Construction & selection
Single-core copper XLPE cable example with a copper-wire-and-tape screen, LSZH inner and outer sheaths, and aluminium-wire armour. The family designation follows the reference catalogue; exact U0/U(Um), insulation dimensions and project compliance must be confirmed in the current selected datasheet.

Construction
Illustrated variant: CU/XLPE/CWS/LSZH/AWA/LSZH
- Compacted stranded copper conductor
Copper strands are compacted together to form the current-carrying conductor.
- Semiconducting conductor screen
A semiconducting layer around the conductor forms the inner electrical screen.
- XLPE insulation
Cross-linked polyethylene forms the main electrical insulation around the conductor.
- Semiconducting insulation screen
A semiconducting layer around the XLPE insulation forms the outer insulation screen.
- Copper wire and tape screen
Copper wires and copper tape together form the metallic screen around the insulated core.
- LSZH inner sheath
The low-smoke zero-halogen inner sheath separates the screened core from the armour.
- Aluminium wire armour
Aluminium wires form the mechanical armour around the cable.
- LSZH outer sheath
The low-smoke zero-halogen material forms the external protective sheath.

Source notes and standards
- All conductors circular compacted.
- The source line “Equivalent voltage designation as per IEC 60502-2” gives no equivalent value.
- Catalogue states: Cables conform to IEC 60502-2. This is a supplier statement, not independent certification or project approval; edition not stated.
- The cited IEC 60502-2 statement for this 26/35 kV family requires supplier clarification; no compliance claim is adopted here.
