What is flexible armored cable?
The flexible armored cable is a regular connection with an extra layer of security to prevent cutting or destruction. The cable core's efficiency, reliability, and security are all improved due to the armor. Flexible armored cable wiring is commonly used in situations that need bending regularly.
What are the different types of flexible cords?
How many types of Flexible Cable are there? There are four common types of cable flexing movements. These include rolling flex, bending flex or "tic-toc," torsional flex, and variable/random motion flex. These cables are meant for repetitive motions.
What are the components of flexible armored cable?
It is usually made of interlocking or continuous aluminum or stainless steel, or it can be covered in a smooth or corrugated metal tape. According to Mencom, which uses a stainless-steel design, the armor protects the cable inside from water damage by high-pressure washdown, cleaning agents and extreme temperatures.

What is a flexible cord?
Flexible cords and cables are used to connect electrical equipment to a power source. Flexible cords may have an electrical plug that connects to a power source or they may be permanently wired into a power source. Extension cords (cord sets), cables, and electrical cords are types of flexible cords.
How many cycles are in continuous flex cables?
Cables that are used in continuous flex applications are tested for use between 1 and 20 million flex cycles. This large range means that, once again, you should check the manufacturer’s testing conditions to determine what they mean by the cables being rated for “continuous flex” applications such as moving robotics, continuously moving gantries, etc. For example, LAPP has a very specific cable motion classification, where the cycle life range, description of movement type, and a motion “level” are assigned as an easy way to determine what type of cable would be best suited for your application. Applications for continuous flex cables range from rolling flex applications like in cable track installations to bending flex applications where the cable is continuously moving but in a more variable or random fashion, as these applications are usually not automated.
Why is it important to know what type of cable is under motion stress?
Though terminology and testing standards are not uniform across all manufacturers, knowing which type of motion stress your cable will be under is important in order to choose a cable with the correct level of bendability and flex life. It could save you a lot of time, money, and headache in the future.
Do you need to flex a cable around corners?
Stationary cables are a very common and cost-effective solution, but you must be sure that the cable will not need to be routed around corners during installation, and that no bending or flexing of any kind will be required.
Is cable flexible?
When looking to spec in a cable that will work for your application, the cable’s degree of flexibility is an important and often overlooked, factor to consider. Some cables are physically flexible, which can ease routing concerns during installation, but other cables are actually designed to be installed in flexing applications with different types ...
Is there a scale for cable flexibility?
There is no official, acknowledged scale or terminology to define different types of cable flexibility, but below we detail the most standard cable flex types and the applications where each is the best option.
Can flexible cable be moved constantly?
In applications where a flexible cable would be appropriate, usually, one end of the cable is stationary and the other moves. In an application like this, the cables are not moved constantly. Typically, these cables are not tested to withstand any number of flex cycles, but some manufacturers claim to have tested their flexible cables up to 1 ...
What is armoured cable?
