Abstract

Det omtales en elektrisk flerlederkabel (28) for anvendelse i et underjordisk borehull som omfatter minst en elektrisk leder (30) omgitt av et eller flere lag (32) av isolasjonsmaterial. Minst et lag av isolasjonsmaterialet omfatter etylenpropylen-dienmetylengummi fremstilt ved å anvende en stereoregulær polymerisasjonskatalysator (SEPDM) og/eller polyolefinelastomer fremstilt ved å anvende en stereoregulær polymerisasjonskatalysator (POE). Dette isolasjonsmaterialet har en høyere grad av krystallinitet med en høyere ri ft-holdbarhet og en høyere strekk-hold- barhet og mindre forlengelsestap i forhold til kjente isolasjonsmaterialer, både før og etter å ha vært utsatt for hydrokarboner i underjordiske borehullomgivelser.An electrical multi-conductor cable (28) is used for use in an underground borehole comprising at least one electrical conductor (30) surrounded by one or more layers (32) of insulating material. At least one layer of the insulating material comprises ethylene propylene diene methylene rubber prepared using a stereoregular polymerization catalyst (SEPDM) and / or polyolefin elastomer made using a stereoregular polymerization catalyst (POE). This insulating material has a higher degree of crystallinity with a higher ri ft durability and a higher tensile durability and less elongation loss compared to known insulating materials, both before and after being exposed to hydrocarbons in underground borehole environments.
