They are supplied with a sealing ring which is stretched over the cable at the inlet to guarantee ‘Ex d’ execution, and a second compression ring which is stretched over the cable armour at the outlet to guarantee an IP 66/68 protection rating, and a metal ring which affixes to the outer surface of the lead sheath as it is wound, fastening it in place. Their structure makes them suitable for environments which are particularly difficult, such as marine environments, or where there are subjected to the mechanical stresses and impacts which often occur in heavy industry, where safety is the utmost priority.
