14.7.6 Coating
Further reading 397
The coating process, used currently for locked-coil cables, consists of coating
the bare wires with an anti-corrosion product with a good bond and long service
life. The various substances used generally have a high dropping point so as not to
run back towards the lower anchorages. They are usually high viscosity resins or
oil-based grease, paraffins or chemical compounds.
14.7.7 Protection of anchorages
The details of the connections between the ducts and the anchorages must prevent
any inflow or accumulation of water. The actual details depend on the type of
anchorages used, on the protective systems for the cables, and on their slope. There
are different arrangements intended to ensure water tightness of vital zones.
14.7.8 Protection against accidents
Cables should be protected against various risks of accident, such as vehicle impact,
fire, explosion and vandalism. Measures to be taken may be based on the following:
(a) protection of the lower part of the stay, over a height of about 2.0 m, by a steel
tube fixed into the deck and fixed into the duct; the tube dimensions (thickness
and diameter) must be adequate.
(b) strength of the lower anchorage against vehicle impact.
(c) replacement of protective elements possible without affecting the cables themselves
and, as far as possible, without interrupting traffic.
