Lightweight, strong and flexible cables are needed to reliably control the various functions of an aircraft. The production of these “aircraft control cables” is governed by rigid, well-defined specifications (military specification MIL-DTL-83420). In fact, the specifications are so well-defined, that many industrial and commercial users have adopted this as their standard, even for non-aircraft applications.

There is, however, one characteristic that separates aircraft cable from non-aircraft cable — high fatigue resistance. Each aircraft cable must pass a rigorous fatigue resistance test.

Enter Lockclad aircraft control cables, a specialized aircraft control cable consisting of aircraft cable conforming to MIL-DTL-83420 over which is swaged an aluminum tube of proper thickness and length. This combination provides several advantages. It lowers the creep stretch, dampens the vibration of the cable, and provides a higher coefficient of thermal expansion. In addition, the smooth cylindrical surface provides for closer sealing through pressure walls.

The swaged tubing compacts the cable, resulting in an increase in the AE value, which minimizes undesirable stretch characteristics caused by load application. This combination also provides a coefficient of expansion that more nearly synchronizes thermal expansion and contraction of control cables to the airframe of the plane, which results in a noticeable improvement in sensitivity of control.

It’s important to note that the aluminum tubing is swaged only to straight runs of control assemblies. Sections passing around pulleys must be left bare. For this reason, no increase in strength over the bare cable is obtained by the use of Lockclad cables. 

Bergen Cable Technology is one of two companies in the world approved by the U.S. government to manufacture Lockclad cables according to MIL-DTL-87218. The New Jersey-based company is known for innovation, quality products and taking care of its customers. Contact Bergen Cable Technology for more information.
