anti-flame PVC compound.
