TRATOS® XLPE/XLPE
Cathodic Protection Cable
Cross-linked Polyethylene (XLPE) insulated, Cross-linked Polyethylene (XLPE) sheathed, single core cable.
Tratos single core XLPE/XLPE unarmoured cable is designed for use as a high electrical performance connecting cable in cathodic protection systems worldwide.
Because of its many benefits, Cross-linked polythene (XLPE) is now used almost universally as insulation on LV cables. Polyethylene, which is thermoplastic, is transformed into an elastomeric material (XLPE) by cross-linking, which Tratos accomplished by chemical methods. Tratos cross-linked polythene has good mechanical properties and good resistance to abrasion coupled with excellent dielectric properties. Because of its elastomeric nature, it withstands high temperatures without melting or excessively deforming. XLPE has higher modulus and strength at elevated temperatures than HDPE it also has reduced creep and sensitivity to stress cracking. The resistance of XLPE to water is excellent, to chemicals and solvents generally good, but it has rather poor resistance to mineral and vegetable oils. Standard XLPE compounds are not flame retardant, however, they are classed as halogen-free.
Immediately over the inner layer of XLPE, Tratos extrude a second thicker layer of XLPE. This second layer of XLPE gives enhanced electrical performance and has higher modulus and strength at elevated temperatures compared to an HDPE sheath, it also has reduced creep and sensitivity to stress cracking. Performance when subject to water and chemicals is also better than PVC sheathed cables.
Tratos XLPE/PVC cables offer enhanced performance and reliability over an extended lifetime in most cathodic protection applications, including permanent or prolonged periods of immersion in water.

Application
Tratos Cathodic Protection Cables are single conductor cables that are intended to carry a DC current to anodes and cathodes in a cathodic protection system. Tratos Cathodic Protection Cables are designed for use in both active and passive cathodic protection systems to eliminate and prevent corrosion in Metals. Tratos Cathodic Protection Cables are used to eliminate and prevention the corrosion of steel pipelines and steel storage tanks, offshore oil and gas installations, offshore wind farms, ships and other maritime applications installed in air or water. Tratos XLPE/XLPE Cathodic Protection Cables are intended for installation in applications where there is a risk of medium mechanical damage and better water and chemical resistance than a PVC sheath is required.Specifications
