The terms are often used interchangeably, but are they different? Each is considered a machine. Wire ropes are usually ⅜” in diameter or larger, while cables or cords are smaller. Though this little distinction exists in aircraft and marine cables, wire ropes and cables are synonymous in most other ways.
What is aircraft cable used for?
Aircraft cables are stranded wires that are used in a wide variety of applications on or around aircraft. They are used as harnesses for electrical wiring as well as tie-downs, stabilizers, safety fasteners, and for many other purposes.
Why is it called aircraft cable?
The term “aircraft cable” is a generic term used to denote wire ropes from sizes roughly . 047” to . 375” and constructions 7×7 and 7×19. … The name aircraft cable is derived from the fact that this style of wire rope is and has historically been used for aircraft flight controls.
What is the difference between Strand and wire rope?
Strands of wire rope consist of two or more wires arranged and twisted in a specific arrangement. The individual strands are then laid in a helical pattern around the core of the rope. Strands made of larger diameter wires are more resistant to abrasion, while strands made of smaller diameter wires are more flexible.
What is the strongest type of wire rope?
Dyneema is the world’s strongest fiber producing ropes that are 15 times stronger than steel wire ropes of the same weight and has become one the most trusted fiber ropes over generic HMPE ropes and steel cable wire ropes for all rigging, maritime, mooring, and towing rope applications.
What are the types of cables used in aircraft?
The most common aircraft cable diameters are 1/16 through 5/32 with 7×7 or 7×19 construction. The most common control cable sizes (depending on strength required) are 7×7 and 7×19 cables. A 7×7 cable consists of six strands of seven wires each, laid around a center strand of seven wires.
How strong is aircraft cable?
Aircraft cable sizes range from 1/32″ to 3/8″, with breaking strengths (tensile strengths) ranging from 120 pounds to 14,400 pounds. Not to be used in any aircraft.
What does 7×19 wire rope mean?
For example, “7×19” means the rope has seven (7) strands, with 19 wires in each strand. 7×19 is the most flexible aircraft cable construction. 7×19 is approximately twice as flexible as 7×7 construction. Aircraft cable is rated by its nominal break strength.
Do aircraft cables rust?
Galvanizing protects the cable from corrosion for a period of time, but will discolor to a white or dull appearance—Prolonged exposure to the elements will eventually cause corrosion, which is why it’s always important to keep your aircraft cable up to date with inspections.
What is metal rope called?
Wire rope is several strands of metal wire twisted into a helix forming a composite rope, in a pattern known as laid rope. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as cable laid.
What is a very strong wire rope?
Answer for the clue “A very strong thick rope made of twisted hemp or steel wire”, 5 letters: cable.
What is the strength of wire rope?
6 strand x 19 wire (6×19) – minimum breaking strength, safe loads and weight
|Rope Diameter||Minimum Breaking Strength|
What is lay in wire rope?
The helix or spiral of the wires and strands in a rope is called the lay. Regular lay denotes rope in which the wires are twisted in one direction, and the strands in the opposite direction to form the rope. … Right or left lay refers to the direction in which the strands rotate around the wire rope.
How do I choose a wire rope?
Following are the most common characteristics to be considered when selecting a rope for an application.
- STRENGTH. Wire rope strength is usually measured in tons of 2,000 lbs. …
- FATIGUE RESISTANCE. …
- CRUSHING RESISTANCE. …
- RESISTANCE TO METAL LOSS AND DEFORMATION. …
- RESISTANCE TO ROTATION.

How do you calculate SWL of wire rope?
To calculate the SWL in kilograms of FSWR square the rope diameter (D) in millimetres (mm) and multiply by 8.
- Formula: SWL (kg) = D2(mm) x 8.
- Formula: D(mm) = √L(kg)
How much weight can a 5/16 cable hold?

|Breaking Strength:||9,800 lbs|
|Working Load Limit (5:1) Design Factor:||1,960 lbs|
|Weight per foot:||0.173 lbs|
|Corrosion Resistance:||2/5 Stars|
