The electric cable is a medium for conducting electric current. The power cable consists of an insulator and a conductor. The conductor is a part of the cable that is used to conduct electric current, while the insulator is a cable covering material which is usually made of thermoplastic material. These conductors are made of copper and aluminum.
Aluminum is a type of light metal. Aluminum cables are most often used in large-scale electrical installations such as the State Electricity Company (PLN). This type of cable functions as a conductor of large current between electricity distribution towers.

Due to its light weight, aluminum is quite malleable and easy to work with. The lightweight nature of aluminum is beneficial when wiring must be carried out over long distances as it makes work less stringent. Aluminum also reduces corona, the electrical discharge associated with high power transmission. Because it is made of lightweight metal, it is very suitable for installing electricity transmission lines in the area of the house.
When it comes to cost, aluminum is more affordable than copper wire. With aluminum, you will need about half the amount you would need if copper wire was used. When extensive wiring needs to be carried out in your home, the difference between the two materials can provide you with significant savings.
Another advantage is that on the surface, the surface of the aluminum cable is in contact with air which can almost be oxidized at any time. However, the aluminum cable is able to protect the remaining wire from oxidation so it has a strong resistance to corrosion.
