Abstract:
A plurality of strands (7) of sectorial cross-section is stranded around a central core such as an optical fiber conductor. First, a rigid type stranding machine is used to impart a spiral twist to each strand (7). Then, the twisted strand (7) is heat-treated or otherwise treated to remove any stress caused by the twisting. These strands are then fed to a planetary type stranding machine which provides a planetary motion in which the strands perform an orbital rotation around the optical fiber core of an optical conductor or conductors without rotation about its own axis, whereby the strands are stranded together on the optical fiber core.
Abstract:
A telecommunication submarine cable of co-axial construction has a multistrand centre core imparting tensile strength to the cable, the core having adjacent layers of the core separated by a layer of soft metal.
Abstract:
The making of a closed layer from shaped wires on ropes, cables and similar products in which shaped wires are wound on a rope core and in concurrent plastic squeezing of these wires for redistributing their material and changing their profile so that they become reliably interlocked throughout the entire layer.
Abstract:
Le câble (31) multi-torons à deux couches de torons comprend: -une couche interne (CI) du câble (31) constituée d'un unique toron interne (TI), -une couche externe (CE) du câble (31) compacte et constituée de L>1 torons externes (TE). Chaque toron interne et externe (TI, TE) comprenant une couche interne et une couche externe de fils. La distance interfils D3' des fils de la couche externe de chaque toron externe (TE) est supérieure ou égale à 25 µm.
