Multi-conductor TEC downhole cable is a tubing encased cable for oil and gas wells where a single installation must carry instrumentation data, power, or both. Centralized insulated conductors are cabled together inside a welded and drawn metal tube, with optional encapsulation selected for the well environment.
Key Features
- Designed for downhole gauge data transmission, power delivery, or combined instrumentation and power circuits.
- Centralized double-extruded core with solid or stranded conductor options from 4 AWG to 28 AWG.
- Outer tube options include 316L stainless steel and Alloy 825.
- Optional encapsulation materials include polypropylene, Santoprene, nylon, PVDF, ETFE, ECTFE, FEP, PFA, and ECA 3000.
- Continuous lengths up to 100,000 ft are stated in the source technical data.
Applications
Typical applications include permanent downhole gauges, instrumentation systems, and well installations requiring data transmission, power, or both under demanding temperature and pressure conditions.
