Abstract
Det omtales en elektrisk flerlederkabel (28) for an- vendelse i et underjordisk borehull med en forbedret motstand mot svelling forårsaket av absorpsjon av skadelige fluider. Kabelen (28) omfatter et antall elektriske ledere (32); at minst ett lag (34) av et isolasjonsmateriale omgir antallet elektriske ledere; en kappe (36) av et elasto- merisk materiale omgir de isolerte elektriske lederne; en fluidsperre (38) omgir kappen; og en ytre armering (40) omgir fluidsperren. Fluidsperren (38) motvirker at hydro- karboner og vann absorberes inn i kappen (36) av elasto- merisk materiale, som derved forhindrer svelling av kabelen. Den ytre armeringen (40) kan omfatte et belegg (44) av termoset og/eller termoplastisk materiale som forhindrer korrosjon på kabelens armering, for bedre å forhindre en svelling av kabelen.
