What are flexible cables?
Flexible cables are ordinary cable of an electronic city? Everyone may think that it is an ordinary cable or wire , but this is a wrong idea. The main material of flexible cable is composed of mineral compounds. It does not itself cause fire, combustion or support combustion. These materials usually have a melting point of more than 1500, so they are truly fire-resistant flexible cables, which can perform normal power transmission functions even under flame conditions. At the same time, it has unique ductility characteristics. However, many dealers do not buy and do not know what a real flexible cable is. The following small series provides you with some basic purchasing principles, hoping to help you!
Basic principles for selecting flexible cables:
Carrying capacity:
Current carrying is the current value that the wear-resistant cable can bear in use. In general, the carrying current refers to the maximum current value. Therefore, when purchasing wear – resistant cables, it is necessary to check the wear – resistant cables in the structural design Whether to adopt degraded design. For this, as long as it is a regular cable, the product manual will have a detailed description. In addition, it is also necessary to check the insulation value and voltage resistance of the leg of the cable how to see whether it meets the application requirements.
Toughness requirements:
Because the cable is in a dynamic working environment, the conductor of flexible cable must have high requirements for toughness- Generally speaking, the thinner the conductor, the softer the conductor and the better the flexibility. But this is limited because it also requires strong mechanical fatigue strength requirements.
Impedance matching:
Not only flexible cables, but also other types of cables generally have impedance requirements. As long as signal transportation is realized in use, especially in the environment with large magnetic field interference, the requirements for cable impedance matching are more stringent. You should know that if the impedance of the cable is not matched during use, and it is not serious, the signal transmission may be intermittent. If the situation is serious, the signal will be reflected and the signal cannot be received.
Shielding layer:
In order to improve the transmission of cable signals, the shielding layer will be strengthened outside the cable to achieve the shielding effect in the external use environment. In this case, the injection molding method is mainly applied to the flexible cable, and the shielding layer and the inner protective belt are welded to each other. This is detailed in the product specification sheet. Generally speaking, the product performance specifies “shielding function”, “shielding signal”, “shielding layer density”, etc.
The above is a little knowledge about slecting flexible cables. With the in-depth understanding of the cable, you will find how high the requirements of the use environment are, how high the supporting products are, so that it will not be easy to break and the information is not good during the use process.
