Cables
A cable is a set of wires wrapped around a central wire, sometimes only virtually, to form a new highly resistant but flexible element for different purposes, but especially to support or pull other items, also very heavy.
ROP STEEL CABLE
A cable is a set of wires wrapped around a central wire, sometimes only virtually, to form a new highly resistant but flexible element for different purposes, but especially to support or pull other items, also very heavy.
In our case, cables are used to connect pile to anchor in systems with rear anchoring.
Ultra-resistant steel wires with high carbon content (min. 0,6 %) are used to provide material with high resistance and low elongation rate. In this way, anchoring system can be connected to the pile in a stable way and without extensive maintenance works.
Cables, formed by intertwining wires, are highly flexible and easily adjustable to anchored parts.
Wires quantity depends on cable intended purpose and, consequently, desired resistance. Generally, steel cables with 19-intertwined wires are used to guarantee high strength and sufficient flexibility, preventing wires from breaking and consequently unravelling, as happens with cables with a significant amount of wires (49 or 116).
Wires constituting the cable are normally hot-galvanized and may have different levels of galvanization thicknesses.
Amount of zinc applied to wires defines cable protection class and, consequently, its likely duration over time.
