Document Type and Number:
Japanese Patent JP6659829
Kind Code:
B2
Abstract:
The present invention relates to a power transmission cable (10; 20; 30) and a process for the production of the cable, which comprises a metal conductor (1; 21; 31), an electric insulation system (2; 22; 32) and a protection system surrounding the insulation system. The insulation system (2; 22; 32) comprises an inner semi-conducting layer (4; 24; 34) surrounded coaxially and radially outwards by an insulation layer (5; 25; 35), and the insulation layer is optionally surrounded coaxially and radially outwards by an outer semi-conducting layer (26; 36). The protection system comprises a moisture barrier arrangement (3; 23; 33) surrounding the insulation system coaxially and radially outwards of the insulation system. The moisture barrier arrangement (3; 23; 33) comprises an independently applicable first layer (7; 27; 37) and an independently applicable second layer (8; 28; 38), the first layer (7; 27; 37) being an extruded plastic material layer and arranged in direct contact with the insulation system (2; 22; 32), and the second layer (8; 28; 38) being a metallic material layer and arranged in contact with the first layer (7; 27; 37).
