When it comes to the use of electrical , there are some minor and unnoticeable mistakes that can lead to electrical or power flow discontinuity. Some electrical of such category can be hard to trace despite using some basic regular tools to them.
During electrification of a building, the aim is to see the whole electric bulbs and supplied the needed voltage for their expected functions. Meanwhile, lack of experience and lack of finance for the project have made some electricians start manipulating the process, such as; buying the aluminum type of in combination with the copper , etc.
had been the major used for because of the property of copper as a better conductor of electricity among other metals after the silver which is the best metal for electrical conductivity. The reason silver cannot be found easily in the market is because of the scarcity of the metal but if it is used in the making of , the will cost very high that only a few people would like to buy it, meanwhile, such is the best for the conducting of electricity.
Currently copper is dominating the market alongside the aluminum because of their availability, lower cost, and good electrical conductivity. Meanwhile among the two, copper has better property for electrical conductivity and it costs more than aluminum in the market.
When wiring a , it is necessary to use one particular type of . Ideally using copper for all the wiring is the best but if for economical purpose any other type of is considered, then the should also be used throughout the wiring rather than mixing it up with .
THE DIFFERENCE BETWEEN
The major difference that exists between copper wire and aluminum wire in terms of electrical conductivity is temperature. A copper wire with a very small diameter like the 1mm can possibly conduct a voltage that could be up to 300volts without melting, but an aluminum wire of such diameter may melt under such voltage.
PROPERTIERTIES OF & ALUMINIUM
The reason for the above problem is that the temperature in an electrical wire is proportional to the voltage passing through it. Copper as a non-ferrous metal has a very high melting temperature, unlike the aluminum that melts under moderate temperatures. The high melting temperature of copper enables it to absorb heat which is a good property for electrical conductors, but in the case of aluminum, the reverse is the case, aluminum does not get hot easily but when exposed to steady heat supply above its melting point it will melt which is the property also seen in the aluminum .
Having understood how these two , it is necessary not to join them together to complete any during except for a temporary purpose.
THE EFFECT OF JOINING & TOGETHER
If the two are joined together, during any supply of high voltage, the will heat up without melting while at the joint the folded edges of copper will cause an increase to the already existing on the line, at that edge also the folded also shares the heat directly with copper a situation that may not last before the cut itself off from the copper at the edge where the joint was made.
Though the accuracy of how this happens has not been found, I strongly believe such a situation could lead to it.
