Before acquiring the wires and cables necessary in the farm, you should think about which species better to purchase.
The largest part of the cables and wires are made of two main metal – this is copper and aluminum.
With close attention of the main properties, it should be noted that cables with conductive aluminum veins are not of the highest strength and reliability. Moreover, they have a relatively low operational period.
Aluminum cable does not form good contact, since aluminum as a metal is a very weak current conductor. However, its cost is very affordable compared to the cost of copper conductors.
Unlike aluminum, the copper cable has a number of advantages, including increased electrical conductivity and strength, as well as resistance to twisting and bends. Copper wires are much less prone to corrosion. These are the main reasons for the appearance of the demand of this material. The cost of wires and cables of their copper is several times higher than the cost of material with aluminum veins.
Therefore, on the question of choosing a cable or wire, aluminum or copper, preference should be given to the latter, of course, if the money allows this.
