Why Tinned Copper Wire is better than Bare ones?



Copper wires that are available in the market today are either bare wires, insulated with nickel or tin or bunched copper wires. The bare wires are rated under the regular bare 12 gauge copper wire.
We take a close look at how bare copper wires are different from the tinned ones.
Bare copper is a great choice in industries concerned with the manufacturing of electrical equipments and associated appliances and products. Car and domestic appliances are all driven by power connected by copper wires. Great conductivity doubled by extremely good anti-corrosion properties make copper wires made in bare form best option to be used in internal circuits as well as external relays used in transformers and over-head transmission lines. It has a fairly good tensile strength which means that it does not  get snapped in heavy rains or thunderous storms.  The durability is very promising and comes with good workable features. Bare copper wires are easy to draw and flatten and can be used with any other wires as well.

Bare copper wires are little susceptible to the damp conditions as there is no insulation protecting its outer surface. It can not be used in places that are constantly dipped in fluid or water. Oil sump tanks and marine machineries use tinned wires. These tinned wires are usually bunched or braided wires. Bare copper wires are not considered for use in motors that are constantly submerged under the oil sump tanks. Using them in submarines and oil reservoirs in offshore areas is also not feasible as they might not be able to sustain the varying water pressure and the salinity level. Tinned wires come into the picture where bare wires leave. Tinned copper wires are usually bundled in the forms of braids or bunches.

Tinned wires are manufactured by the process of electroplating. Copper wires are coated with Tin particles by electrolysis. The coating is uniform and blends without leaving any chemical residue. Tinned copper wires are used in specialty appliances and high-grade engineering units. They are less used with gold jewelry and cosmetic surgery to fix bones and cartilages. Tinned wires are used along with the nickel plated wires and also Monel.
Tin is an ideal companion that can be used with the copper wires. It boosts the properties of the copper wires and helps them last ten to twenty times longer in life. Tin does not corrode and oxidize when exposed to rain. The electroplating prevents the interior copper walls to retain their properties even when the insulation is tapered or broken from some part.
Tinned copper wires are priced higher than the bare ones, but the investment is worth as they are sure to sustain the device long. Tin plating definitely increases the life expectancy of the bare copper wires. In addition to the insulation, it adds more grace to its appeal. Excellent resistance to humidity is the best feature that these tinned wires offer in comparison to others.

Stranded Copper Wires: Transforming the world of Metal Cables

Image
Choosing the right set of stranded copper wires for a project requires elaborate study. Not all layouts can be fitted with the stranded copper wires. Based on the wattage and current load, the proper diameter of the stranded set of copper wires is used. In domestic applications, the stranded types are usually not required. Only a wire with appropriate diameter can be placed in domestic and industrial layouts. Otherwise it causes serious fluctuations and short circuits. Most electricians fail to distinguish between the different types of metal wires used in the electrical systems. The wiring experts recommend the use of stranded copper wires where there is no limitation on the space or budget.   When it comes to use in contemporary appliances and power set-ups, the stranded copper wires have following advantages over the solid wires.    Residential purposes: The Stranded copper wire with shorter gauge diameter are used in the residential units. It saves the ov

Copper pipes: An insight about its diverse applications

Image
Copper falls in the genre of transition metals and it is used for numerous purposes. According to the historic data, it was used for the very first time during 8000 B.C. Since then, people began discovering diverse kinds of applications of this metal. During Stone Age, it was extensively used for making tools. After that, it began securing an important position in various industries. The color of this metal is reddish brown, but at times, it color turns to turquoise due to its salt. In the context of ductility, it scores really well and hence, it can be stretched and drawn into wires, without hassles. It possess high electrical and thermal conductivity and considering the same, it really doesn’t come as surprise when it is used in wide array of applications including machinery, roofing, utensils, electrical devices, plumbing, electrical wires, etc. Cooper pipes made up of copper prove to be suitable for diverse range of important applications. If you are keener to know about the dive

Wires and their terminology explained

Image
If you have your house constructed, you must have come across the electric wiring personnel spell out some words such as ‘Wire Gauge’, Ampere, Watts etc. that may have also bewildered you. At that time, you may have nodded your head giving an impression that you understand those power related jargons. However, do you actually know what these are and what these mean in practical life? Wire gauges This is actually a term for the grades of wires and capacity of wires. A Gauge of a wire, in layman’s language is the thickness of the wire or the size of the wire. There are various Gauge of wires available which support different power loads. For example a 6 gauge wire can withstand a load of up to 50 Ampere which means that this wire is appropriate for heavy power usage equipment such as air conditioner, geyser etc. Similarly, a lower gauge wire would support lower load equipment. Thus it is important that proper gauge of cables should be put to proper load. If a lower gauge wiring is su
