RG7H1OR EPR Insulated Medium Voltage Power Cable
TEBAOFLEX RG7H1OR is a three-core medium-voltage power cable for fixed industrial and infrastructure installations. It combines Class 2 tinned copper conductors, G7 EPR insulation, copper-tape screening and a red PVC outer sheath in a construction referenced to IEC 60502-2.
The listed design is available across multiple voltage classes from 1.8/3 kV to 18/30 kV. Select the final voltage class, conductor size, installation method and any mechanical protection requirement according to the project specification.
Construction
- Conductor: Class 2 tinned copper, compact stranded construction.
- Insulation: G7 EPR rubber compound with extruded inner and outer semi-conductive layers.
- Screen: copper tape screen around each insulated core.
- Filler: flame-retardant compound.
- Outer sheath: red PVC, ST2 grade.

Current ratings depend on installation conditions. The listed buried ratings use the referenced ground thermal resistivity condition; confirm site conditions before final cable selection.
Typical Applications
- Medium-voltage distribution in industrial facilities
- Substation and transformer connections
- Fixed cable routes in commercial and infrastructure projects
- Projects requiring a screened three-core EPR-insulated cable with a red PVC sheath
Selection Checklist
- Confirm the required Uo/U voltage class.
- Identify the conductor cross-section and installation method.
- Check current-carrying requirements against actual ambient and soil conditions.
- Specify any additional protection, such as steel tape armour, if required by the project.
