Abstract (en)
[origin: WO2019224452A1] The invention relates to the field of cables for an offshore environment (known as "downhole cables"). More particularly, the invention relates to an electrical cable having an insulating multilayer structure based on fluorinated polymers and polyolefins. This structure is made up of multiple layers that are intercohesive and obtained by coextrusion. The invention also relates to the use of said cable as a drilling material for extracting petroleum or natural gas.
