Choosing the Best Electric Wires and Cables for Your Home

Choosing the Best Electric Wires and Cables for Your Home

Test and measuring equipments do not find their application in the laboratories only. One such counterparts of them is the Electric and electronic test accessories. This segments includes Connectors, cables, and accessories for electrical and electronic testing are included in the electrical and electronic test accessories. Following are some of the basic types and tips that one should remember while purchasing these wires and cables for their homes or any other purpose.

If one is planning to indulge in the electrical work at home, he or she should be very clear regarding the types of conductors to be installed. Options of combination of single conductors or a multi conductor cable are available. Today the trend of using cable has become a rage as wires and wiring technique have their applications restricted to single conductors only. Single conductors come in two variants - THW and type THWN/THHN which are suitable for both dry as well as wet locations for temperatures up to 75 degrees Centigrade. Most of these wires and cables come inside protective metal or plastic conduit and one can buy either solid-core or stranded wire. While solid core wires are stiffer and thus difficult to snake through, they have the advantage of having better connectivity.

The variety of cables present in the test and measurement equipments industry is also wide. Cables are are typically referred to the combination of neutral wire, one or two hot wires, and a grounding wire inside a plastic or metal covering. Lest have a brief look on some of the types of cable available in the measurement and test equipments market.

Non Metallic Sheath Cables – These are widely used for interior projects and is sold by the foot or in boxes that house from 25 to 250 feet of coiled cable. They are suited only for dry locations and can withstand temperature up to 60 degree Centigrade.

Armoured Cables – These power cables are designed for the supply of mains electricity. They are mostly found in underground systems, power networks and cable ducting and can be used only on multicore versions of the cable.

Besides the above mentioned there is MC types of cables that too are used for indoor applications but are relatively more expensive.
In addition to the types, cables are bifurcated as per their sizes and the number of containers they contain. For example, any cable that contains one neutral and one hot wire is referred as two wire cable. The diameter of the cables is also considered. The larger the wire's diameter, the larger its current carrying capacity, or ampacity, and the lower its gauge number. One can find these numbers on the cable sheathings. The most important tip however is that if you're considering one of these wires, first check your local electrical codes.

Transferring Technology – Avionics Grade Wire and Cable

Transferring Technology – Avionics Grade Wire and Cable

Doing more with less is the catchword of wires and cables that are one of the most important component in the electrical electronic components market. While many of us will argue that it is the wireless connection that is truly in vogue, but the fact remains that wires and cables have managed to remain indispensable to the efficient functioning of many electronic products - connecting them to a power source, a network or other devices. Of recent their potential have been further acknowledged in the aviation industry. The bandwidth capability of these wires and cables are best suited for airlines and corporate operators to load their in-flight entertainment (IFE) systems with more movies, more music, more games and more connectivity. Their advantages include smaller gauge wires and cables, better capacity and less weight. When used with different materials like Teflon types, the weight can be reduced further.


With the focus industry being shifted from consumer electronics to aviation, the applications of these electrical components expands to putting multiple types of input down the same cable. The challenge however, lies in matching that with speed, increased memory capacity and the desire to have a smaller pipe with lower weight and greater capacity.


The manufacturers and suppliers of these electrical wires and cables industry are of the opinion that desire to push more and more data down the pipeline will eventually lead to more widespread use of fiber optic cable instead of copper. The big companies like Time Warner are leading the way in the transition from coax to fiber, and many customers in places like New York are seeing fiber come right to their houses. However, to reach the aviation industry, such advancements will take some significant time.


The desire to reduce weight is the most important concern that has gripped the wire and cable industry. With companies like Emteq recently introducing new, lighter weight coaxial cables that save weight compared to conventional RG and Mil-C-17 cables, the competition is getting tougher. Another challenge for the wire and cable of electrical industry, is the realignment in OEM (Original Equipment Manufacturer) priorities that has led to a shift away from designing for functionality to designing for expediency. The aviation industry is taking great care to avoid the cluster of wires and cables that keeps sneaking out of the electronic flight bags.


The growing acceptance of these electronic flight bags have created a new market for the wire and cable industry where these EFB's are installed into a fixed mount. The coiled cord aids in the maintenance of the integrity of the wire within. The wire and cable companies can enjoy the benefit of this service by getting involved in standards-setting organizations like ARINC, which can assist them in taking account of things like cable installation and survivability when new standards for avionics are being promulgated.


The main challenge for the wire and cable industry is to get into the front end of the design and to use the knowledge that can prevent problems from occurring in the first place. However, the avionics engineers are sure to overcome these technical issues with time and precision.
