Description
- Lead free
- Armoured with galvanized steel wires (SWA) or aluminium wires (AWA)
- Aliphatic and aromatic hydrocarbons resistant.
Standards
International : IEC 60228; IEC 60332-3-22 Cat.A; IEC 60502-2Description
Applications
These power cables are used for electricity supply in medium voltage installation system. They are well adapted to underground use in industrial applications, in moist areas, where hydrocarbons and mechanical protections are needed. Hypron® offers an alternative to conventional lead covered cable and is an environmental friendly solution.
