What are the problems associated with aluminum connection?

generally agrees that the highest quality metal to be used in the connection of the household is copper, although aluminum can also be used. The aluminum connection is commonly used to transmit electricity via the power supply network. This is because it is lighter and usually cheaper than copper. For some time, from the 1960s, aluminum cabling was used in homes as a replacement for a copper wire in a new construction. This has led to some problems that are typical of aluminum wiring if incorrectly installed, such as overheating that can lead to fires.

The most important problem with aluminum connection is referred to as cold creep. When the metal heats up, it expands and then retreats when it is cooled. This can be dangerous over the time of the electrical connection. If it goes through a sufficient number of warm -up and cooling cycles that are caused by daily use, the aluminum cabling is gradually released at the connection point. To make it even worse, hlOver time, you oxids, causing further heat accumulation when connected, causing greater electrical resistance, which in turn produces more heat.

This does not mean that aluminum wiring is inherently dangerous. With proper installation, aluminum wiring can be as safe and effective as copper. However, it also tends to not forgive bad or careless processing. Some fires from the house were caused by defective aluminum connections, including others where people were killed. In almost any case, it was poorly connected by the wiring to blame for fire, which suggests that even if the cabling was done with copper, the fire could eventually happen.

Due to the potential danger that the aluminum wire represents, it was discarded as a material for the involvement of the household in favor of copper. In addition to overheating, aluminum also presents other, smaller problems. Oxidation is the main thing that occurs when aluoxide minum sE accumulates on the surface of aluminum connection. It is an equivalent of rust, but more on aluminum than on iron or steel and is an electrical insulator, which means it does not lead electricity. This problem is worse at the connection sites and may need to clean aluminum from these connections if repairs are needed.

oxidation has few practical consequences other than corrosion, which may occur at the connection point. Another important point about aluminum is that even the best circumstances do not lead electricity or copper. This is projected into wires with a larger diameter and also a slightly increased risk of overheating even outside the connection. For all these reasons, aluminum cabling is no longer used in households, and some insurance companies for homeowners even charge customers higher premiums if their houses are connected by aluminum because of a higher perceived risk.
