Bergen Cable and the five advantages of pre-formed wire rope

Pre-formed wire rope is available from Bergen.

For the best selection of cable and wire rope, businesses across North America have trusted in Bergen Cable for nearly 80 years. Not only is the company a premier source of cable; it also offers such alternative products as pre-formed wire rope. This comes with its own distinctive advantages.

What makes this wire rope stand out is that its individual wires and strands are pre-formed into a specific shape before it is assembled into its final form.

Resistance to fatigue from bending

Users often talk about “cable” and “wire rope” as if they were synonyms, but wire rope refers to rope that has a diameter greater than 3/8 of an inch, while ropes with smaller diameters are known as cables or cords. The pre-forming process on wire rope eliminates the tendency for wires and strands to straighten by keeping them in their proper positions.

Bergen identifies the five following key benefits of investing in pre-formed wire rope:

• Users can cut pre-formed wire rope without the seizing that is necessary to maintain the structure of standard wire rope.
• The broken rope ends do not untwist, as opposed to the ends of the standard wire rope, and this boosts the salvage value of broken rope.
• This wire rope is substantially free from liveliness and twisting tendencies, making installation and handling easier while reducing the risk of damage to the rope from fouling or kinking. Pre-forming enables more general use of long lay and wire core constructions.
• Removing internal stress boosts resistance to bending fatigue, which expands service in applications that require ability to withstand bending. This also enables the use of rope with larger outer wires when higher wear resistance is necessary.
• Outer wires wear thinner before breakage, whereas broken wire ends do not protrude from rope to injure the user’s hands, nick and distort adjacent wires, or wear sheaves and drums. Since broken ends do not porcupine, they are not as conspicuous as those on standard wire rope. Users need more care during inspection of wore pre-formed rope to determine its condition.
