Product Overview
The 01181371 TEC (Tubing Encapsulated Cable) is a high-integrity downhole electrical cable engineered for long-term deployment in oil & gas wells. Designed with 316L stainless steel tubing, 18 AWG tin-coated copper conductors, and polypropylene encapsulation, this cable is optimized for electronic sensing systems, including pressure and temperature gauges in challenging reservoir environments.
Manufactured by Rockbestos, this TEC provides excellent mechanical strength, thermal resistance up to 150°C, and chemical durability for extended field life in reservoir monitoring and permanent downhole sensing systems.

Frequently Asked Questions (FAQ)
Q: Can this cable withstand H₂S service environments?
A: Yes, 316L tubing and fluoropolymer insulation provide chemical resistance suitable for sour service. NACE documentation available.
Q: Is this cable armored or pressure-rated?
A: Yes, 316L tubing with 0.028" wall offers excellent pressure containment in standard TEC applications.
Q: Can I use this in multi-drop gauge installations?
A: Absolutely – it supports multiple gauge strings and has the structural resilience for multi-drop monitoring systems.
Q: Can this be spliced or repaired in the field?
A: Field splicing is not recommended. Pre-measured, connectorized assemblies or full-length replacements are advised.
