Zusammenfassung: | To provide a power cable in which a mechanical support layer is permanently thermally expanded radially as a result of a heat treatment process, thereby mechanically supporting a metallic water blocking layer.SOLUTION: A power cable (1) includes: a conductor (5); an insulation system (7) including an inner semiconducting layer (9) arranged around the conductor (5), an insulation layer (11) arranged around the inner semiconducting layer (9), and an outer semiconducting layer (13) arranged around the insulation layer (11); an elastic mechanical support layer (15) arranged around the outer semiconducting layer (13); and a metallic water blocking layer (17) having a longitudinal weld seam and arranged around the mechanical support layer (15).SELECTED DRAWING: Figure 1
【課題】機械的支持層が、熱処理プロセスの結果として径方向に恒久的に熱膨張し、それによって金属製止水層を機械的に支持する電力ケーブルを提供する。【解決手段】電力ケーブル(1)であって、導体(5)と、導体(5)の周囲に配置される内部半導電体層(9)、内部半導電体層(9)の周囲に配置される絶縁層(11)、および絶縁層(11)の周囲に配置される外部半導電体層(13)を備える絶縁系(7)と、外部半導電体層(13)の周囲に配置される弾性機械的支持層(15)と、長手方向の溶接継ぎ目を有し、機械的支持層(15)の周囲に配置される金属製止水層(17)と、を備える。【選択図】図1 |
