Abstract

SAMMENDRAG Det er beskrevet et system for overføring av elektrisk energi mellom forskjellige deler av en elektrisk ledende struktur, og særlig for overføring av effekt og/eller datasignaler til/fra utstyr eller instrumentering nede i hullet i olje- og gassbrønner. Et første lag elektrisk isolerende, keramisk material (5) avsettes på strukturen (f.eks. en oljerørstreng 3A), etterfulgt av en rekke elektrisk ledende spor (6) og et andre lag elektrisk isolerende, keramisk material (7). Sporene (6) som tjener til å overføre effekt og/eller datasignaler blir således inneklemt mellom lagene (5 og 7), isolert fra strukturen (3A) og det ytre miljø og beskyttet mot skade. Hvert lag (5, 6 og 7) avsettes ved hjelp av en termisk sprøyteprosess, slik som ved plasmasprøyting eller sprøyting med oksygen/brensel ved høy hastighet.
