HRN HD 620 S1
IEC 60 502-2
XHEh 91, XHEh 91-A
Structure of the cable
- Conductor: Al or Cu stranded wire, compacted
- Conductor screen: Semiconductive layer on the conductor
- Insulation: XLPE
- Insulation screen: Semiconductive layer on the insulation
- Electrical protection/screen: Made of Cu wires, waterproof design
- Sheath: Semiconductive PE
