Tubing Encapsulated Conductor (TEC) is used to supply power downhole to the gauge and transfer the digital data uphole. The copper conductor is double insulated and the protected by a 6.35mm OD stainless steel tube with a wall thickness of 0.71mm. A coating of 11mm x 11mm Polypropylene is used to add additional protect the tube wire.
