Description
The Permanent Downhole Cable provides a mechanism to communicate to the downhole gauge, providing power and telemetry to and from the sensor. The standard format is 0.25” OD, 316SS TEC protected by 11mm x 11mm Fluoropolymer encapsulation that provides a high degree of protection for the mono-conductor line. This TEC is 150°C (302°F) rated with 7 strand conductor line. These cables are manufactured under ISO quality control and are fully tested with all relevant documentation available.
