Applications
- Underground distribution networks
- Pipe laying and ground laying
- Installation in electrical substations
Construction
- Round copper or aluminium conductor
- Extruded inner conductor
- Cross-linked PE insulation (XLPE)
- Extruded outer semi-conductor
- Semi-conductive swelling tape
- Laminated aluminium tape screen
- Black PE outer sheath, with 2 red longitudinal stripes
- Three-pole construction:
- Assembly of three monopolar cables
- Outer sheath in HDPE
Properties
- Longitudinal sealing by two layers of tape which swell in the presence of moisture and prevent the spread of water in the event of an injury to the sheath
- Radial sealing provided by the laminated aluminium tape
- Special abrasion resistant PE outer jacket with low shrinkage rate
- Cross-linked PE insulation (XLPE) with high dielectric strength and low losses
- Halogen free
