Claims (10)
1. Elektrisk starkströmkabel som är motständskraftig mot bildande av "vattenträd" i isoleringen, innefattande en ledare försedd med ett eller flera skikt extruderat polymert isolerings-material sarat ett inre och ett yttre halvledande skikt och ett yttre skyddsskikt av polymermaterial, kännetecknad därav, att utanpä och avskilt frän isoleringen är anordnat ett sammanhängande skikt som innehäller vattenlösliga salter, vilka förblir vattenlösliga under kabelns livstid och vilka pä i och för sig känt sätt begränsar och stabiliserar den relativa fuktigheten i ledarisoleringen till ett värde som ej överskrider 70%.
2. Starkströmkabel enligt patentkravet 1, kännetecknad därav, att salterna väljes ur gruppen salter som bildar stabila hydrater.
3. Starkströmkabel enligt patentkravet 2, kännetecknad därav, att det vattenlösliga saltet är CaC^·
4. Starkströmkabel enligt patentkravet 2, kännetecknad därav, att det vattenlösliga saltet är MgC^·
5. Starkströmkabel enligt nägot av de föregäende patent-kraven, kännetecknad därav, att de vattenlösliga salterna innehälles i det halvledande skiktet.
6. Starkströmkabel enligt nägot av de föregäende patent-kraven, kännetecknad därav, att de vattenlösliga salterna innehälles i ett spiralformigt lindat band.
7. Starkströmkabel enligt nägot av de föregäende patent- kraven, kännetecknad därav, att mängden vattenlösliga 2 salter är minst 0,01 g/cm av skiktets yta.
8. Förfarande att framställa elektrisk starkströmkabel enligt patenkravet 1, varvid en elektrisk ledare förs genom ett eller flera extrudermunstycken för päföring av ett inre halvledande skikt, ett eller flera isolerande skikt och ett yttre halvledande skikt, varvid minst ett av skikten bestär av tvärbundet polymert material, varefter kabeln genomgär en tvärbindningsprocess sä att ett eller flera av de nämnda skikten tvärbindes, samt päföres ett yttre skyddsskikt av polymermateria], kännetecknat därav, att kabeln utanpä och avskilt frän isoleringen, genom lindning,
