The test cable pipeline with high temperature test car, mainly for oil wells parameters test, the downhole instrument cable to provide power, will transfer the downhole signals to the ground acquisition system in instrument, for lifting equipment, due to the special structure of the cable (the whole capillary, which can wear high temperature cable) to seal the wellhead lubricator; the cable such as wear and wire can be used for thermal power, gas injection wells or observation wells monitoring. Due to the special structure of the cable can also be used for other wells direct reading test.
