Construction
- Copper or aluminum conductor
- Extruded inner semi-conductor
- Cross-linked PE insulation (XLPE)
- Extruded outer semi-conductor
- Semi-conductive swelling tape
- Metal shielding
- Semi-conductive swelling tape
- Radial sealing (copper or aluminum tape)
- Outer HDPE sheath
Properties
- Longitudinal and radial sealing provided by two layers of tapes that swell in the presence of moisture and prevent the spread of water in case of injury to the sheath
- Special abrasion resistant PE outer jacket with low shrinkage rate
- Cross-linked PE insulation (XLPE) with high dielectric strength and low losses
- Halogen free
