1/4" TEC Downhole Cable with Bumper Wires for Oil Well Sensor
Product Description
Rectangle Tubing Encapsulated Downhole Sensor Cables With Bumper Wires
Applications
The ENGELEC downhole cable for sensor application. It is designed to perform in the well and withstand elevated temperatures, high pressure and corrosive environments. It is used in conjunction and connecting with a big range of permanently installed electronic downhole pressure sensor,temperature sensor or other electronic equipment. The downhole cable is targeted to < 150°C offshore and land-based wells where ruggedness is essential.
