    • PROBLEM TO BE SOLVED: To reduce the cost of a submarine cable by a satisfactory connection of cables having different conductor section areas.SOLUTION: When power cables 10, 20 having different conductor section areas of central conductors 10a, 20a are mutually connected, and when the mutual central conductors 10a, 20a formed of a plurality of conductor element wires 1, 2 which mutually have different element wire diameters and are concentrically twisted with the same number of layers are connected, the conductor element wires 1 constituting the one central conductor 10a are connected to the conductor element wires 2 constituting the other central conductor 20a, by welding at each concentrically twisted layer. By repeating the above process, a cable connection portion 101, in which the entire conductor element wires are welded, is formed. With this, a submarine cable 100 having satisfactory connection between the power cable 10 and the power cable 20, via the cable connection portion 101 of a flexible joint, is manufactured.
    • 要解决的问题:通过令人满意地连接具有不同导体截面积的电缆来降低海底电缆的成本。 解决方案:当具有中心导体10a,20a的不同导体截面积的电力电缆10,20相互连接时,并且当由多个相互具有不同的导体元件线1,2形成的相互中心导体10a,20a 元件线直径并且以相同数量的层同心地绞合,构成一个中心导体10a的导体元件导线1通过在每个同心扭转层处的焊接连接到构成另一个中心导体20a的导体元件导线2。 通过重复上述过程,形成其中焊接有整个导体元件线的电缆连接部分101。 由此,制造了通过柔性接头的电缆连接部101在电力电缆10和电力电缆20之间具有令人满意的连接的海底电缆100。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a solid cable capable of controlling that the viscosity of an insulating oil impregnated in an insulation layer becomes excessively high.
      SOLUTION: The solid cable 100 has an insulation layer 30 in which an insulating oil is impregnated and at least a part of the insulating layer 30 is constructed by winding around a compound paper having an insulation paper and a plastic layer. This insulation paper is manufactured by going through a pulp manufacturing process and an insulation paper manufacturing process, and in at least one of the pulp manufacturing process and the insulation paper manufacturing process, acid pickling and neutralization treatment are carried out. Then, this neutralization treatment is carried out without using a neutralizer containing metal ions.

    • PROBLEM TO BE SOLVED: To reduce a cable lead-in tension when a submarine cable is installed in a conduit arranged near a submarine cable unloading point and to easily construct the submarine cable in the long conduit. SOLUTION: A tunnel is previously dug near the submarine cable unloading point from land into sea, and the conduit 1 is arranged in the tunnel. When installing the submarine cable 2 into the conduit 1, the submarine cable is pulled out into sea from an installation ship, and a pulling wire connected to the submarine cable is wound up by a winch on land, and the submarine cable 1 is pulled into the conduit 1. A tubular object whose specific gravity is smaller than "1" is fitted to an outermost armour of the submarine cable 2, and cable underwater weight is reduced or set to be neutral buoyancy. Thus, the lead-in tension in unloading is reduced and construction is achieved in the conduit having length with which construction is impossible in a conventional case. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:当海底电缆安装在靠近海底电缆卸载点的导管中时,减小电缆引入张力,并在长导线管中轻松构建海底电缆。 解决方案:隧道预先从海底电缆卸载点附近进入海域,导管1设置在隧道内。 当将海底电缆2安装到导管1中时,海底电缆从安装船被拉出海水,并且连接到海底电缆的牵引线由陆地上的绞盘卷起,将海底电缆1拉入 导管1.比重小于“1”的管状物体安装在海底电缆2的最外层的装甲上,电缆的水下重量减小或设定为中性浮力。 因此,在常规情况下,卸料中的引入张力减小并且在具有长度的导管中实现结构是不可能的。 版权所有(C)2009,JPO&INPIT
