How you can Select a Wire Or Cable

For anyone who is about to buy wire or cable for the very first time, or perhaps in case you have bought it in the previous, you could possibly locate the activity daunting. Right after all, most distributors stock a huge number of wire and cable products. Your application may possibly call for ribbon cable, but which certain ribbon cable really should you buy? Having possibilities is significant, but with numerous alternatives, decision-making can develop into overwhelming. Get extra facts about  สายคอนโทรล 

Do you know what concerns to ask? Just before starting a search, equip oneself with all the proper expertise. Background data combined with standard preparation can give you some command through the buying process. In the post, "Specifying High-Performance Cables: The Devil Is Within the Details," by Alpha Wire Company, they evaluate 4 primary concerns to be deemed. They are cable shielding, flexibility, chemical resistance, and temperature range.


When acquiring cable, be sure you explore cable shielding. Shielding ensures that the electrical process runs smoothly. An engineer will let you know shielding minimizes issues of signal exit or entrance triggered by interference. Types supplied consist of braid, foil, spiral, or perhaps a mixture braid/foil shield. Each variety has advantages and disadvantages:

Foil Shields:

Uses: CATV, MATV, Video, computer I/O cables

Positive aspects: 100% cable coverage, low weight and low price

Disadvantages: Higher DC resistance and reduced mechanical strength

Braid Shields:

Uses: Computers to terminate interconnect for process or control applications

Benefits: Fantastic structural integrity, flexibility and flex life Disadvantages: Does not deliver complete coverage, heavy

Spiral Shield:

Uses: Microphone, audio cables and retractile cords

Advantages: Great flexibility and flex life

Disadvantages: Not helpful above audio frequency variety

Combination Shields:

Uses: Video, CATV, MATV, networking, laptop I/O cables

Positive aspects: 100% foil coverage, powerful and low resistance

Disadvantages: Higher price than other shields

Chemical Resistance

An engineer will inform you that electrical cables possess various levels of chemical resistance, but there may very well be a lot more to it. You should know which chemical compounds could present a possible trouble in the entire lifespan of one's cable. Also, take into account that oils and corrosive chemical vapors or liquids could potentially enter into the cable connections. Any type of chemical intrusion could result in cable failure. You could want to add further sealing to prevent moisture permeation.


Temperature variety is an additional important issue inside the mix of things. What temperatures will your cable have to have to withstand to become helpful? You could possibly discover that a cable possesses all of the needed electrical functions required for intense temperatures, but will it have the ability to adapt to the physical demands linked with that temperature?

Flexibility and Flex

A flexible cable can make installation and troubleshooting a great deal much easier. Nevertheless, did you realize that "flexing" is actually a distinctive problem that needs to become addressed? As a result of nature of many manufacturing applications, cables may perhaps encounter continual flexing. Unique cables are constructed much better for this than other people.


There is extra to obtaining the perfect cable than meets the eye. Don't be intimidated by options. A cable exists for just about every environment and application in case you know what to look for. Invest some time asking the appropriate questions and look at every angle.
