What to Keep in Mind Before Selecting Cable or Wire

02.09.2009 | Author: calmontcalifornia | Posted in Technology

Sometimes there comes a occasion when we have to select or buy something about which we hardly know anything. Purchasing a wire or cable for your home or work is a work like that and can become a daunting task for most of us. After all, our markets are full of products like these and most dealers’ stock wires of different sizes, length, thickness, and colour but how do we know which one is the best for us?

The best way to start your hunt of buying a perfect custom cable is to consult a friend, neighbour, colleague or family member who has some knowledge about the hardware. They may not be able to accompany you because of their routines but can definitely give you few practical tips that will help you in taking a correct decision.

Cable Shielding is one of the main points to consider during the purchase. Shielding is what ensures that the electric current flows through the cable smoothly without any danger. It also minimizes the issue of signal exit or entrance that can be caused by interference. There are mainly four types of shielding – foil, braid, spiral and combination of braid and foil.

A green cable with foil shield ensures that it is covered till the end and is generally cheaper that the other types of cables. Braids shields are majorly used in computers to terminate inter connections for controlling different applications. Its advantages include flexibility and longer structural integrity.

Cables with spiral shield are normally used for microphone, and audio cables. These also offer greater flexibility and longer shelve life. Combination shields come with total foil coverage and are strong but the disadvantage includes higher costs.

You can also go for Robotics cable, which can work without any problem within a temperature range of -40 to +80°C and ensure continuous twisting motion for flexing applications. Coaxial cable is another option if looking for electrical cable with an inner conductor and surrounded by an insulating layer.
