Long Life Cable

When you are looking for a control cable, ruggedly constructed cables mean long life cables. There are many different manufacturers producing control cables for outboard engines, and many different manufacturing techniques. Depending on how the interior of a cable is produced, the cable may be suitable for different kinds of applications, and may be a long life cable.

Common Long Life Cable Designs

There are a handful of different long life cable design techniques. The simplest design is a design involving a wire rope core. It is commonly used for applications that involve a spring return, due to its inability to "push" heavy loads. Solid core cables are slightly more complicated, and slightly stronger than wire rope core cables. Solid core cables, however, are limited in applications that involve tight bends in the cable's route.

Armored core cable design is slightly more versatile than solid core design. Armored core cables feature a soft wire rope interior that is wrapped by a thin metal ribbon. They are both flexible and strong, but they will stiffen under the strain of multiple turns. Coated wire rope long life cables, are similar to armored core cables except that they use plastic instead of a metal sheathing.

Helically wound wire rope core cables are used in heavy-duty applications that need stronger push-pull ability. The core of the wire is helically wound, and engages teeth in a helm to move the core back and forth. Under a load and through turns, helically wound wire rope core cables generally perform better than either armored core or coated wire rope cables.
