General terms
1. Conductor
2. Insulation
3. Filler
4. Binder tape
5. Inner sheath
6. Armor
7. Outer sheath
The cable design
Functionalized inner sheath
• Purpose
• The functionalized inner sheath aims to complete the cable protections with additional resistance
to fluid & chemicals
• Risk of penetration of chemical products (acids, bases, aliphatic and aromatic hydrocarbons)
towards the conductors,
• 2 technologies have to be considered as lead covering or HYPRON® technology from Nexans
General properties of functionalized inner sheath
Water & moisture protection
HYPRON® Aliphatic hydrocarbons protection
Aromatic hydrocarbons protection
Chemicals protection
A Nexans technology for aliphatic and aromatic hydrocarbons resistance
Lead covering
European regulation context
• Tougher and strongest regulations in Europe (REACh & RoHS):
– REACh: Registration, Evaluation, Authorization of Chemicals (1907/2006/EU Directive)
– RoHS: Reduction of Hazardous Substances (linked with WEEE) (2002/95/EU Directive, amended in
2011/65/EU Directive)
• Trend to ban or limit the use of lead components in cables
• Taking into account exposure of workers to these components
– Lead stabilizers in PVC Compounds
– Lead chromate pigments in coloured masterbatches
Lead as metal ?
“Our target has been to develop a new chemical barrier, safer to the person & to the environment”
Sustainable Development
Early development steps
« Sustainable development is development that meets the needs of the present
without compromising the ability of future generations to meet their own needs. »
Definition was established during the World commission on Environment and Development (WCED).

HYPRON® a Nexans technology
Global presentation
• As a optimized safety alternative to lead sheath, Nexans has developed a
new barrier for petrochemical environment, protecting against chemical &
petrochemical fluids
• HYPRON® technology is designed by construction of Aluminium tape
bonded with a co-extruded special chemical resistance polymer layer
Aluminium coated tape
sealed barrier against moisture and inorganic chemicals ingress
Special Chemical Resistance Polymer
co-extruded layer applied over the tape against organic chemicals ingress
HYPRON® a Nexans technology
Resistance table & representative chemicals
HYPRON® is complying with
Lead sheathing is also sensitive to multilayer performance protection
Oxidative areas equivalent to lead protection
Hydrogenated and peroxide areas as per EN 50288-7
