Armouring & reinforcing of cables

Drum twisting line for Milliken Cables and armouring with up to 120 galvanised steel wires ▲ Using tapes and wires

Four types of machine are used for armouring. When armouring with tapes then longitudinal, concentric, or multi-pad tangential taping heads are used. For armouring with galvanised steel wires then either a planetary or cage strander (armouring wires in bobbins), a rigid strander (armouring wires in bobbins) or a drum twister (armouring wires from baskets) is used. Flymca has long experience in building all these machines to meet customer specifications. The company can also construct heavy-duty machinery for the production of cables with very large diameters, as used for submarine and offshore platforms.

Flymca and Flyro are involved in the field of armouring and reinforcing of power cables with many different types of equipment, depending on the purpose. Armouring and reinforcing are used chiefly to protect cables against mechanical damage, such as pulling forces during the laying, or to protect against sharp stones, as well as a support of heavy cables for special purposes. There are two types of armouring mainly used with power and communication cables: tape armouring (when radial stress is expected) and wire armouring (when axial stress is involved). Armouring is provided by either round or flat wires. Flat wires are used to reduce weight and particularly when special armouring is required.
