Cables For Special Applications Lead Sheathed Cables Construction Main constructions are as explained for the various types and voltage grades of medium voltage cables. Lead sheath is applied over an extruded bedding layer. Application The Lead Sheath Cables are suitable for outdoor installations in damp or wet locations, in chemical or petroleum plants, or any hostile environment where protection against hydrocarbons or other aggressive chemical substances is required. Main properties Radially watertight Corrosion resistant Where necessary, it is available with the longitudinal watertight protection Suitable for use in hostile environment or underground Especially suitable for submarine installation Resistant to aggressive chemical substances Offer good protection against rodents Lead sheath acts as an additional metallic screen when needed Low Smoke Halogen Free Cables Construction Main constructions are as explained for the various types and voltage grades of medium voltage cables, except that the cables are specially constructed using low smoke, halogen free materials/compounds. Application The Low Smoke Halogen Free power cables with enhanced characteristics in case of fire are used for applications where harm to human life and damage to property must be prevented in the event of fire, e.g. in industrial installations, commercial establishments, hotels, airports, underground stations, railway stations, hospitals, banks, schools, etc. Main properties Reduced smoke and toxic gases emission in the event of fire Reduced acid gases emission in the event of fire Excellent flame retardant properties 133
